Process for producing polymeric films for use as fuel cells |
| abstract |
The process for preparing polymers such as polybenzimidazole (PBI) films forms a porous membrane by solidifying the polymer dope solution in a non-solvent alone or in a liquid coagulation bath containing a nonsolvent and a solvent mixture, and the resulting membrane Immerse in non-solvent bath to remove residual solvent, place membrane in acid solution to fill pores with acid solution and dry membrane to remove residual non-solvent to destroy porous structure, capture acid and form dense film Is provided. Another method involves coagulating the polymer solution directly with an acid / solvent / non-solvent mixture to make a porous membrane to absorb the acid solution and then dry. |
