Electrolyte cation types control electrochemical reactions on an electrode surface
1. An international research group consisting of NIMS and the Finnish University of Jyväskylä has discovered through its electrode-electrolyte system research that electron and proton (i.e., hydrogen ion) transfer mechanisms during oxygen reduction reactions (ORRs) on electrode surfaces vary depending on the types of cations dissolved in the electrolytic solution. These results suggest that the energy conversion efficiencies and selectivity of electrochemical systems (e.g., fuel cells and water electrolysis hydrogen production systems) can be improved by selecting optimal reaction pathways and that this could be achieved without using expensive electrode ...
