PROBLEM TO BE SOLVED: To provide a fuel cell system exhibiting high tolerance to rapid expansion to reforming water, while avoiding up-sizing of the fuel cell system, and to provide a gas flow rate limiter capable of relaxing an impulse wave when gas expands rapidly.SOLUTION: A fuel cell system includes a steam flow rate limit section 30. In a water supply line L2, the steam flow rate limit section 30 has a flow rate adjustor 32 movable between a first position x1 where the flow path cross-sectional area of the circulation space of the water supply line L2(L22, L23) is a first cross-sectional area S2, and a second position x2 where the flow path cross-sectional area of the circulation space of the water supply line L2(L22, L23) is a second cross-sectional area (S1+S2) wider than the a first cross-sectional area S2, and an energization member 35 for energizing the flow rate adjustor 32(32a) so as to be located at the second position x2.SELECTED DRAWING: Figure 3 |
