    • PURPOSE: A preparation method of a nano fibrous membrane is provided to impart mechanical and physical properties uses as a fuel cell to an electrospinning fiber film and to effectively prepare a sulfurnated polymer pore-filled electrospun nano fibrous membrane. CONSTITUTION: A preparation method of a sulfurnated polymer pore-filled electrospun nano fibrous membrane for a proton exchange membrane fuel cell or direct methanol fuel cell comprises the steps of: (i) preparing a nano fibrous membrane by electrospinning a polymer solution; (ii) filling styrene or vinyl monomer inside pores of electrospinned nano fibrous membrane obtained from the step (i) into pores of the nano fibrous membrane and then inducing graft-copolymerization; and (iii) treating the polymer pore-filled electrospun nano fibrous membrane with a sulfonating agent and the sulfonating polymer chains.
