Anode and cathode electrodes for a fuel cell consist of catalyst loaded onto a gas diffusion layer (GDL). ElectroChem's gas diffusion electrodes are used in both PAFC and PEM fuel cells. We use Platinum/Carbon catalyst with various loadings laminated to a hydrophobic gas diffusion layer (graphite fiber paper or cloth is considered to be the best.) If you are looking for a special size, shape, catalyst loading -- or a different backing material -- please let us know by going to our customization page.
