Hydrogen powered technologies provide a huge potential for the transition towards sustainable energy sources, e.g. for mobile applications. However, degradation effects present a significant challenge that currently constrains the practical applications of hydrogen technologies. Proton Exchange Membrane Fuel Cells (PEMFCs) are important devices for the conversion of chemical to electrical energy. For the PEMFC, the Membrane Electrode Assembly (MEA) is a key component, which is especially vulnerable to degradation mechanisms. In this research, we study novel materials for the MEA which counteract these mechanisms and which enable long lifetimes of the devices. The electrode layer is made of composite material, which consists of different components. A multiscale Finite Element Method (FEM) simulation is developed to investigate the composite material used for the electrode layer and to derive practical guidelines for experiments.
