Analysis and Simulation of an Anode Supported Solid Oxide Fuel Cell Single Channel for Operation with Biosyngas and Methane

A three-dimensional thermo-fluid model coupled with electrochemical reaction for an anode-supported planar SOFC has been developed to investigate the internal processes and temperature distribution within a single cell unit for the design proposed by the Energy research Center of the Netherlands (ECN) in cooperation with TU Delft. The SOFC developed is for operation with natural gas. In this work, operation with biosyngas is evaluated. The electrochemical reactions, heat and mass transfer phenomena between the solid and gas phases have all been included in the cell model. The object is to investigate the complete cell using the models developed and make comparisons for the cell performance when fed with hydrogen, methane and different biosyngas compositions, come up with suggestions for efficient and ideal SOFC operation conditions when fed with different fuels and investigate safety issues under different working conditions. In order to clarify the goals of this work, the following questions have to be answered Is operation with biosyngas safe for the SOFC (Ni oxidation, carbon deposition)? Is operation with methane safe for the SOFC (Ni oxidation, carbon deposition)? What is the impact of different fuel compositions on SOFC performance? What is the impact of the steam reforming reaction of methane on the SOFC performance for operation with biosyngas and methane? What constructive suggestions can be made for further development of SOFCs?
