Membrane catalyst layer for fuel cells
TL;DR: In this paper, a thin catalyst layer between a solid polymer electrolyte (SPE) membrane and a porous electrode backing is formed by applying an Na+ form of a perfluorosulfonate ionomer directly to the membrane, drying the film at a high temperature, and then converting the film back to the protonated form of the ionomer.
