Apparatus, mechanism and process for warming-up fuel cell

摘要

Hydrogen stored in a high-pressure tank 21 is supplied to a metal hydride (MH) tank 31 to be occluded. Cooling water of a cooling system C 1 for a fuel cell 10 is heated through the heat generated at this time to warm-up the fuel cell. By such a configuration, the fuel cell can be warmed up without consuming the valuable hydrogen.
