GAS LEAK DETECTION METHOD FOR FUEL CELL |
摘要 |
In order to improve detecting accuracy in a gas leak detection for a fuel ce ll (1), in a gas leak detection method for a fuel cell having a solid polymer electrolyte membrane (51) sandwiched by an anode (52) and a cathode (53), an output voltage is measured in an activated over-potential region in a state in whic h the pressure of fuel gas which is supplied to the anode (52) is maintained higher than the pressure of gas which is supplied to the cathode (53), and a gas leak is determined to exist when the output voltage is lower than a predetermined pressure value. |
