a H2-O2 fuel cell polarization curves and power density curves before and after 30 K cycles of ADT. Anode: H2 flow rate = 200 mL min−1, 0.05 mgPt cm−2 for Pt/C; Cathode: O2 flow rate = 500 mL min−1, 0.10 mgPt cm−2 for PtNiMoAu NWs/C and 0.12 mgPt cm−2 for Pt/C. b H2-Air fuel cell polarization curves and power density curves of PtNiMoAu NWs/C and Pt/C before and after 30 K cycles of ADT. Anode: H2 flow rate = 200 mL min−1; Cathode: Air flow rate = 500 mL min−1. c Changes of MA (left, H2-O2, black and orange dash lines indicate BOL and EOL of DOE targets, respectively) and cell voltage at 0.8 A cm−1 (right, H2-Air) of PtNiMoAu NWs/C and Pt/C before and after 30 K cycles of ADT. d The changes of MEA ECSAs and e atomic percent of Ni for PtNiMoAu NWs/C, PtNiAu NWs/C, PtNiMo NWs/C, and PtNi NWs/C before and after 30 K cycles of ADT. f Comparison of BOL MA and MA retention (after 30K-cycle ADT) with those typical catalysts reported recently.
