Electrical Leakage Detection Apparatus and Electrical Leakage Detection Method For Fuel Cell |
摘要 |
An electrical leakage detection apparatus for a fuel cell includes a voltage detector that detects a voltage applied to coolant in a fuel cell; an electrical leakage determining portion that determines that electrical leakage has occurred when the voltage detected by the voltage detector is equal to or higher than a voltage threshold value; a resistance value detector that detects a resistance value of the coolant in the fuel cell; and a correction portion that corrects the voltage threshold value such that the voltage threshold value is increased with an increase in the resistance value detected by the resistance value detector.
