This study is particularly aimed at investigating the influence of hydrogen chloride traces in biogas on direct internal reforming solid oxide fuel cells (SOFCs). The experiments are performed with simulated containing methane to carbon dioxide ratio 3:2, usual average proportion biogas. To best our knowledge, there no reported studies that investigated effect by clearly establishing outlet gas composition measurements. SOFC operating temperature 850 °C reveals negative or cell performance, 4, 8, and 12 ppm(v) At 800 °C, visible performance degradation, but a negligible amount (∼ 1%) detected anode off gas. Both electrochemical marginally affected 750 °C. Further, post-test analyses (FESEM-EDS, XRD) used damage microstructure level chlorine poisoning. All context utilizing generated from sewage treatment plants an system. sludge < 10 hence limit set for par this value.
