<P>PROBLEM TO BE SOLVED: To realize both suppression of freezing in the system and improvement in fuel consumption at low-temperature starting. <P>SOLUTION: The fuel cell system is provided with a fuel cell which generates power by receiving a gas and a control part for controlling a sweep current from the fuel cell to a power feeding object. The control part, when the stack temperature at the starting of the system (Step S1) is a prescribed freezing temperature or less (S3:NO), increases constantly the sweep current value (Step S5) until the stack temperature becomes a prescribed freezing temperature or more (Step S3:YES). <P>COPYRIGHT: (C)2007,JPO&INPIT |
