Low-loading IrO2 supported on Pt for catalysis of PEM water electrolysis and regenerative fuel cells

[Display omitted] •IrO2 supported on Pt having a hemispheric core-shell structure was constructed to be used as OER and HOR electrode for URFC.•Significant performance, 7.1 A cm−2 at 2.0 Vcell, was achieved in PEMWE with only 0.16 mgIr cm−2 including a stability demonstrated for 220 h.•49% of round...
