A method for producing a catalyst-coated polymer membrane for an electrolyser and/or a fuel cell includes steps including providing a glass-ceramic substrate and synthesizing a mesoporous catalyst layer on the glass-ceramic substrate. The steps include pressing a polymer membrane onto the glass-ceramic substrate coated with the catalyst layer at a first temperature T.sub.1, thereby producing a sandwich structure. The steps further include separating the sandwich structure. The catalyst layer is separated from the glass-ceramic substrate and adheres to the polymer membrane.

Described, herein, relates to a fluorinated electrocatalyst and a method of optimizing a catalytic reaction within an electrochemical cell, in which fluorine atoms may be introduced to the local coordination environment sites to weaken the carbon-nonmetal bonds and drive the nonmetallic chemical elements towards metallic chemical elements. The method may include introducing fluorine atoms to the metal-nonmetal-carbon catalysts to occupy the LCE site within the catalysts in order prevent the nonmetallic chemical elements from occupying the LCE sites, thereby driving the nonmetallic chemical element to form a nonmetallic chemical element layer on a surface of the metallic chemical elements. The nonmetallic chemical element layer may also inhibit the agglomeration and migration of the metallic chemical elements about the LCE site, optimizing catalyst activity through the regulation of the LCE site. The resulting fluorine-doped high-performance catalysts may be usable within electrochemical cells, with long-term stability and reduced degradation.
