PURPOSE:To continuously supply cell cooling water with stability so as to stably recover exhaust heat when the discharged heat is recovered while a temperature or pressure of the cell cooling water is kept to be constant in a fuel cell power generating system where steam generated from the cell cooling water is used for reformation of fuel. CONSTITUTION:A generated current detector 30 measures a generated current of a fuel cell 3, and inputs the result into a controller 32 which calculates a quantity of steam required for fuel reformation. An engine speed controller 31 controls a cell cooling water supplying pump 10 at an engine speed, at which cell cooling water according to the steam quantity can be supplied. Accordingly, the cell cooling water can be continuously supplied with stability. Consequently, it is possible to keep a temperature or pressure of the cell cooling water constant so as to stably recover exhaust heat from the cell cooling water. |
