<P>PROBLEM TO BE SOLVED: To provide a power source system enhancing power generation efficiency by effectively using hydrogen formed by reforming fuel for power generation without enlarging a system size, complicating control, and increasing product cost; and to provide a control device and a control method of the power source system. <P>SOLUTION: When temperature in a fuel reforming part 100 does not coincide with a previously set temperature condition (set temperature), control increasing or decreasing a current value of output current taken out of a power generation cell part 150 is conducted, and the amount of hydrogen (a hydrogen utilization factor) utilizing in electrochemical reaction in the power generation cell part 150 is controlled. Temperature of the fuel reforming part 100 is adjusted by varying the amount of heat energy produced with an offgas catalytic combustor 140 by relatively increasing or decreasing the amount of hydrogen contained in offgas exhausted from the power generation cell part 150. <P>COPYRIGHT: (C)2007,JPO&INPIT |
