Fig. 7: AEMFC performance of NiSA-Ru@RuO2 NSs/C.

Polarization and power density curves of AEMFC with Ni-Ru@RuO2/C (0.1 mgRu cm−2) in anode and Pt/C (0.4 mgPt cm−2) in cathode in the (a) H2/O2 condition and (b) H2/Air condition. c The PPD of NiSA-Ru@RuO2 NSs/C-based and commercial Pt/C-based MEA under H2/O2 and H2/Air media, d AEMFC stability test at the current density of 0.5 A cm−2 under the H2/Air condition with the NiSA-Ru@RuO2 NSs/C (0.1 mgRu cm−2) as the anode and the commercial Pt/C (0.4 mgPt cm−2) as the cathode.
