Coal-derived syngas offers a compelling pathway for hydrogen-rich fuel production when integrated with solid oxide fuel cells (SOFCs), enabling high-efficiency, low-emissions power generation. This presentation will share recent results from SOFC testing at the Energy & Environmental Research Center (EERC), where long-duration experiments using cleaned coal syngas demonstrated performance and degradation rates comparable to natural gas. The work includes evaluation of syngas cleanup effectiveness, the impact of trace contaminants (e.g., H₂S, AsH₃, PH₃), and findings from contaminant spiking and postmortem analysis. Coupled with multiphysics degradation modeling and techno-economic analysis, the results affirm the viability of coal-sourced fuels for SOFCs under rigorous operational conditions.
