PURPOSE:To make a fuel cell body raisable up to the required starting temperature while controlling it according to a very strict program, by burning a part of fuel to be supplied, while recirculating generating heat and generated gas together with the remaining fuel, and raising the temperature to the extent of starting condition temperature of a fuel cell. CONSTITUTION:Energizing electric heaters 8 and 8' with a continuous rating current, a catalyzer surface is heated so as to become more than 500 deg.C, while an air feed blower 16 is driven while opening a control valve 10 slightly, and air is fed by degrees from a pipe line 9. On the catalyzer surface, combustion gets started, and heat of reaction in response to this combustion is generated there. Gas inclusive of nuburned fuel is recirculated while heating a cell pipe (or a cell pipe group) 11, and new fuel in quantity commensurate to fuel consumption is resupplied to a pipe line 5 from a PSA tower 4. Thus, combustion is continuously started at a catalytic combuster 7, whereby the cell pipe 5 is raised in temperature in succession. And, opening of the control valve 10 of the pipe line 9 is controlled so as to go along the specified temperature up program, adjusting an air feed quantity. |
