通过时间分辨率为 100 ms 的原位时间分辨 X 射线吸收精细结构，系统分析了聚合物电解质燃料电池膜电极组件中 Pt/C 阴极电催化剂在瞬态电压加载过程中的过渡态。结果表明，在 0-30 秒内快速和逐渐加载期间，Pt 阴极电催化剂的局部配位不受瞬态电压的影响。
The transitional states of a Pt/C cathode electrocatalyst in the membrane electrode assembly of a polymer electrolyte fuel cell during loading with transient voltages were systematically analyzed by in situ time-resolved X-ray absorption fine structure with time resolution of 100 ms. The results suggest that the local coordination of the Pt cathode electrocatalyst was unaffected by the transient voltages during both rapid and gradual loading over 0–30 s.
