CHAPTER 10: Fuel Cells Running on Alternative Fuels
Published:16 Aug 2013
On the course of ongoing search for alternative energy generation method, solid oxide fuel cells (SOFCs) running on alternative fuels have drawn increasing interest globally due to their high efficiency and critical role in environmental protection. In this chapter, our group’s work in this field is summarized in four categories: (a) In SOFCs using methane containing H2S as the fuel, the doped and composite anodes were developed that showed high sulfur and coking tolerance and high structural stability; the H2S enhancement effect was systematically investigated and the mechanism was explained for the first time. (b) In proton‐conducting SOFCs (PC‐SOFCs) fuelled by C2H6 or C3H8, we modified the proton‐conducting electrolyte and developed the highly selective anode catalysts to have co‐generated electricity and high value‐added products, e.g., C2H4 or C3H6. (c) In SOFCs fuelled by syngas containing H2S, the different anode materials and coking resistant current collectors were developed. (d) SOFCs running on pure H2S improved operation performance by using novel anode materials that we developed.
