A method for forming a gas-permeable and ion-permeable membrane comprising fully impregnating a porous ion-impermeable or non-conductive polymer substrate with an ion-conducting polymer material to form a composite and subsequently stretching the composite to re-form pores in the substrate. The resulting membrane comprises regions of the ion-conducting material juxtaposed to the gas-permeable pores formed in the substrate by the stretching process.
