25. Analysis of Deformation of Gas Diffusion Layers and the Impact on Performance of PEM Fuel Cells
Abstract : Proton exchange membrane (PEM) fuel cells have been promoted due to significant breakthroughs in various aspects and increasing public interests. The porous features of the gas diffusion layer (GDL) and the necessary assembly processes generate localized pressure forces on the channel/shoulder structure of the bi-polar plates (BPP). READ MORE
