Improvement of Polymer Electrolyte Fuel Cell by Heat Transport Device

对用于聚合物电解质燃料电池（PEFC）热管理的平板热管和蒸汽压力驱动热管进行了研究。制作了热管的原型，并通过基础实验揭示了热管的传热特性。利用平板式热管进行传热，利用蒸汽压驱动热管进行温度控制，有望提高PEFC的性能。

Investigations are carried out on a flat-plate type heat pipe and a vapor-pressure-driven heat pipe for thermal management of a polymer electrolyte fuel cell (PEFC). Prototypes of these heat pipes are fabricated, and their heat transport characteristics are disclosed by fundamental experiments. It is expected that PEFC could be improved by spreading the heat with the flat-plate type heat pipe and controlling the temperature with the vapor-pressure-driven heat pipe.
