摘要
The present study reports a systematic computational analysis of the performance of solid oxide metalair redox battery operated at 800 and 550 ℃ using a recently developed high-fidelity multiphysics model.Two sets of parameters are particularly investigated:(1) operational parameters including current density and depth of discharge;(2) performance parameters including the chemical reaction kinetic rate constant of the redox cycle unit and exchange current density of the regenerative solid oxide fuel cell.These two groups of parameters are particularly analyzed with the goal to achieve high specific energy and round trip efficiency for SOIARB operated at different operating temperatures.
The present study reports a systematic com- putational analysis of the performance of solid oxide metal- air redox battery operated at 800 and 550℃ using a recently developed high-fidelity multiphysics model. Two sets of parameters are particularly investigated： （1） opera- tional parameters including current density and depth of discharge; （2） performance parameters including the chemical reaction kinetic rate constant of the redox cycle unit and exchange current density of the regenerative solid oxide fuel cell. These two groups of parameters are par- ticularly analyzed with the goal to achieve high specific energy and round trip efficiency for SOIARB operated at different operating temperatures.
