ABSTRACT:
A fuel cell system includes: a fuel cell which generates electrical power from a chemical reaction of a reaction gas; a discharge path for discharging the reaction gas supplied to the fuel cell; a discharge valve which is provided in the discharge path and discharges the reaction gas from the discharge path; and valve control units for controlling opening of the discharge valve, wherein the valve control units are adapted such that, since the discharge valve has been opened by a valve open command issued by one of the valve control units, the valve control units prohibit the discharge valve from being opened by a valve open command issued by any of the other valve control units until a predetermined time period elapses.
