ABSTRACT:
The present invention provides a solid electrolyte with high ion-conductivity which is cheap and exhibits high conductivity in an alkaline form, and stably keeps high conductivity because of a small amount of the leak of a compound bearing conductivity even in a wet state. The invention is useful in an electrochemical system using the solid electrolyte, such as a fuel cell.The solid electrolyte with high ion-conductivity comprises a hybrid compound which contains at least polyvinyl alcohol and a zirconic acid compound, and also a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine, obtained by hydrolyzing a zirconium salt or an oxyzirconium salt in a solution including water, polyvinyl alcohol, a zirconium salt or an oxyzirconium salt and a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine coexist, removing a solvent and contacting with alkali.
