いう商標で発売されている。Function Examples of ion exchange resins having a skeleton of fluorine-containing polymers include perfluorocarbon sulfonic acid resins. It is known that perfluorocarbon sulfonic acid resins dissolve in lower aliphatic alcohols or organic solvents such as dimethyl sulfoxide under high temperature and high pressure. Such solutions of perfluorocarbon sulfonic acid resins are sold, for example, by Aldrich Chemical Company of the United States under the trademark Nafion Solution (mixed solvent solution of lower aliphatic alcohol and water).

懸濁する。If a compound containing a catalytic metal is directly dissolved in the solution of the perfluorocarbon sulfonic acid resin, or an aqueous solution of a compound containing a catalytic metal is mixed, hydrogen ions of the sulfonic acid group and catalytic metal ions or catalytic metals are mixed. Substitution with cations occurs, and the catalyst metal becomes trapped in the perfluorocarbon sulfonic acid resin. When such a mixed solution is treated with a reducing agent, the catalyst metal is precipitated and finely dispersed and suspended in the ion exchange resin solution.

特性が向上する。In such an ion exchange resin membrane-electrode assembly,
Since the ion exchange resin in the electrode also functions as a solid electrolyte, the reaction site is not only the two-dimensional interface between the ion exchange resin membrane and the electrode as in the past, but also the reaction site between the catalyst metal and the ion exchange resin in the electrode. It has a three-dimensional spread including the contact point with the electrode, and the effective area of electrode action increases.
When such a conjugate is applied to an electrochemical device, the polarization characteristics are improved.
