Unparalleled mitigation of membrane degradation in fuel cells <i>via</i> a counter-intuitive approach: suppression of H₂O₂ production at the hydrogen anode using a Pt_skin–PtCo catalyst

Abstract

PtCo/C_HT anode catalyst showed a large suppression of H₂O₂ generation, by ≥50% in comparison with commercial Pt/CB at practical potentials for H₂ oxidation, resulting in greatly enhanced durability of the fuel cell by mitigating membrane degradation.
