In this study, a three‐dimensional model is developed to study a novel proton conducting solid oxide electrolysis cell (H‐SOEC) with porous current collector to alleviate the H₂O‐starvation problem in oxygen electrode. The comparison between conventional straight‐channel structure and the new porous structure is conducted in detail. It is found that the porous current collector can increase the flow uniformity and facilitate the diffusion of H₂O, which in turn improves the average performance of the H‐SOEC. The electrolysis efficiency can be increased by 6.4% compared to straight‐channel structure. It is also found that the thermal neutral voltage is decreased when the porous current collector is adopted. Besides, the evaluation of syngas production for CO₂‐supplied H‐SOEC is performed. Compared to H₂ production, the efficiency of syngas production can be increased by up to 13.5%.

质子传导固体氧化物电解槽的三维建模与性能优化▴

在这项研究中，建立了一个三维模型来研究新型的带有多孔集电器的质子传导固体氧化物电解槽（H-SOEC），以减轻氧电极中的H ₂ O饥饿问题。详细比较了传统的直通道结构和新的多孔结构。发现多孔集电器可以提高流动均匀性并促进H ₂ O的扩散，从而提高H-SOEC的平均性能。与直通道结构相比，电解效率可提高6.4％。还发现当采用多孔集电器时，热中性电压降低。此外，CO ₂合成气生产的评估提供了H-SOEC。与H _2的生产相比，合成气的生产效率可提高高达13.5％。
