    摘要: The present invention is intended to provide a process for producing an electrolyte membrane-bonded electrode having excellent power generation property when constitutes an electrode assembly, and a varnish composition for an electrolyte, by the use of which an electrolyte membrane-electrode bonded structure capable of retaining excellent power generation property is obtained. A process for producing a first electrolyte membrane-bonded electrode comprises applying, onto an electrode, a water-containing dispersion containing a perfluorosulfonic acid polymer, an organic solvent A and water and having a perfluorosulfonic acid polymer content of 0.5 to 20% by weight and then applying, onto the resulting film, a solution of sulfonated polyarylene in an organic solvent B, to form an electrolyte membrane. A process for producing a second electrolyte membrane-bonded electrode comprises applying, onto an electrode, a solution or dispersion containing a proton-conductive polymer, an organic solvent B and water and having a water content of 25 to 50% by weight and then applying, onto the resulting film, a solution or dispersion containing a proton-conductive polymer, an organic solvent B and water and having a water content of less than 25% by weight, to form an electrolyte membrane. A process for producing a third electrolyte membrane-bonded electrode comprises applying, onto an electrode, a varnish composition 6 obtained by dissolving a sulfonated polymer in a solvent containing an organic solvent C, an organic solvent D and water to form an electrolyte membrane, said organic solvent C being a good solvent for the sulfonated polymer and having a higher boiling point than that of other solvent components, said organic solvent D having a boiling point of not lower than 50° C. and being not a good solvent for the sulfonated polymer when used alone but causing a solubility region of the sulfonated polymer to appear when mixed with the organic solvent C and/or the water. The varnish composition 6 of the invention is a varnish composition obtained by dissolving the sulfonated polymer in a solvent containing an organic solvent C, an organic solvent D and water.
