FIELD: electrics.
SUBSTANCE: invention concerns fuel cells (FC) with solid electrolyte. Invention claims FC containing membrane electrode assembly (MEA) with external surface of anode electrode; anode plate adjoining the external MEA electrode surface and connected to it by sealing gasket. Combined sealing gasket, external electrode surface and anode plate form closed space to be filled with fluid medium for anode fluid delivery to external electrode surface. The space to be filled with fluid medium includes porous diffusion material sheet, and at least one chamber is formed by at least one side end of diffusion material sheet and sealing gasket. Fluid medium can be delivered to active MEA surface through the chamber and by diffusion over diffusion material in sufficient amount without the necessity to make fluid medium delivery channels in anode plate.
EFFECT: increased specific electric parameters.
