Platinum group metal (PGM)-free oxygen reduction reaction (ORR) catalysts are of utmost importance for the rapid development anion-exchange membrane fuel cell (AEMFC) technology. In this work, we demonstrate improved ORR performance and stability Co Fe oxide-decorated/N-doped reduced graphene oxide (CoOx-Fe3O4/N-rGO) prepared via a hydrothermal method at low temperature 150 °C. The were charact...

The separator is a critical component for the performance of alkaline water electrolysis as it ensures ionic contact between electrodes and prevents product gases from mixing. While conductivity affects cell voltage, permeability dissolved influences gas impurity. Currently, diaphragms are used separators, pore system which filled with electrolyte solution to enable exchange ions. breakthrough ...
