Abstract

This work demonstrates a thermal stable nanoporous cathode with atomic layer deposited ZrO2 capping and Pt-Ni alloying to effectively inhibit the thermal agglomeration of nanoporous Pt. The ZrO2 capping is found to confine the surface nanoporous morphology and Pt alloying with Ni is found to constrain its underlaying microstructure at high temperature operation of 450 �°C. The output current using ZrO2 capped PtNi cathode has a significant improved stability, comparing with pure Pt cathode. The material characterization and electrical impedance spectrum were discussed towards the enhanced thermal stability and electrochemical behaviors.
