PROBLEM TO BE SOLVED: To provide a fuel cell system which can reduce the amount of dew condensation water at warming-up time, thereby improving fuel economy and merchantability.SOLUTION: In a fuel cell 10, a range from first load to second load at which the amount of dew condensation water is relatively small, that is, a power generation output (current) region where the amount of dew condensation water until completion of warming-up is relatively large exceeding a designated water amount Wq (i.e., a large dew condensation water current region B) is predefined by a region lower limit value and a region upper limit value, and which region is handled as a current region which is not used in power generation during warming-up. Furthermore, when the remaining capacity detected by a SOC detection sensor 62 is less than a designated value and the required load detected by required load detection means 63 exists within a load region which is larger than the first load (region lower limit value) and less than the second load (region upper limit value) (i.e., a large dew condensation water current region B), larger power than the required load is output from the fuel cell 10 and excess power is charged to a power storage device 60 via a DC/DC converter 61. |
