Abstract:Despite the many advantages of catalyst‐coated membranes (CCMs), there have been few studies of the use of CCMs to construct membrane‐electrode assemblies (MEAs) for high‐temperature polymer‐electrolyte membrane fuel cells (HT‐PEMFCs) using phosphoric acid (PA) doping. In this article, the use of membrane patterning to enable CCM to be utilized for HT‐PEMFCs is reported. A PA‐doped ion‐pair membrane and an electrode containing protonated phosphonic acid ionomers are employed to fabricate CCMs using the direct‐… Show more
