PURPOSE:To shorten the time for raising a temperature in starting by firstly raising the temperature of a cell body by means of an outside heat source in starting the operation of the fuel cell, and starting the operation of a low load to raise it up to the operating temperature when it exceeds given temperature. CONSTITUTION:A fuel cell power generation system is constituted to include a reformer 1 which incorporates a reforming pipe 4 reforming from methanol and water to gas abundant in hydrogen and a device 3 to control its exhaust gas, recycle gas from a cell body 2 and outside air by means of the temperature of the cell body 2. And, in starting, firstly, the burning of the methanol and the air is carried out within the reformer 1 to raise the temperature of the cell body 2 by means of the exhaust gas, and when reaching to given temperature the cell body 2 is operated with a low load, and the cell body is controlled to raise the temperature up to the operating temperature by means of its internal heating. Accordingly, it is possible to extremely shorten the starting time by using jointly with the outside heating and the internal heating. |
