Abstract
A cooling water temperature of a fuel cell 10 is detected by a sensor 94d. Based on the outside air temperature, a first threshold temperature and a second threshold temperature lower than the first threshold temperature are calculated. When it is judged that the cooling water temperature is lower than the first threshold temperature and higher than the second threshold temperature, first warmup processing is performed. When it is judged that the cooling water temperature is lower than the second threshold temperature, second warmup processing with an amount of heat generation greater than the first warmup processing is performed.
