Project No: FE0000303
The Phase I effort was focused on cell and stack research and development, specifically performance enhancement (power density, fuel utilization, and degradation), cost, and scaling. LGFCS utilized its integrated planar segmented-in-series SOFCs at pressures up to seven atmospheres, as pressurized operation achieves higher volumetric power densities. The Phase I effort also commissioned the requisite cell and stack manufacturing scale and capacity to support follow-on SECA phases. The Phase I deliverable was a ~15 kW SOFC stack comprised of commercially scaled cells and stacks, to be tested for 5,000 hours in accordance with the program minimum requirements (degradation of less than two percent per 1,000 hours [<2%/1,000 h], operating on simulated synthesis gas). Data from this test were used to estimate the performance and cost of the Baseline System.
The current Phase II effort is to deliver a greater than (>) 15 kW SOFC stack incorporating the cumulative technology advancements and developments of the Phase I and II programs. The stack shall be tested in accordance with the guidance provided in the DOE-approved test plan and the SECA Minimum Requirements, and the performance and cost evaluated with respect to the metrics specified therein. The stack deliverable shall be technically and economically viable for aggregation into a greater than or equal to (≥) 250 kW fuel cell power module, which in turn would serve as a building block for a >100 MW IGFC system.
