Performance characterization and modelling of syngas-fed SOFCs (solid oxide fuel cells) varying fuel composition

摘要: SOFCs (solid oxide fuel cells) are a promising technology for electric power generation, because of their high efficiency and flexibility. Relative to more mature technologies, they appear very competitive starting from small-scale applications. The aim this study is map SOFC performances varying composition, reproducing gases technical interest (biomass air oxy-gasification, water carbon dioxide co-electrolysis, steam methane reforming) provide forecasting tool predict performance upon the composition occurring in any application. Therefore, at first commercial tested using several gas mixtures produced by means chosen technologies (H2, CO, CH4 molar fractions ranges respectively 8–50%, 0–42%, 1–8%). Secondly, experimental data used build mathematical characteristic curve composition. This result interesting point view system-level modelling, it allows characterizing many Forecast error less than 1%. Because its accuracy, model can be implemented assess properly as consequence particular hybridization, whereas falls into range already defined.
