PURPOSE:To make safe operation of power generating continuously with a fuel cell even when it is not possible to perform the heat exhaust process with its exhaust heat processing device. CONSTITUTION:The output of a fuel cell is supplied through a cell output control device 12. If the exhaust heat collecting heat-exchanger 7 is not capable of exhausting the heat emitted by the body 1 of the fuel cell to the outside of the cell coolant system, a control device 5 measures the pressure in a stream separator 3 using a pressure sensor 6, controls the cell output control device 12 so that the pressure becomes constant, and decreases the amount of power generation of the fuel cell. This discreasing causes the heat emission amount at power generating to balance with the natural heat radiating, etc., makes constant the reacting temp. of the fuel cell, and permits continued operation of power generation while the heat exhaust process to outside the cell coolant system is no more needed. |
