1. A method of forming a polymer electrolyte membrane, the method comprising:
forming a reaction mixture comprising a macromolecular chain transfer agent, an ionic component, a monofunctional monomer, and a di- or greater functional monomer;
simultaneously crosslinking and polymerizing the monomers in the reaction mixture to form a polymer electrolyte membrane having co-continuous domains comprising a conductive phase and a crosslinked network phase, wherein the crosslinked network phase is formed from the monofunctional monomer and di- or greater functional monomer.
