A method of producing an electrolyte membrane includes providing a dispersion solution that has a crosslinked perfluorinated ionomer material and a linear perfluorinated ionomer material dispersed in a carrier fluid or mixture carrier fluids. The crosslinked perfluorinated ionomer material has an equivalent weight of 750 g/mol or less with respect to proton exchange acid groups. The linear perfluorinated ionomer material has an equivalent weight of 750 g/mol or more with respect to proton exchange as acid groups. At least a portion of the carrier fluid or fluids is removed from the dispersion solution to thereby form an electrolyte membrane with the crosslinked perfluorinated ionomer material and the linear perfluorinated ionomer material.
