Project Description

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.

Project Benefits

The Redox project goal is to develop a cost-effective SOFC stack with improved performance and durability that is the platform for distributed generation systems such as the Redox Cube - currently designed for 25 kW of natural gas fueled power generation.
