Investigating the impact and reaction pathway of toluene on a SOFC running on syngas

摘要: Abstract The integration of solid oxide fuel cells (SOFCs) with gasification systems have theoretically been shown to a great potential provide highly efficient distributed generation energy that can be fuelled by biomass including municipal waste. syngas produced from the carbonaceous material is rich in hydrogen, carbon monoxide and methane SOFCs. However, other constituents such as tar cause catalyst deactivation, blockage diffusion pathways. This work examines impact increasing concentrations toluene model typical composition fed NiO-GDC/TZ3Y/8YSZ/LSM–LSM SOFC membrane electrode assembly operating at 850°C atmospheric pressure. Results suggest up 20 g/Nm3 low utilisation factor (c.a. 17%) does not negatively cell performance rather acts increase available hydrogen undergoing reformation. At these conditions deposition occur, detected through EDS analysis, but serves decrease ASR than degrade cell. Alternatively, 32 g/Nm3 66.7% dramatically affected increased which assumed caused deposition. In order test for presence products anode exhaust samples captured using an absorbing filter results HS-GC/MS analysis showing only.
