Abstract
A polymer electrolyte membrane (PEM) electrolytic cell assembly, and a method for making the assembly, are provided. An exemplary method includes forming a functionalized zeolite templated carbon (ZTC), including forming a CaX zeolite, depositing carbon in the CaX zeolite using a chemical vapor deposition (CVD) process to form a carbon/zeolite composite, treating the carbon/zeolite composite with a solution including hydrofluoric acid to form a ZTC, and treating the ZTC to add catalyst sites, forming the functionalized ZTC. The method further includes incorporating the functionalized ZTC into electrodes, forming a membrane electrode assembly (MEA), and forming the PEM electrolytic cell assembly. The method further includes coupling the PEM electrolytic cell assembly to a heat source.
