The Pt/C catalysts applied in proton exchange membrane fuel cell (PEMFC) suffer CO poisoning the anode, which notably deteriorates device performance. metal–support interaction that decreases oxidation stripping potential is a suitable way to prevent anchoring active sites can reduce or even avoid poisoning. Herein, Pt supported by amorphous NbO x ( = 1.0–2.5) and CNT form Pt@NbO + catalyst, not only displays lower initial peak but also exhibits striking anti‐CO hydrogen reaction properties. for of catalyst are 0.162 0.332 V, respectively. Moreover, PEMFC based on 100 ppm CO/H 2 power density 1.98 W cm −2 , 17% reduction compared pure remains 10 h stability at 0.4 V.
