    Abstract: PURPOSE: An ion exchange composite membrane, its preparation method, a composite solution, and a fuel cell containing the membrane are provided, wherein the membrane intercepts methanol selectively without deterioration of the diffusion of hydrogen ions. CONSTITUTION: The ion exchange composite membrane comprises clay or organic clay dispersed into an ion conductive polymer film. Preferably the clay or organic clay is inserted into or coated on an ion conductive polymer film. The clay is at least one selected from the group consisting of pyrophylite-talc, smectite (montmorillonite), vermiculite, illite, mica and brittle mica group. The ion conductive polymer has at least one group selected from the group consisting of sulfonate, carboxylate, phosphate, imide, sulfonimide and sulfonamide, and is preferably nafion or sulfonated polystyrene-block-ply(ethylene-ran-butylene)-block-polystyrene. Preferably the fuel cell is a direct methanol fuel cell using methanol as a fuel.
