In the present invention is disclosed a method for producing a membrane for direct liquid fuel cell, which comprises polymerizing and curing a polymerizable composition containing at least na) an aromatic polymerizable monomer wherein one polymerizable group, at least one hydrogen atom, and at least one substituent selected from the group consisting of methyl group and alkyl group having two or more carbon atoms are bonded to the aromatic ring and, when the number of methyl groups bonded to the aromatic ring is one or more, at least one of the methyl groups is bonded to the aromatic ring at the para-position relative to the polymerizable group, nb) divinylbenzene, and nc) a polymerization initiator, nwith a porous membrane to fill the polymerizable composition in the pores of the porous membrane, then polymerizing and curing the polymerizable composition, thereafter introducing a cation exchange group into the aromatic ring derived from the aromatic polymerizable monomer. |
