高温固体氧化物电解水蒸气制氢系统集成放大技术现状与展望OA

Solid oxide electrolysis cell(SOEC)technology offers advantages such as high efficiency and reversible opera-tion,but its scale-up is constrained by the limited power rating of individual stacks,high-temperature operation,and consis-tency issues among multiple stacks.This paper reviews the progress in SOEC system integration and engineering scale-up.Planar,tubular,and flat-tubular configurations and their stacking approaches are compared,and key issues in stack scale-up,including material and interface compatibility,electro-thermal-flow field uniformity,and mechanical reliability,are analyzed.Multi-stack modular integration,thermal manage-ment,balance-of-plant(BOP)configuration,and integration with external heat sources are summarized,together with key enabling technologies such as online diagnostics,balancing control,and lifetime management.The analysis indicates that multi-stack modularization and efficient thermal integration are the principal engineering pathways toward large-scale SOEC systems,while multi-stack operational consistency,the reliabili-ty of high-temperature BOP components,and long-term lifetime management remain critical challenges for further scale-up.
