Membrane Electrode Assembly (MEA, Membrane Electrode Assembly), also known as membrane electrode, is the key core component of fuel cell power generation. It consists of gas diffusion layer, catalytic layer and proton exchange membrane.
The hydrogen gas reaches the anode through the gas flow field on the anode plate, reaches the anode catalyst layer through the diffusion layer on the electrode, and is adsorbed on the anode catalyst layer. 2 electrons are released. This process is called hydrogen anodization,
