ELECTRICAL LEAKAGE DEDECTION APPARATUS AND ELECTRICAL LEAKAGE DETECTION METHOD FOR FUEL CELL

摘要

An electrical leakage detection apparatus (12) for a fuel cell (11) includes a voltage detector (55) that detects a voltage applied to coolant in a fuel cell (11) ; an electrical leakage determining portion that determines that electrical leakage has occurred when the voltage detected by the voltage detector (12) is equal to or higher than a voltage threshold value; a resistance value detector (56) that detects a resistance value of the coolant in the fuel cell (11) ; 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 (56) .
