Effect of membrane-electrode-assembly configuration on proton exchange membrane fuel cell performance

다국어 초록 (Multilingual Abstract)

Four different membrane-electrode-assemblies (MEAs) with single and dual-layer gas diffusion layers(GDLs) at the anode and the cathode were prepared to examine polarization characteristics that rely on MEA configuration.
Porous structure of single and dual-layer GDLs was investigated using a mercury porosimeter. An MEA withdual-layer GDLs at each electrode demonstrated higher performance with an air feed. To comprehend the improvement,the impedance behavior at various current densities and polarization behavior under back pressure were analyzedin terms of oxygen diffusion processes that control catalyst utilization in the gas diffusion electrode.
