PROBLEM TO BE SOLVED: To prevent deterioration or break of system caused by freezing and provide a shortened start time and steady start by having an automatic heat insulation function of a fuel cell unit in stop and storage of the system. SOLUTION: A power supply system comprises a fuel cell 11, reformed gas generating/supplying system 12, an air supply system 13, a cooling water system 14, a various kind of an auxiliary unit for supplying/circulating and heating arranged within the systems 12-14 and a fuel unit 1 having a power supply 15 for an auxiliary unit and a battery 2 as a power supply, and further comprises temperature detectors 16-19 and a monitoring/controlling unit 3. In stopping and storage of the system, the temperature detectors 16-19 automatically monitors the temperature of at least of the fuel cell body 11 and the cell cooling water. The monitoring/controlling unit 3 issues instruction into the power supply 15 for the auxiliary unit to operate the necessary auxiliary unit and the heat insulation function in the case where a measuring value obtained from the temperature detectors 16-19 is temperature requiring a heat insulation. |
