SECA Core Technology Program - PNNL

This PNNL project will accelerate the development of reliable, low-cost SOFC power generation systems capable of operation on coal derived fuels by developing advanced SOFC component materials and computational tools. Interconnection components for both atmospheric and pressurized operation will be developed. Important to this work is the evaluation and development of materials and manufacturing processes for various SOFC components (electrolyte, anode, cathode, cell-to-cell interconnections, and seals) to support higher performance and robustness, less degradation, and lower cost. In addition, this project will address the effects of coal contaminants on SOFCs and how to mitigate any deleterious effects through upstream clean-up and modification of SOFC components.

This project will also identify, develop, test, validate, and optimize cost-effective cell and stack components, materials, and fabrication techniques; develop advanced computational tools and capabilities for cell and stack design analysis and optimization; test cells exposed to coal contaminants and complete analysis of the results, both post-test and using thermodynamic software; and develop and evaluate new interconnect compositions appropriate for pressurized SOFCs.

Project Benefits

This project focuses on developing and evaluating advanced cell and stack components and computational tools and capabilities for cell and stack design analysis and optimization. Improved cell/stack life and performance will reduce operating cost and increase efficiency, resulting in reduction in the cost of electricity and reduction of CO2 emissions from the entire platform. Specifically, this project will develop, manufacture, and evaluate advanced component materials, manufacturing processes, and computational tools.
