Abstract:Widespread commercialization of proton exchange membrane fuel cells (PEMFCs) still requires optimization of various components for extended lifetime and high performance, even under harsh operating conditions. In this work, the PEM was studied in detail, using different perfluorinated sulfonic acid (PFSA) ionomers with short and long side chains, low-and highequivalent weight (EW), and varying relative humidity. The PEMs were carefully characterized electrochemically in fuel cell tests. The performance and ion… Show more
