Abstract
An electrolyte membrane including (i) a porous mat of nanofibres, wherein the nanofibres are composed of a non-ionically conducting heterocyclic-based polymer, the heterocyclic-based polymer comprising basic functional groups and being soluble in organic solvent; and (ii) an ion-conducting polymer which is a partially- or fully-fluorinated sulphonic acid polymer. The porous mat is essentially fully impregnated with ion-conducting polymer, and the thickness of the porous mat in the electrolyte membrane is distributed across at least 80% of the thickness of the electrolyte membrane. Such a membrane is of use in a proton exchange membrane fuel cell or an electrolyser.
