The service performance of PEFC stacks in highly dynamic applications such as the automotive industry is considerably lower than that of comparable stacks in stationary use or in moderately dynamic applications, and constitutes a decisive barrier on the path to commercialisation.
The focus of the work in this project is the experimental and modelled examination of PEM fuel cells with varying gas diffusion layers and flow field designs in a highly dynamic application and the identification of the transient states caused by dynamics which lead to an accelerated degradation of cells.
The research project consists of four work packages concentrating on parameter definition, experiments, evaluation and modelling as well as validation at the stack level.
