Abstract
Provided are a polymer membrane that includes a porous polymer matrix and an acryl-based polymer infiltrated in pores of the porous polymer matrix, a method of preparing the same, and a fuel cell using the polymer membrane. The polymer membrane effectively decreases a crossover phenomenon of a fuel cell.
Claims21
A polymer membrane comprising:
- a porous polymer matrix;
- and
- an acryl-based polymer infiltrated in pores of the porous polymer matrix.
A method of preparing a polymer membrane, the method comprising:
- preparing a porous polymer matrix;
- mixing an acryl polyol and a hardener with a solvent to prepare an infiltration solution;
- infiltrating the porous polymer matrix with the infiltration solution;
- and
- heating the infiltrated porous polymer matrix to remove the solvent and to harden the infiltration solution.
