<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of efficiently generating electric power, while keeping the temperature of a fuel cell at a protection temperature or lower. <P>SOLUTION: The fuel cell system 1 makes a limiting rate amount negative, until the temperature becomes a second threshold which is lower than a first threshold, or lower, when the temperature detected with a coolant temperature changing amount calculation part 46 is the first threshold, which is lower than the prescribed fuel cell protection temperature, or higher. Especially, when the temperature changing amount detected with the coolant temperature changing amount calculation part 46 is a prescribed convergence decision value or larger, the limiting rate amount is made in a prescribed negative value; and when temperature detected with the coolant temperature changing amount calculation part 46 is higher than the first threshold and the temperature changing amount detected with the coolant temperature changing amount calculation part 46 is smaller than the convergence decision value, the limiting rate amount is made larger than the prescribed negative value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
