PROTON CONDUCTIVE SOLID ELECTROLYTE, ITS MANUFACTURING METHOD, AND PROTON CONDUCTIVE FUEL CELL
To provide a proton conductive solid electrolyte which exhibits a high proton conductivity in a wide temperature range from a room temperature to a high temperature of 300°C or more in the upper limit and can be manufactured at a lower baking temperature than before without using an expensive or highly toxic raw material.SOLUTION: A proton conductive solid electrolyte is represented by the compositional formula AM1-xH2x(PO3)3 yH2O, where an element A is K or Rb, and an element M is one or more elements selected from the group consisting of Ni, Zn, Co and Fe, or is the combination of Mg and one or more elements selected from the group consisting of Ni, Zn, Co and Fe, or where the element A is K and Rb, and the element M is one or more elements selected from the group consisting of Ni, Zn, Co, Fe and Mg, and where x is 0.05 or more and 0.30 or less, y is 0.3 or more and 3.0 or less, and has a predetermined structure including a tunnel type structure and has H3O+ or H+ in the tunnel type structure.SELECTED DRAWING: Figure 11
