A short review of aging mechanism modeling of proton exchange membrane fuel cell in transportation applications

This paper presents a short review of the aging mechanism modeling of proton exchange membrane (PEM) fuel cell in automotive applications. The fuel cell aging mechanism is particularly important for fuel cell transportation applications, because the degradation rates of a fuel cell could increase very fast when operating at different transient conditions, such as: load cycles, start-stop cycles, fuel starvation, high temperature or low humidification. The objective of this paper is to give a state-of-the-art introduction of models for different PEM fuel cell aging phenomena. In the first part of this paper, a summary and analyses of the different aging phenomena that can be observed in PEM fuel cell are made based on literature review. Secondly, a summary of some mathematical PEMFC aging phenomena models is presented, with a focus on the models that describe the aging phenomena related specifically to automotive applications.
