摘要:

质子交换膜燃料电池(proton exchange membrane fuel cellPEMFC)的耐久性是制约其商业化发展的一个重要因素。影响PEMFC寿命的因素非常多,而车载燃料电池发动机不可避免的要经历频繁启停的工况,那么如何减少PEMFC电堆在启停过程中的性能衰减是至关重要的。本文主要介绍了PEMFC在启停过程中衰减的机理,并从启停控制策略的角度,综述了改进PEMFC寿命和耐久性的办法,指出了研究中所存在的问题,提出了启停控制策略研究的发展方向。

Abstract:

The relatively short life of proton exchange membrane fuel cellsPEMFCis a significant barrier to their commercialization in stationary and mobile applications. The long-term performance and durability of PEMFC are influenced by many parameters. Howeverautomotive fuel cell engine is inevitable to be experienced frequent startup and shutdown conditions. Thereforeit is essential to investigate system strategies to mitigate carbon corrosion in the frequent startup and shutdown conditions. The research development is reviewed from the point of PEMFC decay mechanism and system strategies in improving the long-term performance and durability. Existing problems and development trends are discussed.
