Fuel cell electrode
Patent
·
OSTI ID:5857859
Fuel-cell electrodes, particularly gas-diffusion electrodes, commonly employ a supported electrocatalyst comprising a high-surface-area metal or alloy supported by porous carbon. Nitrogen-containing groups affixed to the surface of the carbon provide a force interaction between themselves and the electrocatalyst metal or alloy, helping maintain a high metal surface area during fuel-cell operation. Designed for fabrication into a diffusion electrode for phosphoric-acid fuel cells, this improved electrocatalyst and support uses amide groups chemically bonded to the carbon particles supporting a platinum catalyst. The electrode's stability contributes to a high fuel-cell performance for long periods of operation.
