PGM and PGM-free Catalysts for Polymer Electrolyte Membrane Fuel Cells

In this review, we highlight the recent progress in both PGM and PGM-free ORR catalysts for PEMFC applications. In addition, the remaining challenges in ORR catalyst development that meet the targets of PEMFC applications beyond the preliminary half-cell test are also discussed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
