Proton conducting materials and membranes and electrochemical devices incorporating the materials and membranes are provided. Also provided are methods of making the materials and membranes and methods of operating the electrochemical devices. The proton conducting materials are solid acids that form superprotonic phases at elevated temperatures. The superprotonic phases have a cubic structure and the general formula: MH]HPO, where M represents one or more monovalent cations or a combination of monovalent cations and divalent cations, 0<x≤2/9, and y is a number that provides charge balancing.

Cesium-deficient cesium phosphates for proton conducting electrolytes

Materials for electrochemical cells are provided. BaZrCeMOcompounds, where M represents one or more rare earth elements, are provided for use as electrolytes. PrBaSrCoFeOis provided for use as a cathode. Also provided are electrochemical cells, such as protonic ceramic fuel cells, incorporating the compounds as electrolytes and cathodes.

Methods of forming bilayer cathodes for electrochemical cells

The present disclosure generally relates in certain embodiments to a combined cycle power plant system comprising an electrochemical compressor. For instance, in one set of embodiments, the electrochemical compressor is may separate oxygen from a flow of air from an air source to provide a pressurized flow of oxygen to a combustor. In some embodiments, the resulting combustion products may only include oxygen and water without any substantial fraction of other combustion products or contaminants which may facilitate the separation of carbon dioxide (CO) for subsequent processes including compression and/or storage.
