Modern hydrogen generators are made with large reactors. The internal containers of the devices are filled with pieces of aluminum. An aqueous solution is also used. The principle of operation of the generator is based on the release of hydrogen and heat. Potassium in this case plays the role of a catalyst.
Many experts consider generators of this type to be inefficient. However, it should be noted that the components for the device are cheap. You can assemble the model yourself. To do this, first of all, you should familiarize yourself with the generator device.
Generator device
A standard hydrogen generator includes a small diameter tube. Most often it is installed with a round cross section. Under it are special cells with electrolyte. Directly pieces of aluminum are located in the lower tank. The electrolyte in this case is suitable only for the alkaline type. Above the feed pump is a reservoir where condensate collects.
Some models use two pumps. Temperature control is carried out directly in the cells. It should also be noted that forconnection of the device current outputs are used. Most often they are set to 10 A. The hydrogen compartment is connected to the cylinder. Many models have a cathode cavity. If we consider modifications with a caviator, then on average they have a maximum electrolysis temperature of 80 degrees. The efficiency of generators fluctuates around 70%.
Sealed Generators
With a water seal, it is quite easy to assemble a hydrogen generator with your own hands. First of all, experts recommend preparing a container for aluminum. Directly the tube is selected with a circular cross section. In this case, three cells are required. The feed pump of the model is installed above the current outlet. After fixing the container, install the caviator.
Directly, the water seal should be located on a special platform. To connect it to the hydrogen separation, a tube will be required. The membrane for these purposes is suitable for a small thickness. The current consumption in this case should not exceed 20 A. The gas productivity of such generators is low. On average, the efficiency factor fluctuates around 55%. Generator starts for about 10 seconds.
Selenoid Models
It is difficult to make a hydrogen generator with your own hands on selenoid. The model of this type is equipped with a large capacity for electrolyte. The tube with the solution must be located near the cells. The current leads are often of the spiral type. Maximumthe electrolysis temperature in the devices does not exceed 70 degrees. The feed pump is installed behind the caviator.
If we consider powerful modifications, then they use a tube with a diameter of up to 5.5 cm. On average, the current consumption in devices fluctuates around 15 A. The soft start time for models does not exceed 15 seconds.
Application of alkali solution
Modification with an alkaline solution involves the use of a special cavitation zone. How to make a hydrogen generator? To assemble the model, first of all, a container for aluminum is installed. Next, you should deal with the tube with cells. A separate container must be provided for condensate.
In some cases current leads are used of spiral type. The water seals of the models are attached behind the cells. A jacket is required to cool the system. The device is directly connected through the cathode cavity.
10 A models
A 10 A hydrogen generator is suitable for heating a small house. Tubes for models are selected with a diameter of up to 3.5 cm. In this case, the cells are installed in sequential order. Aluminum in devices of this type is used crushed. The container with the solution should be near the cells. The feed pump is most often set to low power. As a rule, models are used with water seals. Some modifications have a caviator.
Resonators are used to stabilize the solution temperature. In this case, much depends on the dimensions of the cavity forelectrolysis. Many experts advise to calculate the gas productivity before assembling the model. The determining factor in this case is the amount of loaded aluminum. Depending on it, the start time of the generator will change.
25 A devices
Hydrogen generators for heating at 25 A are in demand nowadays. Tubes in this case are selected with a circular cross section. Some experts advise installing three cells at once. The condensate tank is attached to the base of the generator. The electrolyte used is alkaline. The feed pump of the model is of low power. The current output is installed behind the cells. Cases are most often made of an open type. The caviator is used directly with the anode. Many models have a startup time of less than 10 seconds.
Modifications for 30 A
A 30 A hydrogen generator can be assembled by yourself. To do this, first of all, a large container for hydrogen is prepared. The conductor can only be used of the spiral type. The tube is standard installed with cells. Aluminum will require a separate cavity.
The feed pump in the devices is used with a stand. For condensate, a container is installed above the cells. A cathode cavity is being prepared for the current leads. A jacket is used to cool the generator. Some models have a water seal. In this case, the soft start time is less than 8 seconds.
Using pulsed resonators
Pulse hydrogen generatora resonator can only be assembled on the basis of a selector. In this case, a water seal is used with a membrane. In some cases, two condensate pipes are installed at once. Many experts advise cells to be arranged in a sequential order. The feed pump in this case must not come into contact with the hydrogen tank. A lot of aluminum is prohibited. Caviators are used with a connecting rod mechanism. The circulation of the solution takes place in a special heat exchanger.
Generators with operational resonators
Generators with operational resonators can boast of high performance. However, they are distinguished by large dimensions. On average, the efficiency of models does not exceed 80%. The tube for assembly is standardly used with a round section. However, first of all, you should do the installation of cells. To do this, a strong plate is selected on the generator. Next, it is important to install a container for hydrogen. The cavitation zone must be located at the base of the device. The heat exchanger in this case must be made small. In order to ensure the supply of electrolysis, a connecting rod mechanism is required.
NHO Generator
HHO do-it-yourself hydrogen generator can be made on the basis of a conventional caviator. In this case, only two cells are required. The tube is directly fixed on the plate. The supply pump must be located next to the hydrogen tank. A heat exchanger is used to control the electrolysis temperature.
The selector is fixed on a special stand. Condensation requires a separate container. The aluminum is directly loaded into the tank under the tube. The device is connected via a current output. This model does not have a cooling jacket. On average, an HHO hydrogen generator starts up in 10 seconds.
Devices without selenoid
Hydrogen generator for home heating without selenoid is used only with cavitation zone. On average, the efficiency of models does not exceed 80%. The advantage of these devices is considered to be a quick start. They also achieve maximum electrolysis performance. In order to assemble the model yourself, you will need a sheet of metal.
The tube in this case must be located next to the cells. The feed pump is most often used with low power. For condensate, a small container is installed. A water seal is often used with an anode. A current output must be located nearby.
