Abstract
Materials for electrochemical cells are provided. BaZr0.4Ce0.4M0.2O3 compounds, where M represents one or more rare earth elements, are provided for use as electrolytes. PrBa0.5Sr0.5Co2−xFexO5+δ is provided for use as a cathode. Also provided are electrochemical cells, such as protonic ceramic fuel cells, incorporating the compounds as electrolytes and cathodes.
