摘要: A fuel cell power plant comprises plural fuel cell stacks (10A–10B) capable of generating power independently, and a warm-up circuit (33) which can independently warm up the fuel cell stacks (10A–10C). A controller (14) estimates a required output power of the power plant within a predetermined time from when the vehicle starts running (S121–S127), and determines the number of fuel cell stacks satisfying the required output power (S106). The controller (14) economizes energy required for warm-up of the fuel cell stacks while providing the required output power by warming up only the determined number of fuel cell stacks before the vehicle starts running.

摘要: A reformer (3) supplies a reformate gas to a fuel cell stack (4). The reformer (3) generates a reformate gas by reforming gaseous fuel vaporized by a vaporizer (2). When current supply from the fuel cell stack (4) to the electric motor (21) undergoes a sharp decrease, unnecessary consumption of gaseous fuel is prevented by closing a first valve (11) which supplies gaseous fuel from the vaporizer (2) to the reformer (3) and by opening a second valve (13) which returns gaseous fuel in the vaporizer (2) to the fuel tank (6).
