Investigation of Metals Corrosion in SOFCs Using Raman Spectroscopy (PNNL Scope # 40552 SOFC Interconnects)
EMSL Project ID
16707
Abstract
Objectives:The objectives of this task to:
• Use the Raman spectroscopy to investigate carbon dusting on SOFC interconnect candidate alloys
• Understand the carbon dusting and corrosion behavior of the interconnect candidate alloys under the SOFC operating conditions.
Approach:
• Test interconnect candidate alloys, e.g. Crofer22 APU under a hydrocarbon fuel and the air||fuel dual environment at 800oC for 1,000 hours. In this work, a reformate will be used as a representative of the hydrocarbon fuel.
• Study the tested samples first by surface X-ray diffraction effects, and then by the Raman spectroscopy.
• Investigate the tested samples further by SEM analyses on the surface and cross-sections of the samples. TEM can be option, depending on the outcome and the completeness of previous analyses.
