Membrane electrode assembly and method of its manufacture
TL;DR: In this paper, a method for making a membrane electrode that employs a composite membrane, which includes both a porous membrane and an ion conducting electrolyte, by partially filling the porous membrane with an ion-conducting electrolyte to form a partially filled membrane and then compressing the partially-filled membrane with electrode particles so as to remove void volume from the partiallyfilled membrane and embed the electrode particles in the partially filled membranes.
