Abstract
Abstract 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 H 2 O‐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 H 2 O, 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 CO 2 ‐supplied H‐SOEC is performed. Compared to H 2 production, the efficiency of syngas production can be increased by up to 13.5%.
Key findings
- The porous current collector increased flow uniformity and facilitated H2O diffusion, improving average performance by 6.4%.
- The thermal neutral voltage decreased with the adoption of the porous current collector.
- Syngas production efficiency increased by up to 13.5% compared to H2 production.
