FY14 Q1 Progress Report for SECA Core Technology Program (open access)

FY14 Q1 Progress Report for SECA Core Technology Program

This quarterly progress report was prepared under field work proposal (FWP) 40552 and covers technical work performed during the period October 1 through December 31, 2013 (FY14 1st quarter). The report highlights and documents technical progress and milestone status in tasks related to advanced cell and stack component materials development and computational design and simulation. Technical highlights related to cell and stack materials development and characterization include: • Surface modified, Ce-modified MC spinel-coated AISI 441 exhibited improved spallation resistance (compared to coated mill reference 441) after 30,000 hours of oxidation at 800ºC in air. Similar beneficial results from surface modification were observed after 26,000 hours of oxidation at 850ºC. • MnCo spinel coatings prepared from metallic powder precursors exhibited low area-specific resistance after 12,000 hours of testing at 800°C. • Long-term validation tests (6,000 hours of operation followed by 10 deep thermal cycles) of surface-blasted, spinel-coated AISI 441 interconnects were completed using PNNL’s SECA CTP stack test fixture. Results of post-test results will be reported in the next quarterly progress report. • Long-term evaluation of compliant glass seals (SCN-1 glass with YSZ fibers) was in progress using PNNL’s SECA CTP stack test fixture. • Baseline testing of LSCF-based cells from …
