Impact of the Cathode Layer Printing Process on the Performance of MEA Integrating PGM Free Catalyst

In this work, platinum group metal (PGM) free-based cathode active layers were prepared using different printing techniques. The membrane electrode assemblies (MEAs) integrate a PGM free catalyst based on Fe, N and C atoms at the side. Scanning electron microscopy (SEM) images of MEA cross sections showed strong impact fabrication process structure, porosity ionomer repartition. MEAs characterized in 25 cm2 single cell cyclic voltammetry under H2/N2. performance double layer capacity cathodes also shown to be linked used. comparison electrochemical accessible surface its area (SBET) led determination utilization factor. coated (CCM) made decal transfer gives best performances.
