The ionomers, gas diffusion layers (GDLs), bipolar plates, and interfaces thrust is studying how ionomers in electrode layers and membranes interact with catalysts and support materials and determining how to design interfaces between the membrane, the catalyst layer, the GDLs, and bipolar plates to get the highest-performing individual cell components.
FC-PAD is researching membranes and ionomer films to:
FC-PAD is researching GDLs to examine water-transport controls and impacts through in-situ and accelerated stress test (AST) characterization.
FC-PAD is researching bipolar plates to examine leachate ions and corrosion products and contact resistance.
FC-PAD is researching interfaces to investigate the GDL/channel droplet interface, catalyst layer interface, and areas of high porosity.
