Abstract:
In a method for detecting the freezing of water within a fuel cell, precise detection can be performed using a phenomenon specific to the time when water starts to freeze to allow a reduction in erroneous activation. Detection at an early stage after the start of freezing is allowed, and hence measures can be taken against an output reduction before the water within the fuel cell completely freezes.
