PROBLEM TO BE SOLVED: To provide a fuel cell power generation device capable of supplying moisture to an oxidant gas without using a device for humidification and needing the running costs.SOLUTION: A fuel cell stack 10 is provided with a communication pipeline 21 for connecting an oxidant gas supply pipeline 14, which supplies an oxidant gas, with the side of a cooling plate of a coolant circulation pipeline 19, in which a coolant to be supplied to a fuel cell circulates, to add the coolant recovering reaction heat of the fuel cell to the oxidant gas. The structure eliminates the need of a humidifier and energy for humidification and is able to add moisture needed for power generation reaction to the oxidant gas. |
