PROBLEM TO BE SOLVED: To provide a fuel cell system in which circulation amount can be controlled by suppressing complication of the system.SOLUTION: Pure water can be supplied, as reforming fluid, to a fuel gas supply path 15 by means of a water pump 18. Momentum of fuel gas can be controlled by supplying pure water. Consequently, flow rate of off gas flowing through a recycle path 16 can be controlled. Consequently, even if pressure change in the recycle path 16 changes over time, and the amount of off gas sucked by an ejector 19 changes, the circulation amount can be controlled by the water pump 18. Complication even of a system using an ejector 19 can thereby be suppressed. |
