る。As described above, in the conventional fuel cell power generator, a circulation circuit is installed to allow heated nitrogen gas to flow through each reactor, or a heater for heating is built in the reactor. As a result, the temperature of the reforming device is raised when the device is started. However, in the method in which the heated nitrogen gas is circulated in the circulation circuit to flow through each reactor to raise the temperature, the temperature of each reactor is sequentially raised to a predetermined temperature, so the temperature rise is completed. It takes a considerable amount of time to do so. Also, if a heater for heating is built into the reactor, each reactor can be heated individually, so the heating time is shortened, but it takes some time to heat the reactor that has become low temperature to a predetermined temperature. Is required, which impedes quick startup of the fuel cell power generator. Further, in a device such as a fuel cell power generation device arranged in an urban area or a suburb of the city, which is frequently started and stopped, there is a problem that a large amount of energy is required for heating.

Therefore, when the reformer is not provided with a heat retaining means, the reformer is heated by the combustion of the raw fuel, and for example, by circulating high temperature nitrogen gas to raise the temperature, the reformer can be operated in a short time. It can be moved to the startup state. Further, if the reformer is also provided with the heat retaining means, the reformer can be activated in an extremely short period of time.
