<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing reduction in a life of equipment such as combustion catalyst even if fuel gas supply amount is increased. <P>SOLUTION: When a voltage outputted from a cell stack device 1 gets to a predetermined value or less, a control device 9 performs fuel quantity increase operation and causes an ignition device 11 to be operated and combustion of off gas in a combustion region 10 to be accelerated. By operating the ignition device 11 ignition and combustion in the combustion region 10 is accelerated and a temperature rise in a combustion catalyst 8 is suppressed, thereby capable of suppressing deterioration of the combustion catalyst 8 and preventing reduction in a lifetime. <P>COPYRIGHT: (C)2013,JPO&INPIT |
