Fuel cell system, fuel cell, and hydrogen gas supplying tank

摘要

A shut valve for a hydrogen occluding alloy tank is integrated into a body of the hydrogen occluding alloy tank. Shut valves for a fuel cell are also integrated into a body of the fuel cell. There is no flow passage for communication between the shut valves and the body of the fuel cell. Therefore, it is possible to avoid a situation in which hydrogen gas continues to flow out of the flow passage for communication between the shut valves and the body of the fuel cell despite closure of the valves in response to an inconvenience arising in the flow passage. Even in case of emergency, flow of hydrogen gas can be stopped completely.
