This paper proposes a hypothesis for explaining Pt/C particles' coarsening inside the catalyst layers of a PEM fuel cell. The hypothesis includes the two parts: (1) due to capillary condensation a water-bridge could be formed between two neighboring nano-scale Pt/C particles at relative humidity und
