VEHICLE FUEL CELL POWER PLANT WARM-UP CONTROL

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.
