    Researchers from Kanazawa University, the University of Tokyo and HORIBA, Ltd. have shown that the initial state of platinum-on-carbon (Pt/C) catalyst particles before they are mixed with an ionomer strongly influences how a polymer electrolyte fuel cell (PEFC) catalyst ink subsequently develops.…
