Recent years, hydrogen production using polymer electrolyte water electrolyzer has attracted attention as an energy storage system for effective utilization of renewable energy. Development of electrocatalyst with high activity and durability is required, especially anode catalysts for oxygen evolution reaction (OER). In this study, to clarify the effect of support graphene size on catalyst activity, we investigate OER activity and durability of IrO₂-N-rGO catalysts synthesized form graphite with various flake size.
