Abstract: The conductivity of cesium hydrosulfate-phosphate single crystals obtained for the first time has been studied. It has been shown that these single crystals undergo a phase transition to a state with superprotonic conductivity. It has been found that the state with high proton conductivity is retained during thermal cycling for a long time and has a quasi-reversible nature.
