摘要：Proper upscaling of modular reactors for renewable energy transformation, storage and power-to-fuels/ chemicals, including fuel cells, redox flow cells and micro catalytic/electrocatalytic reactors, is crucial for enabling an economically feasible net-zero-emission future. In this work, we eatablish a multi-objective optimization model for hierarchical numbering-up of modular reactors considering flow uniformity, flow resistance and total device volume as the optimization objectives; the hierarchical topology of reaction channel networks and the geometry of reaction channels and multi-level distributors serve as the decision variables. An evolutionary optimization algorithm is developed to solve the formulated mixed integer non-linear programming problem cost-effectively. Appropriate sizing of primary reaction channels for equipment integration is found to be application-specific. Hierarchical channel layouts are shown to be essential for large-scale applications. Increasing the number of plates per reactor-stack and incorporating reactor-stacks into arrays prove to be superior to the common practice of enlarging individual plates. The proposed approach and the revelation of optimal numbering-up modes under different representative scenarios will enlighten development of systematic design methodologies for a variety of modular devices.
