Title:
燃料電池におけるガス漏れ検知方法
Document Type and Number:
Japanese Patent JP4162874
Kind Code:
B2
Abstract:
In order to improve detecting accuracy in a gas leak detection for a fuel cell (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 which 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.
