<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of promptly restarting power supply when intermittent operation is completed in a short period and preventing a fuel cell from being deteriorated while improving operation efficiency when intermittent operation is performed over a long period. <P>SOLUTION: A fuel cell system 10, when it is estimated that intermittent operation is completed within a first period, executes voltage recovery control for maintaining a stack voltage Vc of a fuel battery stack 20 so that the stack voltage is not less than a first lower limit threshold value and does not execute voltage recovery control when it is estimated that intermittent operation is continued beyond the first period. <P>COPYRIGHT: (C)2013,JPO&INPIT |
