Abstract
A fuel cell system () includes a pressure decrease valve () and a flow control valve () provided in a hydrogen supply line (P) that extends from a high pressure gas tank () to a fuel cell (). A low temperature environment may cause the function of these devices to decrease. Therefore, if the gas temperature inside the high pressure gas tank () is higher than the temperature of this low temperature environment and is a temperature at which the decreased function can be recovered, high pressure gas inside the tank is made to flow through the hydrogen supply line (P) to expose the pressure decrease valve () and the like to the relatively high temperature gas before a start signal that starts the system is received.
