The activity of catalyst could be enhanced by the temperature rising, so it is a suitable way to reduce the noble metal loading for the catalyst. However, the corrosion of carbon supports will be remarkable in the high temperature proton exchange membrane fuel cells (HT-PEMFC, >100 °C). This report demonstrated a novel Ti₃C₂T_x and CNT hybrid material as the catalytic support, and Pt nanowires (Pt NWs) is loaded on the hybrid support to construct the catalyst for HT-PEMFC. The Pt NWs/Ti₃C₂T_x-CNT performs higher electrochemical activity, better stability than that of commercial Pt/C. The mass activity and specific activity of Pt NWs/Ti₃C₂T_x-CNT catalysts are 3.89 and 3.02 times as that of Pt/C, respectively. The power densities of HT-PEMFC showed 155.4 mW cm⁻² and 182 mW cm⁻² at 150 and 180 °C, respectively.

温度升高可以提高催化剂的活性，因此是降低催化剂中贵金属负载量的合适方法。但是，碳质载体的腐蚀在高温质子交换膜燃料电池（HT-PEMFC，> 100°C）中会很明显。该报告证明了新型的Ti ₃ C ₂ T _x和CNT杂化材料作为催化载体，并且Pt纳米线（Pt NWs）负载在杂化载体上以构建HT-PEMFC的催化剂。Pt NWs / Ti ₃ C ₂ T _x -CNT比市售Pt / C具有更高的电化学活性和更好的稳定性。Pt NWs / Ti ₃ C ₂的质量活度和比活度T _x -CNT催化剂分别是Pt / C的3.89和3.02倍。HT-PEMFC的功率密度在150和180°C下分别显示为155.4 mW cm ^-2和182 mW cm ^-2。
