Stage: PROBLEM TO BE SOLVED: To reduce the risk of the design pressure of a fuel gas system being exceeded even when an ambient temperature rises while a fuel cell stack or a fuel cell module is in an operation stopping state and the pressure in the fuel gas system rises.SOLUTION: A fuel cell system includes: a fuel cell module that has a fuel cell stack; a fuel gas system that supplies fuel gas to the fuel cell stack; an upstream block valve and a downstream block valve that open and close the fuel gas system; a vent system that is provided by being branched from the fuel gas system between the upstream block valve and the downstream block valve; and a bleed valve that opens and closes the vent system. When executing the operational stop of the fuel cell stack, pressure reduction control is performed in which the upstream block valve is closed and then the bleed valve is opened, and after a predetermined time has elapsed, the downstream block valve is closed.SELECTED DRAWING: Figure 3 (Grant)
