PROBLEM TO BE SOLVED: To provide a fuel cell system for a mobile body of high efficiency and low cost. SOLUTION: With the fuel cell system for the mobile body with power of fuel cells (4) generating electricity with reforming gas and oxygen as a driving source, the fuel cells (4) are driven at constant load when desired load value necessary for operation of the mobile body or an average value of desired load value is under the given load value, and are controlled so as to operate under varied loads according to the desired load value or the average value of the desired load value. Therefore, request for resolution and accuracy of various sensors and flow-controlling valves to be fitted to the fuel cell system is alleviated, which enables cost reduction as well as improvement of mileage by dint of a continued efficient operation. |
