“…For other thermo‐catalytic microreactors, the physical model should be adjusted accordingly to fit the reaction conditions and kinetics. For electrochemical reactors such as PEMFC and PEM electrolyzers, the physical model should include an additional electrical RN model that is coupled to the fluid network and heat transfer network submodels, combined with appropriate electrochemical reaction models 40 . Then, case‐specific design objectives and constraints need to be incorporated into the establishment of multi‐objective optimization models to complete the scale‐up design.…”

Renewable energy accommodation entails extensive use of modular devices, whose performance degrades remarkably from the lab scale to the industrial scale. This work presents a multi‐objective design optimization approach for modular devices scale‐up as exemplified by hierarchical numbering‐up of reverse water‐gas shift microreactors. The optimization objectives cover a wide span of competing system performance metrics, including the reaction performance, energy efficiency, space occupation, environmental impact, and costs. The decision variables involve the hierarchical geometry, branching, and inter‐stack connection schemes of the microreactor stacks. The obtained Pareto‐optimal designs suggest that multiple short stacks with small intra‐stack distribution channels and large inter‐stack connection tubes can well balance cost and performance. Meanwhile, single‐stack structures with large distribution channels are more suitable for portable applications. The methodology not only can be extended to the numbering‐up of various types of microreactors but also has essential guidance for the integration design of other modular devices.
