1. A proton conducting material comprising a superprotonic phase of a solid acid, the superprotonic phase having a cubic structure and the general formula: [M(1−x)Hy]H2PO4, where M represents one or more monovalent cations or a combination of monovalent cations and divalent cations, 0<x≤0.2 2, and y is a number that provides charge balancing.
