In order to prevent the fuel economy from being lowered by a wasteful discharge of fuel gas, in the operation method of a fuel cell system capable of performing intermittent operation for temporarily stopping power generation of the fuel cell, in the case where the secondary pressure of the tank regulator becomes at least a first threshold during intermittent operation, the intermittent operation is stopped and the normal operation is returned. In the case where the intermittent operation is stopped a number of times, subsequent intermittent operation may be prohibited.
