Abstract:
1. A fuel cell system having an electricity generator that generates electricity by electrochemical reaction between hydrogen containing fuel and oxygen containing gas in an anode electrode and a cathode electrode, the electricity generator comprising: a membrane electrode assembly including an ionic conductive polymer membrane, and the anode and cathode electrodes are provided on opposite sides of the ionic conductive polymer membrane; a pair of separator plates facing the anode and cathode electrodes of the membrane electrode assembly and having channels through which flow the hydrogen containing fuel or the oxygen containing gas to be supplied to the electrodes; and a pair of gaskets provided on opposite sides of the ionic conductive polymer membrane to surround respective peripheries 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 comprising a nonconductive first frame and a conductive second frame.
