Abstract

Read online

One limiting factor to the high-performing reversible protonic ceramic electrochemical cells is the poor stability and electrocatalytic activity of air electrodes. Here the authors report a water-promoted surface restructuring process to enhance the performance of Ba0.9Co0.7Fe0.2Nb0.1O3-δ air electrode.
