Internal steam reforming in solid oxide fuel cells: Status and opportunities of kinetic studies and their impact on modelling

摘要: Solid oxide fuel cells (SOFC) systems with internal steam reforming have the potential to become an economically competitive technology for cogeneration power plants, exploiting its significantly higher electrical efficiency compared existing technologies. Optimal design and operation of such a system require SOFC models that include accurate description rate. The objective this article is review reported kinetic expressions reaction. Extensive work has been performed on traditional catalysts reforming. Because differences in operating conditions, catalyst support material structure it critical transfer knowledge directly SOFCs, which discussed further detail article. There are big expression over both industrial Ni anode materials. Surprisingly, there good agreement between measured rates pr. geometric area at high temperatures, even very different anodes. Detailed experimental data intrinsic kinetics Ni-YSZ necessary micro modeling, however lacking, but may be viable use measurements instead. Nevertheless need studies determining exact
