A fuel cell system having an electricity generator that generates electricity by the electrochemical reaction between hydrogen and oxygen. The electricity generator includes a membrane electrode assembly with a conductive polymer membrane, and anode and cathode electrode layers on opposite sides of the conductive polymer membrane. The electricity generator has a pair of separator plates facing the anode and cathode electrode layers of the membrane electrode assembly and having channels through which flow hydrogen containing fuel or oxygen containing gas. There is also a pair of gaskets provided on opposite sides of the ionic conductive polymer to enclose each edge of the anode and cathode electrodes so that fluid leakage is prevented between the ionic conductive polymer membrane and the separator plates, wherein at least one of the gaskets is used as a voltage measuring gasket including a nonconductive first frame and a conductive second frame. The voltage measuring gasket having the conductive frame is used for measuring the voltage of the unit cell, thereby preventing a bipolar plate from being damaged.

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.
