Abstract
A fuel cell system comprises a fuel cell, a reactant gas pipe for supplying a reactant gas to the fuel cell, and an injector for controlling the state of the gas on the upstream side in the reactant gas pipe and supplying the reactant gas to the downstream side by driving a valve element with an electromagnetic drive force at a predetermined drive cycle to separate the valve element from a valve seat. The injector is provided integrally in the fuel cell, and hence the vibration and noise of the injector can be absorbed and suppressed by the fuel cell as a heavy article.
