REINFORCED ION-CONDUCTING MEMBRANE
Reinforced ion-conducting membrane According to the present invention there is provided a reinforced ion-conducting membrane comprising: an ion-conducting polymer; and a porous mat of nanofibres. The porous mat of nanofibres is impregnated with the ion-conducting polymer. The nanofibres comprise a cross-linked polymer, wherein the cross-linked polymer is ionically non-conductive. The cross-linked polymer comprises: a heterocyclic-based polymer backbone comprising basic functional groups, and linking chains linking at least two heterocyclic-based polymer backbones via linking groups. The porous mat of nanofibres has a tear index of at least 15 mN m.sup.2/g.
