Advancing Green Hydrogen Production with Innovative Materials and Coatings

Green hydrogen is a vital solution for reducing greenhouse gas emissions in various sectors of the global economy. As proton exchange membrane (PEM) electrolyzer deployments scale to meet hydrogen production demands, it is critical that raw materials and coatings used in stack designs are carefully engineered for a balance of cost, efficiency, and durability. In this presentation, we will describe technical approaches to assist in the customization of porous transport layer (PTL) components for optimal properties such as mass transport, conductivity, and corrosion resistance. In particular, the design of expanded metal sheets as PTL flow-fields will be described. Computational fluid dynamics (CFD) modeling is used to predict key hydrodynamic properties and inform the engineering of these components. With a specific focus on scalable technologies that can achieve GW/y production volumes, we will demonstrate how PTL assemblies can be economically optimized for performance, under specific PEM electrolyzer form factors and operational conditions.
