Transition to success
Kim and co-workers demonstrate a HOR-selective electrocatalytic process imparted by a metal–insulator transition to mitigate degradation of the cathode catalyst layer during start-up/shut-down of PEMFCs for automotive applications. Platinum nanoparticles supported on hydrogen tungsten bronze (Pt/H x WO3) suppressed the ORR with a metal–insulator transition under exposure to oxygen, while selectively promoting the HOR by regaining metallic conductivity under exposure to hydrogen.
