To confirm the superiority of newly developed electrocatalyst layer (ECL) for polymer electrolyte fuel cells, three-dimensional dispersion states of Nafion ionomer in Pt/carbon black agglomerates were analyzed by electron tomography based on multiple TEM images taken at different tilt angles. Uniform distribution of the ionomer has been first observed, proving the high catalyst utilization in the new ECL distinctive from that of the conventional one.
为了证实新开发的用于聚合物电解质燃料电池的电催化剂层（ECL）的优越性，基于在不同倾斜角度拍摄的多张透射电子显微镜（TEM）图像，通过电子断层扫描分析了铂/炭黑团聚体中全氟磺酸离子交换树脂（Nafion离聚物）的三维分散状态。首次观察到离聚物的均匀分布，这证明了新型ECL中催化剂的高利用率，与传统ECL不同。
