る。BACKGROUND ART Electrochemical devices using an ion exchange resin membrane as a solid electrolyte include fuel cells, water electrolyzers, salt electrolyzers, oxygen separators, hydrochloric acid electrolyzers, and water electrolysis type humidity sensors. These electrochemical devices generally use an ion exchange resin membrane with an electrode integrally bonded thereto. Methods for bonding electrodes to ion-exchange resin membranes include hot-pressing a mixture of electrode catalyst powder and fluororesin binder (e.g., Japanese Patent Publication No. 15544/1983), and electroless plating method (e.g., Japanese Patent Publication No. 15544/1983). 55-38934) has been proposed.

た。Problems to be Solved by the Invention In conventional ion exchange resin membrane-electrode assemblies, whether using the hot pressing method or the electroless plating method, the electrode reaction site is the electrolyte at the junction between the ion exchange resin membrane and the electrode. Since it was localized to a certain two-dimensional interface, the effective area of action was small.

The above-mentioned problems are attempted to be solved by applying a mixed suspension of the above to an ion exchange resin membrane.

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 trade name Nafion Solution (mixed solvent solution of lower aliphatic alcohol and water).

イオン交換樹脂混合体は電極として作用する。 When a compound containing a catalytic metal is directly dissolved in a solution of the above 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 cations containing the catalytic metal are combined. Substitution occurs and the catalytic 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. When a solution of such an ion exchange resin or a mixed suspension of the solution and a fluororesin suspension is applied to an ion exchange resin membrane having a fluorine-containing polymer skeleton and the solvent is evaporated, ions are released. A bond between the exchange membrane and the catalytic metal-ion exchange resin mixture is formed. Note that after application, the bonding strength will be increased if the adhesive is pressed at room temperature or heated. In this way, a bonded body of the ion exchange resin membrane and the catalytic metal-ion exchange resin mixture is completed. Catalytic metal
The ion exchange resin mixture acts as an electrode.

特性が向上する。 In such an ion exchange resin membrane-electrode assembly, the ion exchange resin in the electrode also functions as a solid electrolyte, so the reaction sites are limited to the two-dimensional interface between the ion exchange resin membrane and the electrode, as in the past. Rather, it has a three-dimensional extension that includes the contact point between the catalyst metal and ion exchange resin in the electrode, increasing the effective electrode area, and making such a bonded body electrochemical. When applied to a device, polarization properties are improved.

By adding 10 cc of chloropentaammonium platinum ion ([Pt(NH 3 ) 5 Cl] 2+ ) to the solution and allowing it to stand for a while, the hydrogen ions of the sulfonic acid groups in the Nafion 117 solution were replaced with chloropentaammonium platinum ions ([Pt(NH 3 ) 5 Cl] 2+ ). Next, a 5% aqueous solution of sodium borohydride was added to reduce the chloropentaammonium platinum ions and precipitate platinum. At this time, fine platinum particles are dispersed and suspended in the solution. Next, 3 cc of a 60% aqueous suspension of polytetrafluoroethylene was added to this dispersion, and the platinum-bonded naphion 117
