摘　　要：本研究介绍了质子交换膜燃料电池的产热与散热问题,阐述了具有高热导率的纳米流体的制备过程和热物理性质的测量技术,并总结了近年来纳米流体在质子交换膜燃料电池(PEMFC)中作为冷却剂的应用现状。表明纳米流体在不影响电性能的条件下,可以提高热导率,减小散热器正面表面积,但会使纳米流体粘度增大,从而增加抽运水泵的功率。给出了对今后纳米流体作为PEMFC冷却剂需要改进与完善的一些建议。Hydrogen fuel cell is pure and clear energy that can convert hydrogen and oxygen directly into electrical energy with only water and some heat created,which has great potential in the application such as automobiles.This paper briefly introduces the issue of heat generation and heat dissipation of proton exchange membrane fuel cell,and emphasizing on the preparation process of high thermal conductivity nanofluid,and the measuring technique of thermophysical property.The application status in recent years of nanofluid as the coolant in proton exchange membrane fuel cells(PEMFC)has also been summarized.The result shows that under the condition of not affecting the electrical properties,the nanofluid can improve the thermal conductivity and reduce the front surface area of the radiator,but it can increase the viscosity of nanofluid and improve the power of the pump.Finally,some suggestions which are needed for improving and perfecting the nanofluid as PEMFC coolants in the future are put forward.
