Removing fluorine elements from circulating water that cools a fuel cell power generation system increases the durability of metal piping etc. of a water circulation path of this system. The fuel cell power generation system is provided with: a fuel cell main body 4, a water circulation path 8, and a fluoride absorber 6 provided in at least a portion of the water circulation path 8. The fluoride absorber 6 absorbs fluorine elements from water flowing through the water circulation path 8.
