The invention provides a fuel cell stack cooling system. The system comprises a fuel cell stack, a water pump, a fan, a radiator, a heat dissipation water pipe and a plurality of thermostats which areconnected through pipelines to form a cooling liquid circulation loop, and the small cooling liquid circulation loop comprises the fuel cell stack, the water pump, the thermostat C and the thermostatA; the large circulation loop comprises the fuel cell stack, the water pump, the thermostat C, a draught fan, a radiator and the thermostat B; and the thermostat C is further connected with a heat dissipation water pipe and a thermostat D in parallel. The cooling system of the fuel cell stack provided by the invention is divided into a small cycle and a large cycle, the cooling system only dissipates heat through the radiator when an automobile runs at low power, and when the power of the fuel cell stack is too high, the thermostat is started to enable a cooling liquid to pass through the designed heat dissipation water pipe so that an inlet temperature of the stack is ensured to be within a proper range.
本发明提供一种燃料电池电堆冷却系统,其特征在于:包括通过管路连接的燃料电池电堆、水泵、风机、散热器、散热水管和若干节温器,共同组成冷却液循环回路,其中冷却液小循环回路包括燃料电池电堆、水泵、节温器C和节温器A,大循环回路包括燃料电池电堆、水泵、节温器C、风机、散热器和节温器B,节温器C上还并联有散热水管和节温器D。本发明提供的燃料电池电堆的冷却系统分为小循环与大循环,当汽车以较小功率行驶时,冷却系统只通过散热器散热,当燃料电池电堆功率过大时,开启节温器使冷却液通过所设计的散热水管,保证电堆的入口温度在合适的范围内。
