PURPOSE:To vary the externally recovered quantity of heat from a cell cooling water system according to the state on the side utilizing the heat in a fuel cell. CONSTITUTION:Heat transmission is conducted from a reforming gas supplied from a reformer 2 to a fuel cell body 1 to a cell cooling water system through a heat exchanger 12 for cell cooling water heating. A control device 14 controls a regulating valve 13 for cell cooling water heating on the basis of an external set signal of heat recovered quantity, whereby the heat transmitting quantity is controlled. Thus, the quantity of the heat recovered from the cell cooling water system to the outside through an exhaust heat recovering heat exchanger 4 can be varied according to the state on the side utilizing the recovered heat. |
