Abstract: A preparation process of composite membrane for fuel cells uses an expanded polytetrafluoroethylene microporous base membrane as a skeleton. The base membrane is subjected to an impregnation treatment of mixed solutions having different concentrations from low to high. Specifically, the treatment tank I is provide with a mixed solution of a 0.1 wt. %-1 wt. % perfluorosulfonic acid resin solution, a water-retaining agent and a free radical quencher, the treatment tank II is provided with a mixed solution of a 2 wt. %-6 wt. % perfluorosulfonic acid resin solution, a water-retaining agent and a free radical quencher, and the treatment tank III is provided with a mixed solution of a 7 wt. %-20 wt. % perfluorosulfonic acid resin solution and a sulfonated polyetheretherketone solution. The resulting proton exchange composite membrane does not generate pore residues and avoids hydrogen permeation when in use.
