[PROBLEMS] To quickly and optimally control the water condition and tempe rature of a fuel cell even when the fuel cell is at a low temperature and in a dry state. [MEANS FOR SOLVING PROBLEMS] If it is determined that a fuel c ell is in a dry state (YES in step S120) and is determined that the fuel cel l is at a low temperature (YES in step S130), a control device performs a lo w-efficiency power generation (step S140). Performing the low-efficiency pow er generation makes it possible to quickly warm up the fuel cell and bring t he cathode water balance of the fuel cell (2) into a plus (wet) state, so th at the water condition and temperature of the fuel cell can be quickly and o ptimally controlled. |
