Abstract
A fuel cell system includes: 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 the 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.

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 the 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, and
- the heat exchange line includes:
- a circulation route (A) to circulate the heat exchange medium between at least one of the reactor vessels and the cooling device;
- circulation route (B) to circulate the heat exchange medium between at least one of 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.
