Redox Power Systems, LLC (Redox) together with the University of Maryland Center for Advanced Life Cycle Engineering (CALCE) and the University of Maryland Energy Research Center (UMERC) will develop a high-power density solid oxide fuel cell (SOFC) stack that is reduction-oxidation (red-ox) stable resulting in robust, reliable power systems for lower cost distributed generation. The stacks will be built using an intermediate-temperature SOFC operating at 600-650°C based on an advanced, electrically conductive all-ceramic anode support. The objective of the overall project is to improve the red-ox stability of Redox stacks while reducing costs through the: (1) Scale-up and optimization of all-ceramic anode material processing and cell fabrication for lower cost manufacturing; (2) Determination of all-ceramic anode degradation mechanisms with an optimization of anode compositions and geometries for enhanced red-ox stability of the optimized, robust cells; (3) Demonstration of a 1-2 kW stack that is more robust for red-ox cycling with the use of accelerated, lifecycle, and failure testing; and (4) Demonstration of a 10 percent reduction in system cost and a 30 percent reduction in operation and maintenance (O&M) costs compared by techno-economic analysis to a system without a red-ox stable stack.
