    • It is an object to provide a solid electrolyte and an electrochemical system using the solid electrolyte which has a little expansion (swelling) and whose strength does not decrease in case of positioning the solid electrolyte including a complex compound composed of an inorganic compound, polyvinyl alcohol, and water, in a wet condition. It is possible to use the solid electrolyte in a device such as a fuel cell or an electrolytic device used with the wet condition. The solid electrolyte has a little size variation even if humidity varies and has a low methanol permeability. The solid electrolyte is produced by replacing a part or all of hydroxyl groups of polyvinyl alcohol domain to groups each of which has a water absorption less than that of said hydroxyl group, in the solid electrolyte including a complex compound which is composed of polyvinyl alcohol, water, and at least one inorganic compound selected from silicic acid compound, tungstic acid compound, molybdic acid compound, stannic acid compound, and zirconic acid compound.

    • 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.
