Direct use of propane and butane in Solid Oxide Fuel Cells(SOFCs) is desirable due to the availability of the fuel source,but is challenging due to carbon coking, particularly on thecommercially available Ni+YSZ anode. A novel dual chamberFlame-assisted Fuel Cell (FFC) configuration with microtubular SOFCs (mT-SOFCs) is proposed for direct use of higherhydrocarbon fuels. Combustion exhaust for propane and butanefuels is analyzed experimentally and compared with chemicalequilibrium. mT-SOFC polarization and power density testingin the FFC configuration with propane and butane fuels isdiscussed. Peak power and electrical efficiency conditions areassessed by varying the fuel-rich combustion equivalence ratioand flow rate. Carbon deposition and soot formation on theNi+YSZ anode is investigated with a scanning electronmicroscope. The results indicate that reasonable power density(~289 mW.cm-2) can be achieved while limiting soot formationin the flame and carbon deposition on the anode. Electricalefficiency based on the higher heating value of the fuels isanalyzed and future research is recommended. Possibleapplications of the technology include small scale powergeneration, cogeneration and combined cycle power plants.
