Method for producing a polymer film for use as a fuel cell |
| abstract |
(57) [Summary]nForming a porous membrane by coagulating the polymer dope solution in a liquid coagulation bath containing a non-solvent alone or a mixture of a non-solvent and a solvent; and forming the resulting membrane in a non-solvent bath. Removing the residual solvent by submerging the membrane; placing the membrane in an acid solution, thereby filling the pores with the acid solution; drying the membrane to remove residual non-solvent and crush the porous structure And accumulating an acid to form a dense film, thereby providing a method of making a film of a polymer, such as polybenzimidazole (PBI). An alternative method comprises coagulating the polymer solution directly in an acid / solvent / non-solvent mixture to produce a porous membrane that absorbs the acid solution, followed by drying. |
