Platinum-carbon Cloth Electrodes
GDE
The Platinum-carbon cloth electrodes for environmentally friendly and efficient fuel cells made in China from Hycircle, which is one of the manufacturers and suppliers in China.
The so-called gas distribution layer is located in the middle of the electrode. With very little pressure, electrolytes are displaced from this porous system. The small flow resistance ensures that the gas can flow freely inside the electrode. At slightly higher air pressure, the electrolytes in the pore system are confined to the working layer. The surface layer itself has such fine holes that gas cannot flow through the electrodes into the electrolyte, even at peak pressure. This electrode is made by dispersion and subsequent sintering or hot pressing. To produce multilayer electrodes, fine-grained materials are dispersed in a mold and smoothed. Then, other materials are applied in multiple layers and pressure is applied.

Quantity
In fuel cells, GDE (gas diffusion electrode) is a critical component. It prepares a membrane electrode assembly (MEA) by coating the catalyst on the gas diffusion layer and combining the gas
diffusion electrode and proton exchange membrane using hot pressing method. This technology enables GDE to serve as the cathode for oxygen reduction reaction (ORR) and the anode for
hydrogen oxidation reaction in fuel cells.
We usually spray catalysts onto PEM (CCM), but we also offer customized GDE.
