ABSTRACT:
A plate type fuel cell system includes: an electric generator including a membrane-electrode assembly having a plurality of anode electrodes and a plurality of cathode electrodes arranged on opposite surfaces of a proton-exchange membrane and spaced apart from each other; an anode separator facing the plurality of anode electrodes and having a fluid channel adapted to receive a hydrogen containing fuel; a cathode separator facing the plurality of cathode electrodes and having an air ventilating hole; a fuel distributor having an accommodating part defined by a rib to accommodate the anode separator and adapted to distribute the hydrogen containing fuel to each of the plurality of anode electrodes, the rib being partially cut out to define a rib cutting part; and a sealing member contained within the rib cutting part. With this configuration, reaction fluid, such as a hydrogen containing fuel, is effectively prevented from leaking through the rib cutting part or a frame cutting part, thereby enhancing the stability of a stack and the power generation efficiency of the fuel cell system.
