The University of Connecticut will develop low-cost alloy anodes for distributed internal reforming of methane and other hydrocarbon fuels to potentially increase the fuel-flexibility, reliability, and endurance of solid oxide fuel cells (SOFC). The project will modify chemical compositions and microstructures of high-entropy alloy (HEA) anode materials via thermochemical calculations, process simulation, and modeling analysis to achieve distributed reforming over the entire anode and thus eliminate hot zones; model and predict carbon formation over the anode to achieve coke-free anodes using density function theory; fabricate cells and test the HEA anodes using a button cell configuration to demonstrate their advantages over traditional Ni-YSZ anodes for distributed reforming for long-term stability; and scale up the synthesis of HEA anode materials and cell fabrication for industry applications.
