    摘要: The present invention restores the performance of a fuel cell by: operating the cell in a loaded current mode different from that of a normal operation for a predetermined time; supplying an oxidant gas and a fuel gas to an anode and a cathode respectively and outputting a current from a cell body with the polarity being inverted; supplying a pressurized gas to at least one of the cathode and anode in an amount not less than 1.5 times as much as that in the normal operation or supplying oxygen to the cathode; or injecting a cleaning solution into the cathode and anode through a gas flow path. Consequently, it is possible to effectively restore a degraded performance of a polymer electrolyte fuel cell caused by a long operation.

    摘要: In a fuel cell system including a stack of polymer electrolyte fuel cells, the wet state of electrolyte membranes in the fuel cell stack is detected according to a variation in measurement value of an alternating current impedance (AC impedance) of the fuel cell stack. In an adequate level of water content of the electrolyte membranes, the measurement value of the AC impedance is substantially constant and has a very little variation. In an excess level of water content of the electrolyte membranes, the measurement value of the AC impedance has a significant variation. The AC impedance of the fuel cell stack is determinable by frequency analysis of high-frequency noise generated by an inverter included in the fuel cell system.
