【摘  要】质子交换膜燃料电池(PEMFC)采用风冷、液冷等热管理技术,可有效传递电池多余热量。但是,需要辅助工作来驱动流体的流动,这无疑降低了电池的总功率。脉动热管(PHP)作为一种新型散热装置,由于其紧凑性,快速传热,并且没有辅助工作支持,可以在PEMFC中提供有效的热管理。

【Abstract】Proton exchange membrane fuel cell(PEMFC)adopts thermal management such as air cooling and liquid cooling techniques,which can effectively transfer the excessive heat from the cell. However,auxiliary work is needed to drive the flow of fluid,which undoubtedly reduces the total power of the battery. The pulsating heat pipe(PHP)as a novel heat dissipation device can provide perfect thermal management in the PEMFC because of its compactness,fast heat transfer,and devoid of auxiliary work support.

【Key words】PEM fuel cell;thermal management;pulsating heat pipe
