Characterization of electrodes and performance tests on MEAs with varying platinum content and under various operational conditions

摘要: Abstract The characterization of electrodes and performance tests for membrane electrode assemblies (MEAs) with varying Pt content have been carried out. were made using a spraying method. physical properties the (i.e., surface structure, distribution catalysts) characterized scanning electron microscope–energy-dispersive X-ray spectroscopy (SEM–EDX), MEA performed through fuel cell test station catalyst content, temperature applied back pressure. indicated that was uniformly dispersed on both cross section layer (CL), loading between 7.5 21.5 wt%. current–voltage performances generally increased content. Similarly, use pressure increasing operation improved performance.
