2026-06-03 Data Set for Multi-Physics Coupling Simulation of Syngas Production via Co-Electrolysis in a Solid Oxide Electrolysis Stack doi:10.57760/sciencedb.hjs.00716 en [Background]: Co-electrolysis technology based on the solid oxide electrolysis cell for syngas production offers numerous advantages, such as high efficiency and flexibly adjustable H₂/CO ratios, enabling large-scale syngas production with high efficiency and low cost. [Purpose]: To improve the gas-thermal uniformity and stability of the stack during co-electrolysis, it is urgent to investigate the multi-physics coupling behavior of the complete electrolysis stack including inlet/outlet gas manifolds in the co-electrolysis process. [Methods]: Based on COMSOL software, a multi-physics coupled numerical simulation of co-electrolysis was developed on a six-cell solid oxide electrolysis stack. The gas inlet temperature of the electrolysis stack was set to 700 °C, and the cathode-side inlet gas composition (steam : carbon dioxide : hydrogen) was 4 : 4 : 2. [Results]: Distribution data of carbon monoxide concentration field, carbon dioxide concentration field, steam concentration field, hydrogen concentration field, and temperature field under different electrolysis voltages ranging from 6.0 V to 7.8 V were obtained. [Conclusions]: These data provide important support for the subsequent optimization and design of high-reliability co-electrolysis stacks, investigation of failure and damage mechanisms in co-electrolysis stacks, and the operation of co-electrolysis syngas production systems.
