摘要：A method of fabricating a membrane electrode assembly, comprising: obtaininga mixture by mixing and kneading electrically conductive particles, a polymer resin, a
surfactant, and a dispersion solvent (S); obtaining a sheet-like mixture by rolling out andshaping the mixture (S); obtaining a carbon sheet by heat-treating the sheet-like mixtureat a first heat treatment temperature such that the surfactant and the dispersion solventare removed from the sheet-like mixture (S); obtaining a dispersion liquid by mixingelectrically conductive particles, a polymer resin, a surfactant, and a dispersion solvent (S);forming, on the carbon sheet, a dispersion liquid layer thinner than the carbon sheet byforming and drying a coating of the dispersion liquid on the carbon sheet (S); obtaining agas diffusion layer in which a carbon layer is formed on the carbon sheet, by heat-treatingthe carbon sheet on which the dispersion liquid layer is formed at a second heattreatment temperature lower than the first heat treatment temperature such that thesurfactant and the dispersion solvent are removed from the dispersion liquid layer (S);and stacking a catalyst layer and an electrolyte membrane in said order on the carbonlayer (S).
