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 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%.
