Effect of the Reactant Transportation on Performance of a Planar Solid Oxide Fuel Cell

The process of reactant transportation greatly affects the performance solid oxide fuel cells (SOFCs). Therefore, a three-dimension numerical SOFC model was built to evaluate mainly effect coupling heat and mass transfer electrochemical reactions, reliability calculations validated. Numerical studies revealed correlation both increase concentration gradients improved capability multi reactants in gas diffusion electrode with enhancement performance, condition enough supplies oxidant. Further identified oxygen ions conductivity electrolytes played critical role energy output thus SOFCs. For example, current density would by 65% if ionic doubled. This study gives insight into significance operational conditions, electrolytes, structures on further optimization Overall, modeling leads clear path toward
