Electrochemical uses of amorphous fluoropolymers

摘要

An electrochemical application that utilizes amorphous fluoropolymers providing a catalyst coated membrane comprising:
combining a substantially fluorinated non-ionic polymeric ionomer-precursor resin and a catalyst to form a homogeneous mixture;
applying the mixture to the surface of a solid polymer electrolyte membrane to form a coated membrane;
contacting the coated membrane with an alkali metal base to hydrolyze the non-ionic polymeric ionomer-precursor resin forming an ionomer therefrom; and
contacting the ionomer with a mineral acid.
