Improving polymer electrolyte fuel cell performance through optimizing flow channels and catalyst layers

Proton exchange membrane (PEM) fuel cells show great promise and are becoming more prevalent in both the automotive and stationary applications. To enhance their commercial viability, continuous efforts are essential to improve the performance and reduce costs. Consequently, the primary objective of this thesis is to conduct numerical investigations aimed at optimizing the flow channel configuration and the microstructure of the catalyst agglomerate, with the ultimate goal of enhancing fuel cell performance and cost-effectiveness.
