A Simulation Study of the Effect of Microstructural Design on the Performance of Solid Oxide Fuel Cells With Direct Internal Reforming

摘要: Abstract >> The paper is to study on the simulation of micro/macroscale thermo-electrochemical model a single cell anode-supported SOFC with direct internal reforming. coupled heat and mass transport, electrochemical reforming reactions, fluid flow were simultaneously simulated based mass, energy, charge conservation. first calculates detailed internalreforming processes in porous electrodes comprehensive microscale then solve macroscale such as SOFCs assumption fully-developedflow gas channel. results evaluate overall performance by analyzing distributions molefraction, current density, temperature microstructural design co/counter configurations.
