Evaluation for sintering of electrocatalysts and its effect on voltage drops in high-temperature proton exchange membrane fuel cells (HT-PEMFC)

Durability performance such as sintering and voltage drops of HT-PEMFC was theoretically evaluated under non-humid conditions at 150 °C, 170 °C and 190 °C. The quantum chemical molecular dynamics showed that the affinity of the platinum (Pt) electrocatalysts with carbon support decreased with increa...
