PROBLEM TO BE SOLVED: To provide a fuel cell power generation unit capable of feeding water to a water tank storing water for steam reforming, without using a pump and prolonging the service life. SOLUTION: This fuel cell power generation unit is equipped with a reforming device 10 for generation reformed gas, a solid polymer fuel cell 20 for generating electricity by introducing the reformed gas, and the water tank 1 for storing water for steam reforming. Furthermore, a reformed gas steam separator 2 for separating surplus moisture from the reformed gas and a reformed off gas steam separator 3 for separating surplus moisture from reformed off gas are provided. A normally closed type solenoid valve 6a is disposed in a first pipe 8 for connecting a lower part of the reformed gas steam separator 2 and a lower part of the water tank. A normally closed type solenoid valve 6b is disposed in a second pipe 9 for connecting the lower part of the reformed off gas steam separator 3 and the lower part of the water tank 1.
