Gas diffusion layer gdl
WebWet proofed gas diffusion layers (GDL with hydrophobic treatment) enable improved water transport within the fuel cell. In PEM fuel cells, specifically water retention can result in lower power generation. These GDLs are treated with Teflon in order to make the material hydrophobic and improve water transport. WebApr 26, 2024 · The compressive deformation of gas diffusion layer (GDL), which is highly nonlinear and related to the loading history, affects the performance of PEM fuel cell stacks. However, linear elastic models are widely used. In this study, a new nonlinear constitutive model is proposed to describe the compression properties.
