Pacific Northwest National Laboratory (PNNL), a U.S. Department of Energy (DOE) laboratory, has worked with government agencies and industrial collaborators to accelerate the commercialization of SOFC power systems for distributed and central power applications. This presentation will highlight work performed for the US DOE Office of Fossil Energy’s Solid Oxide Fuel Cell program. Topics to be covered include effects of contaminants and their mitigation on electrode performance; investigating volatility from cathode materials; improved cell materials; Co-free protective interconnect/BOP coatings development; capabilities of the SOFC stack test platform; and progress on industrial collaborations including seal development in electrolyzer systems fabricated using advanced manufacturing techniques such as 3D printing and rapid electromagnetic sintering.
