摘　　要：传统燃油汽车排放的大量尾气对环境造成了严重的污染,氢燃料电池汽车的出现能够很好地解决环境污染的问题。燃料电池内部工作会伴随着大量热的产生,散热慢,则会导致电堆温度过高,易使质子交换膜出现脱水现象,严重时甚至会发生破裂;电堆温度低,则不利于电化学反应的发生,降低输出性能。此外,单电池之间的温度分布不均匀会导致热应力的产生,严重影响电堆的耐久性。质子交换膜燃料电池运行温度较低,其与环境之间的自然对流换热与辐射换热能力有限,绝大部分热量需要借助热管理系统排出。The large amount of exhaust emissions from traditional fuel powered vehicles has also caused significant environmental pollution,and the emergence of hydrogen fuel cell vehicles can effectively solve the above problems.The internal operation of fuel cells is accompanied by a large amount of heat generation.Slow heat dissipation can lead to excessively high stack temperature,which can easily cause dehydration of the proton exchange membrane,and in severe cases,even rupture;Low stack temperature is not conducive to the occurrence of electrochemical reactions and reduces output performance.In addition,the uneven temperature distribution between single cells will lead to the generation of thermal stress,which seriously affects the durability of the stack.The operating temperature of proton exchange membrane fuel cells is relatively low,and their natural convective and radiative heat transfer capabilities with the environment are limited.The vast majority of heat needs to be removed through a thermal management system.
