SOLID OXIDE FUEL CELL USING ZEOLITE-TEMPLATED CARBON AS ELECTROCATALYST

A solid oxide fuel cell assembly (SOFC) and a method for making the SOFC are provided. An exemplary method includes forming a functionalized zeolite templated carbon (ZTC). The functionalized ZTC is formed by 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 comprising hydrofluoric acid to form a ZTC, and treating the ZTC to add catalyst sites. The functionalized ZTC is incorporated into electrodes by forming a mixture of the functionalized ZTC with a calcined solid oxide electrolyte and calcining the mixture. The method includes forming an electrode assembly, forming the SOFC assembly, and coupling the SOFC assembly to a cooling system.
