Abstract:

In recent years, the durability of high temperature proton exchange membrane fuel cell (HT-PEMFC) under steady-state operation has been greatly improved. However, dynamic or abnormal operations still seriously limit the lifetime of HT-PEMFC. In this regard, this paper systematically summarized the characteristics and degradation mechanism of HT-PEMFC under common operating conditions and the corresponding mitigation strategies. Moreover, the accelerated stress testing protocols and life prediction methods were sorted out. Finally, the future development of HT-PEMFC was prospected. With the advancement of the commercialization of HT-PEMFC, the development of new online detection/diagnosis technologies, the establishments of standardized testing protocols and life prediction models, the optimization of system structure and the design of assembling process and production line are likely to be the focus of future researches.

摘要:

近些年高温质子交换膜燃料电池(HT-PEMFC)在稳态操作条件下的耐久性已经得到了巨大的改善,然而动态或异常操作条件仍严重影响了HT-PEMFC的寿命。针对该问题,本文概述了HT-PEMFC常见操作条件的特点,系统地总结了常见动态或异常操作条件下电池性能的衰减机理及其相应的缓解策略,并整理了该领域内报道的加速应力测试方案与寿命预测方法。最后本文对HT-PEMFC未来的发展进行了展望,随着HT-PEMFC商品化进程的推进,未来新型在线检测/诊断技术的开发、标准化测试方案与寿命预测模型的建立、电堆或系统结构的优化以及装配工艺与生产线的设计等很有可能成为该领域内的研究重点。
