Abstract
Sulfonated silane ionomeric materials useful in electrodes of e.g., membrane electrode assemblies (MEA) of fuel cells can improve cell performance. MEAs prepared with CCE cathode catalyst layers and standard ELAT anode layers over a period of several start-stop cycles, as well as at multiple relative humidities were studied. The MEA performance was monitored using cyclic voltammetry, electrochemical impedance spectroscopy, and fuel cell polarization curves. The CCE cathode materials appeared to maintain performance and had improved water management capabilities at comparatively low relative humidities.
