Solid electrolyte comprising organic compound containing the organic polymer with hydroxyl group, inorganic compound, and water intended to provide the solid electrolyte that is less susceptible to performance deterioration even under high temperatures of 100° C. or higher and the electrochemical system using the said solid electrolyte. It is a principal object of this invention to provide the basic means for producing the solid electrolyte comprising the hybrid compound where part of or all of the hydroxyl groups of the organic polymer with hydroxyl group are combined with at least one species of phosphoric acid and boric acid by immersing the hybrid compound in the solution containing at least one species of phosphoric acid and boric acid; otherwise by coating it with the said solution. Moreover, the said hybrid compound is made by neutralizing inorganic salt by acid in the raw material solution with the organic compound containing the organic polymer with hydroxyl group coexisting, removing solvent, where the solution after the neutralization process contains at least one species of phosphoric acid and boric acid. Hereby, part of or all of the hydroxyl groups of the organic polymer with hydroxyl group are combined with at least one species of phosphoric acid and boric acid. |
