Oxygen reduction kinetics of high performance BaCo0.4Fe0.4 M 0.1Y0.1O3-δ (M = Mg, Zr) positrode for protonic ceramic fuel cells

Abstract Protonic ceramic fuel cells (PCFCs) should exhibit high performance at intermediate temperatures in the range of 400–600 °C. To reduce the operating temperature, more active air electrodes (positrodes) are needed. In the present work, BaCo0.4Fe0.4Mg0.1Y0.1O3-δ (BCFMY) is investigated as a p...
