The invention aims to reduce degradation of the power generation performance of a fuel cell during a prolonged high load operation with high effectiveness. A fuel cell vehicle correlates the dryness of an electrolyte membrane to the cell temperature, while performing power generation control of a fuel cell based on a power demand for a driving motor. When the cell temperature exceeds a first temperature alpha that indicates the increased dryness of the electrolyte membrane, the fuel cell vehicle intermittently repeats temporary current increase control that shifts the operation state of the fuel cell to the state of an increased electric current and a decreased voltage in a time period t, in order to increase the amount of water production on a cathode. |
