Determination of active surface area and gas permeability of fuel cell catalyst layers

Within a hydrogen fuel cell, the cathode catalyst layer (CCL) is generally considered a limiting component in overall performance due to sluggish oxygen reduction reaction kinetics. The proposed internship is comprised of two projects, each characterizing the materials used in the CCL. The first project will investigate the permeability of oxygen, nitrogen, and helium gases […]
