Document Type and Number:
Japanese Patent JP5460798
Kind Code:
B2
Abstract:
A fuel cell comprising a membrane-electrode assembly having an anode electrode face; an anode plate adjacent said membrane-electrode assembly electrode face and coupled thereto by a sealing gasket. The sealing gasket, electrode face and anode plate together define a fluid containment volume for delivery of anode fluid to the electrode face. A sheet of porous diffuser material is situated in the fluid containment volume and having at least one plenum defined between at least one lateral edge of the sheet of diffuser material and the sealing gasket. Fluid for delivery to an active surface of the membrane-electrode assembly may be delivered by the plenum and by diffusion through the diffuser material to such an extent that fluid flow channels in the anode plate are not required.
