What material is the electrode of fuel cell?

1. Hydrogen-oxygen fuel cell, in which hydrogen is introduced into the cathode and oxygen is introduced into the anode, and generally inert metal platinum or graphite is used as the electrode material;

2. Methanol fuel cell, with inert metal platinum as two electrodes and alkali or acid as electrolyte;

3. Methane fuel cell, with porous nickel plate as two electrodes and potassium hydroxide as electrolyte solution;

4. Most new fuel cells use inert metal and catalytic metal as two electrodes.
