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.

摘要： A fuel cell electrode is proposed which has a positive electrode layer (20), a negative electrode layer (19) and an ion exchange film (21) interposed between these. Before a solution for making one of the other of positive and negative electrodes has dried, a solution for making the ion exchange film is applied to it, and then a solution for making the other electrode is applied while the solution for making the ion exchange film is not yet dry. Because the layers are not dry, the intimacy of the layers improves. By the ion exchange film being made a solution, the applied film can be made thin.
