What is a device for producing hydrogen by electrolysis of water?

Device for producing hydrogen by electrolysis of water: using water as raw material, it consists of a water electrolyzer, a gas-liquid separator of hydrogen (oxygen), hydrogen (oxygen) cooler, hydrogen (oxygen) gas purifier, etc. . A collective noun for a combination of equipment.

The principle of hydrogen production by water electrolysis: 2H2O= (power supply) 2H2+O2 (both gases must be marked with gas symbols), the role of soda is: conductivity, Since pure water is a weak electrolyte and has poor conductivity, sodium hydroxide is a strong electrolyte and increases conductivity.

Explanation of related content:

Electrolyzer, frame (including auxiliary equipment); rectifier cabinet; water supply pump; raw material water tank; . The production of hydrogen by electrolysis of water is a methodmore practical ode. Direct current passes through an electrolytic cell filled with potassium hydroxide or sodium hydroxide, and the water molecules undergo an electrochemical reaction on the electrodes and decompose into hydrogen and oxygen.

The formula of the chemical reaction is as follows: Cathode: 2H2O+2eH2↑+2OH Anode: 2OH—2eH2O+1/2O2↑ Overall formula of the reaction: 2H2O2H2↑+O2↑ According to the law of In Faraday electrolysis, gas production is proportional to current, regardless of other factors.

There are several types of hydrogen production by water electrolysis

The device for producing hydrogen by water electrolysis water involves applying direct current to the electrolyte in the water electrolyzer produces liquid hydrogen and oxygen at the cathode and anode respectively, which are then sent to the hydrogen separator and two ways oxygen separator for sepagravity ration. Hydrogen and oxygen are sent upwards to the gas point. , while the electrolyte flows downwards by reflux. It is collected in the circulation pump and then sent to the electrolyzer for electrolysis, thereby generating hydrogen and oxygen back and forth.

During this process, it is necessary to ensure the balance of liquid levels in the hydrogen separator and the oxygen separator to avoid the risk of blowout caused by gas-liquid crosstalk. liquid level balance is achieved by This is achieved by adjusting the gas pressure in the two separators.

A device for electrolyzing water to produce hydrogen includes a piezoelectric cantilever beam and a rectifier circuit. The piezoelectric cantilever beam is connected to the rectifier circuit. The rectifier circuit is connected to the electrolyzer. a cantilever beam basex. The piezoelectric cantilever beam is connected to the rectifier circuit, electrodes covered with the material, stainless steel plate, stainless steel plate and cantilever beam base. The piezoelectric material is layered up and down at the intersection of the stainless steel plate and the base of the cantilever beam, and both sides of each layer are covered with electrodes.

The method of electrolysis of water to produce hydrogen, the stainless steel plate on the piezoelectric cantilever beam is connected to a low-frequency mechanical vibration and energy vibration is converted into electrical energy. The rectifier circuit conducts electricity to. the electrolyzer starts to electrolyze water and uses a hydrogen collection device and an oxygen collection device respectively for collection.

Compared to traditional electrolysis of water to producehydrogen, it improves the efficiency of energy conversion, reduces costs, guarantees the purity of the hydrogen and oxygen produced, improves the safety of the collection process and does not require a greenhouse. Gas emission.

There are two types of hydrogen production by water electrolysis; they are divided into acidic and alkaline conditions

1.Conditions:

Cathode: 4H2O+4e-=2H2↑ +4OH-

Anode: 4OH-- 4e-=2H2O+O2↑

Total reaction formula: 2H2O=2H2↑+ O2↑

2. Acidic conditions:

Anode: 2H2O-4e-=O2↑ +4H+

Cathode: 4H++ 4e- =2H2↑

The reaction follows Faraday's law and the gas production is proportional to the excitation current and time.

Detailed information:

When direct current passes through certain aqueous electrolyte solutions , it breaks down The substance has nothing to do with the original electrolyte. What is broken down iswater as the solvent, and the original electrolyte still remains in the water. For example, sulfuric acid, sodium hydroxide, potassium hydroxide, etc. all belong to this type of electrolytes. ?

When electrolyzing water, because pure water has a very low degree of ionization and low conductivity, it is a typical weak electrolyte. Therefore, the aforementioned electrolytes must be added to increase the conductivity of the solution. that water can smoothly electrolyze into hydrogen and oxygen

A solid polymer electrolyte, SPE electrolyzes water and was originally used to supply oxygen to spacecraft or underwater, or as a hydrogen generator in the laboratory (can be used in gas chromatography). After the large-scale development of nuclear power, people use SPE technology to electrolyze water to produce hydrogen during periodslow power consumption, and use SPE hydrogen-oxygen fuel cells to provide external power during peak power supply periods, making it an energy storage and conversion device
