Disclosed is a method for producing a membrane for direct liquid fuel cells, wherein a polymerizable composition is brought into contact with a porous membrane so that voids of the porous membrane are filled with the polymerizable composition, then the polymerizable composition is cured by polymerization, and after that a halogenoalkyl group in the resin membrane is converted into a quaternary ammonium group. In this method, the polymerizable composition contains (a) an aromatic polymerizable monomer having an aromatic ring wherein one polymerizable group, at least one halogenoalkyl group and a group which is inert to a reaction converting the at least one halogenoalkyl group into a quaternary ammonium group, are bonded together, (b) a crosslinkable polymerizable monomer and (c) a polymerization initiator.
本发明公开了一种用于生产直接液体燃料电池膜的方法,其中将可聚合组合物与多孔膜接触,使多孔膜的空隙充满可聚合组合物,然后通过聚合固化可聚合组合物,之后将树脂膜中的卤代烷基转化为季铵基团。在这种方法中,可聚合组合物包含:(a) 具有芳香环的芳香族可聚合单体,其中一个可聚合基团、至少一个卤代烷基和一个对将至少一个卤代烷基转化为季铵基的反应惰性的基团键合在一起;(b) 可交联的可聚合单体;(c) 聚合引发剂。
