Fuel cell system

A fuel cell system, comprising:

• a plurality of reactor vessels containing a hydrogen storage material;
• a hydrogen tank storing a hydrogen gas;
• a fuel cell;
• a cooling device to dissipate exhaust heat from the reactor vessels or the fuel cell to outside;
• a hydrogen gas line that can switch supply routes of the hydrogen gas among the reactor vessels, the hydrogen tank, and the fuel cell;
• a heat exchange line that can switch circulation routes of a heat exchange medium among the reactor vessels, the fuel cell, and the cooling device;
• and
• a control mechanism to switch the supply routes of the hydrogen gas and the circulation routes of the heat exchange medium,
• wherein the hydrogen gas line includes:
• a supply route (A) to supply the hydrogen gas from the hydrogen tank to at least one of the reactor vessels;
• a supply route (B) to supply the hydrogen gas from at least one of the reactor vessels to the fuel cell;
• and
• a supply route (C) to supply the hydrogen gas from the hydrogen tank to the fuel cell, supply route (C) being formed from one or more pipes or valves directly connecting the hydrogen tank to the fuel cell, and
• the heat exchange line includes:
• a circulation route (A) to directly circulate the heat exchange medium between at least one of the reactor vessels and the cooling device;
• a circulation route (B) to circulate the heat exchange medium between at least one of the reactor vessels and the fuel cell, circulation route (B) being formed by one or more pipes or valves that directly connect the reactor vessels and the fuel cell;
• and
• a circulation route (C) to circulate the heat exchange medium between the fuel cell and the cooling device.
