Introduction of hydrogen fuel cells

Hydrogen fuel cell is a kind of efficient, safe, clean, flexible new type of power generation technology, different from the traditional battery energy storage manner to provide electricity. Hydrogen fuel cell by the electrochemical reaction between hydrogen oxygen, the chemical energy into electricity, as long as you have plenty of hydrogen and oxygen (air source), the conversion process can continue. Compared with traditional batteries, hydrogen fuel cell has the following advantages:

Working environment requirement is low, temperature adaptability good;

Long service life, high reliability;

Under the condition of hydrogen supply adequate, can work continuously.

Easy to maintenance and maintenance, low maintenance costs;

Green environmental protection, the applicable range is extensive;

A relatively small volume, light weight, convenient storage and transportation.

The working principle of hydrogen fuel cells

Internal mainly composed of the proton exchange membrane fuel cell catalyst, electrochemical reactions, diffusion layer and double plate. When the fuel cells work, its occurring within the following reaction: gas in diffusion layer diffusion reaction, when reaction gas reaches the catalytic layer, in be catalysts in the catalytic layer adsorption and catalytic reaction; Anodic reaction generated by proton exchange membrane to the cathode side, electronic by the external circuit to the cathode, react with oxygen molecules combine to form water, at the same time gives off heat. The electrode reaction is:

The anode (negative) : H2-2 h + + 2 e

The cathode (the anode) : 1/2 o2 + 2 h + + 2 e - H2O

Cell response: H2 o2 and H2O + 1/2
