Development and characterization of gas diffusion layer using carbon slurry dispersed by ammonium lauryl sulfate for proton exchange member fuel cells

Gas diffusion layers (GDLs) are a critical and essential part of proton exchange membrane fuel cells (PEMFCs). They carry out various important functions such as transportation of reactants to and from the reaction sites. The material properties and structural characteristics of the substrate and the microporous layer strongly influence fuel cell performance.
