Effect of gas flow rates and Boudouard reactions on the performance of Ni/YSZ anode supported solid oxide fuel cells with solid carbon fuels

► Lower carrier gas flow rates enhanced the cell performance of carbon-based solid oxide fuel cells (C-SOFCs) by increasing the extent of electrochemical oxidation of CO due to the long residence time of CO. ► The power generation from C-SOFCs can be further increased by increasing gasification rate of solid carbon via Boudouard reaction. ► CO and CO2 can displace adsorbed hydrogen on the solid carbon fuels of C-SOFCs.
