The objective of this research is to develop innovative materials, assembly configuration and operation modes for polymer membrane (PEM) fuel cell stacks and fuel cell hybrid vehicle power trains through a reliability engineering process. Specifically this research is to develop reliability and component effectiveness models for polymer membrane (PEM) fuel cell stacks, and fuel cell power trains including linkage of the failure modes to material degradation phenomenon. As PEM fuel cells approach commercialization in automotive applications in 2015, the need to understand degradation and failure mechanisms is even greater. The overall approach is to develop failure mode correlations and models at the single cell level first; then to use these models in the development of stack life cycle models, and finally to scale up model into actual hybrid power train models for vehicles and other applications. Information and modelling will allow for diagnosis and prediction of the life of the electrochemical power sources, and facilitate a 'model based design' approach. It will be critical to understand their performance at both beginning of life and end of life (EOL). Consumer expectations such a vehicle performance, efficiency, range, life and cost will be greatly affected by power train configurations and control strategies. The control strategies must be able to adapt to the vehicle's drive cycle, environmental condition, and electrochemical power source state of health (SOH) over the life of the vehicle. ******

本研究的目的是通过可靠性工程过程开发聚合物膜（PEM）燃料电池堆和燃料电池混合动力汽车动力系统的创新材料，组件配置和操作模式。 具体来说，这项研究是开发可靠性和组件的有效性模型的聚合物膜（PEM）燃料电池堆，燃料电池动力系统，包括链接的故障模式，材料降解现象。 随着PEM燃料电池在2015年接近汽车应用的商业化，了解退化和故障机制的需求更大。 总体方法是首先在单电池水平上开发故障模式相关性和模型;然后在电池堆生命周期模型的开发中使用这些模型，最后将模型放大到车辆和其他应用的实际混合动力传动系模型中。 信息和建模将允许诊断和预测的电化学电源的寿命，并促进“基于模型的设计”的方法。了解它们在寿命开始和寿命结束（EOL）时的性能至关重要。 消费者对车辆性能、效率、续航里程、寿命和成本的期望将受到动力传动系统配置和控制策略的极大影响。 控制策略必须能够适应车辆整个寿命周期内的车辆行驶循环、环境条件和电化学电源健康状态（SOH）。 ******
