Methods of producing hydrogen

On the lessons of high school chemistry once given an explanation on the account, how to get hydrogen from ordinary water flowing from the tap. There in the chemical field is a concept - electrolysis. It is thanks to electrolysis it is possible to produce hydrogen.

The simplest hydrogen plant is a kind of container filled with water. Under a layer of water are placed two plate electrodes. These electric shocks. Since water is an excellent conductor of electrical current between the plates is contacted with a small resistance.

Passing through the low resistance current water facilitates the formation of a chemical reaction, resulting in the hydrogen formed.

Hydrogen laboratory by

Schematic of the experimental hydrogen plant, which in earlier times was studied in a high school program in chemistry classes. As it turns out, for the practice of modern everyday needs of those lessons were not redundant

It would seem that everything is simple and still quite a bit - to collect the resulting hydrogen is to use it as energy. But chemistry is never complete without the fine details.

So here: if hydrogen is combined with oxygen, at a certain concentration of an explosive mixture is formed. This moment is one of the critical phenomena, limiting the possibility of constructing a sufficiently powerful home stations.

The design of the hydrogen generator

To build hydrogen generators with their hands usually take as a basis the classical Braun installation scheme. Such average power of the electrolyzer consists of a group of cells, each of which contains a group of electrode plates. Fitting power determined by the total surface area of ​​the electrode plates.

Cells are placed inside the tank, well insulated from the outside environment. In the reservoir housing output pipes for connecting water line, the output of hydrogen, electricity as well as contact connecting bar.

Hydrogen plant Brown

Hydrogen generation apparatus designed on Brown scheme. For all calculations, this setting should ensure that it is a household heat and light. Another question - what size and power will make it (+)

Scheme Brown generator, inter alia, provides for a water seal and the check valve. Due to these elements organized installation protection hydrogen reverse stroke. According to such a scheme is not excluded theoretically build a hydrogen plant, for example, for the organization of heating a country house.

Hydrogen heating in the house

Collect hydrogen generator for efficient home heating - an invention may not be fantastic, but obviously extremely unprofitable. In order to obtain the necessary amount of hydrogen at home boiler will require not only a powerful electrolysis plant, but also a significant amount of electrical energy.

Payment spent electricity produced in the home hydrogen seems inefficient process.

Hydrogen station for home

Actual operating the hydrogen generator of domestic destinations. The only thing that upset - it's just a pilot version, the ability to develop that show how the spark ignition occurs

However, attempts to solve the problem of how to make a hydrogen generator for the house with his own hands, do not stop. With the principle of the device and one of the proven models hydrogen boiler introduce article, which we encourage you to read.

And here's an example of one of the variants of the torture:

  1. Prepared sealed reliable capacity.
  2. Made tubular or plate electrodes.
  3. It is going control circuit operating voltage and current.
  4. Made additional modules for the workstation.
  5. Selected accessories (hoses, wires, fasteners).

Naturally, the need toolkit, including special equipment, such as an oscilloscope and a frequency counter. Equipped with everything necessary, you can proceed directly to the manufacture of hydrogen of the heating system for the house.

Implementation of the project with their own hands

Initially it needs to make cell hydrogen generation. The fuel cell has dimensions slightly less than the internal dimensions of length and width of the housing of the generator. Adjustment block size of the electrodes is 2/3 of the height of the main body.

The cell can be made of Plexiglas or textolite (wall thickness 7.5 mm). To do this, cut to size five textolite plates. Of these, glued (epoxy) rectangle, the bottom part of which remains open.

The plates of the fuel cell

Approximately plexiglass plate body form hydrogen generator of the fuel cell. True, there is shown a slightly different version of engineering - for assembly and fastening screws

On the upper side of the rectangle are drilled desired number of small holes for the shanks electrode plates, one small hole for level sensor, plus one opening for 10-15 mm hydrogen exit.

Inside the rectangle placed platinum electrodes, contact tangs which are fed through the holes of the upper plate outside the cell. A water level sensor installed at around 80% fill cell. All transitions in textolite plate (except hydrogen release) is filled with an epoxy adhesive.

Cells hydrogen generator

Design feature modules depicted on the photo generator - cylindrical shape performance. Also differently executed electrodes of miniature power source

hydrogen outlet fitting hole to be equipped - to fix it mechanically, applying a seal or paste. The collected cell hydrogen generation is located inside the main body casing and the upper perimeter carefully sealed (again possible to apply an epoxy resin).

Housing hydrogen plant

Thus the housing of the hydrogen generator has been selected for the next pilot project. It draws a simple idea, but it is unlikely this variant is suitable for high-power station, designed for heating private house premises

But before you lay the cell inside the generator housing need to prepare:

  • to make feed for in the bottom waters;
  • make the top cover with fasteners;
  • to choose a reliable sealing material;
  • Place the lid on the electric terminals;
  • place on the cap a hydrogen reservoir.

The result should be ready for action in part hydrogen generator after:

  1. The fuel cell is loaded into the housing.
  2. The electrodes are connected to the terminal block cover.
  3. Hydrogen outlet fitting is connected to a hydrogen manifold.
  4. The cover is mounted on the housing through the seal and fixed.

It will only have to connect the water and add-on modules.

Additions to the hydrogen generator

Homemade apparatus for producing hydrogen supplement necessary auxiliary modules. For example, the water supply unit, which is functionally combined with a level sensor installed inside the generator.

In a simple form of such a module contains the water pump and the control by the controller. The pump is controlled by a controller of the sensor signal, depending on the water level inside the fuel cell.

Further details of the generator

Additional components that need to include any design in the hydrogen station and even experimental. Without automation devices, control and protection of the hydrogen generator can not be operated

In fact, it is also desirable to have a device which regulates the frequency of the electric current and voltage levels applied to the terminals of the fuel cell working electrode. At a minimum, an electric module must be equipped with a voltage regulator and protection against overcurrent.

Hydrogen collector, in its simplest form, looks like a tube, wherein a valve, pressure gauge located, check valve. From collector abstracted hydrogen through a check valve and in fact can already be supplied to the consumer.

hydrogen collector

Hydrogen collector and manometric measurement device - inherent hydrogen plant parts, thus ensuring a gas pressure distribution and control

But in practice, everything is more complicated. Hydrogen - explosive gas having a high combustion temperature. Therefore, just go and download the hydrogen in the boiler system as a fuel - it does not get done.

setting quality criteria

Collect qualitative effective and efficient installation at home is very difficult. For example, if even take into account such criteria as the metal, from which either already has the electrode plates or tubes the risk to run into problems.

The durability of the electrodes depends on the type of metal and its properties. You can of course use the same stainless steel, but the life span of such elements will not be long.

The electrode cell plate

A certain spoof electrode plates for the hydrogen generator. Plate taken from conventional variable capacitor that are made of aluminum. These electrodes will suffice for exactly half an hour of work, even in a small part of the experimental system

It plays an important role as mounting dimensions. Necessary calculations with high accuracy with respect to required power, water quality and other parameters.

Thus, if the gap distance between the working electrodes is out of the calculated values, the hydrogen generator can not function at all. In the worst case, the power to which the calculation was made, would be several times lower.

Even sectional view of the wire connecting the electrodes to the power source has a value in the hydrogen generator device. However, here it comes to the safe operation of the device. However, it should be taken into account and the construction detail in the home design.

Returning to the safe operation of the system, should also not forget the introduction into the structure of so-called water seal, preventing reverse movement of the gas.

Apparatus for generating hydrogen

Despite the rather impressive number of developments homemade hydrogen generators, really effective option yet. All models are inferior plant equipment

Generator industrial manufacturing

At the level of industrial production of hydrogen generators domestic use technology gradually master and develop. As a rule, power plants produced home use, where power does not exceed 1 kW.

Such apparatus is designed for the production of hydrogen fuel in a constant operation is not more than within 8 hours. Their main purpose - energy heating systems.

Also developed and produced under the operation of the installation as part of condominiums. This is the more powerful design (5-7 kW), whose purpose is not only energy heating systems, but also to generate electricity. This combined version is quickly gaining popularity in the western countries and in Japan.

Combined hydrogen generators are characterized as a system with high efficiency and low emission of carbon dioxide.

Industrial hydrogen generator

EXAMPLE actual current industrial manufacturing station power to 5 KW. Similar installations are plans to do so under equipped cottages and condos

Russian industry has also started to deal with this promising type of fuel production. In particular, the "Norilsk Nickel" is developing hydrogen technology systems, including household.

It is planned to use a variety of fuel cell types during development and production:

  • proton-exchange membrane;
  • orthophosphoric acid;
  • proton-exchange methanol;
  • alkaline;
  • Solid oxide.

Meanwhile, the electrolysis process is reversible. This fact shows that it is possible to receive already heated water without burning hydrogen.

It seems that this is another idea that can be grasped to start a new round of passion associated with free fuel production for domestic boiler.

Conclusions and useful videos on the topic

Experimenting at home with homemade models, you need to prepare for the unexpected results, but negative experiences - is also experience:

Hydrogen generators for home, made with his own hands - is yet a project that exists on the level of a single idea. Practically implemented projects of hydrogen generators with their own hands is not, and those that are positioned in the network - the imagination of the author, or purely theoretical options.

So what is left to rely on expensive commercial product that promises to appear in the near future.
