燃料电池进气进水温度控制系统、控制方法及新能源汽车

本发明公开了一种燃料电池进气进水温度控制系统、控制方法及新能源汽车，控制方法，包括：预先在燃料电池堆的空气入口通道上的中冷器处设置加热装置；若燃料电池堆处于冷启动阶段，则控制燃料电池堆的冷却液出堆口排出的冷却液不经过散热器，且由所述加热装置加热后被泵入燃料电池堆的冷却液入堆口；否则控制加热装置停止工作，且控制燃料电池堆的冷却液出堆口排出的冷却液先经过散热器，然后被同时泵至燃料电池堆的冷却液入堆口和燃料电池堆的冷却液出堆口。本发明减少系统低温冷启动时间，有效提升冷启动速度；空气、冷却液两腔同时加热，加热均匀，避免单一加热造成温差过大而导致电堆内部损坏。 The invention discloses a fuel cell air inlet and water inlet temperature control system and method and a new energy automobile, and the control method comprises the steps: arranging a heating device at an intercooler on an air inlet channel of a fuel cell stack in advance; if the fuel cell stack is in the cold start stage, cooling liquid discharged from a cooling liquid stack outlet of the fuel cell stack is controlled not to pass through a radiator, and the cooling liquid is pumped into a cooling liquid stack inlet of the fuel cell stack after being heated by the heating device; otherwise, the heating device is controlled to stop working, and the cooling liquid discharged from the cooling liquid stack outlet of the fuel cell stack is
