a, d The PEMFC performance of SA-Ru@Pt/MoCx and commercial PtRu based MEA in H2-O2 and H2 + 10,000 ppm CO-O2 environment. The Pt loading is 0.1 mg cm−2. All the gas is 100% relative humidity (RH) and the cell temperature was set at 80 °C with 200 kPa back pressure. b, c, e, f The power-time curves for SA-Ru@Pt/MoCx and commercial PtRu based MEA with H2 + 10,000 ppm CO and H2 + 20,000 ppm CO as anode gas respectively.
