PURPOSE:To increase total efficiency by installing a starting heating line having a starting heating medium heater and a starting heating medium pump and a power generating heating line having a power generating heating medium heater and a power generating heating medium pump. CONSTITUTION:For starting operation, to raise temperatures of a fuel cell 1 and a methanol reformer 2, an electromagnetic valve 27 is closed and electromagnetic valves 36, 38 are opened, and a power generating heating medium pump 26 and a starting heating medium pump 34 are drived to circulate heating medium into a starting heating line 35. After temperature for starting was raised, operation of a starting heating medium heater 33 is stopped, the electromagnetic valve 27 is opened and the electromagnetic valves 36, 37 are closed, the starting heating medium pump 34 is stopped, and the power generating heating medium pump 26 is continued to drive to circulate heating medium into a power generating heating line 30. Heating capacity of a power generating heating medium heater 25 is decreased compared with a conventional heating medium heater whose heating capacity is increased to shorten starting time, and heat loss caused by heat radiation is decreased. |
