High-Current Density Durability of Pt/C and PtCo/C Catalysts at Similar Particle Sizes in PEMFCs

Nagappan Ramaswamy et al.

Summary: The durability of carbon supported PtCo-alloy based nanoparticle catalysts is crucial for the longevity of proton-exchange membrane fuel cells in electric vehicle applications. Factors causing performance degradation of PtCo-based cathode catalyst layers over time include ECSA loss, specific activity loss, H+/O-2-transport changes, and Co2+ contamination effects. Accelerated stress test voltage cycling protocol compares the durability of Pt and PtCo catalysts, revealing that PtCo catalysts exhibit larger cell voltage loss at high current densities due to secondary effects of leached Co2+ cations contaminating the electrode ionomer. A 1D performance model quantifies cell voltage losses from various degradation factors of the membrane electrode assembly.
