A porous solid electrolyte (PSE) reactor is a cutting-edge electrochemical device that replaces traditional liquid electrolytes with a solid, permeable membrane to perform chemical synthesis at the interface. It is elaborately designed to produce high-purity chemicals, clean fuels, and drinkable water directly at the point of reaction with great efficiency. This system is specifically designed for the highly selective synthesis of formic acid (HCOOH) via carbon dioxide reduction (CO2RR). This system effectively solves problems related to product separation, electrolyte cross-contamination, and system stability.
The three-chamber system holds the PSE chamber between the cathode and anode chambers, with an AEM and PEM separating the three chambers and supporting reactions in acidic or alkaline environments. Instead of pumping a liquid chemical solution past electrodes, reactants are directly fed through the porous solid electrolyte. The solid structure allows specific ions to pass through while keeping the products separated. It controls the boundary between gas, liquid, and solid phases, allowing gases to diffuse while isolating pure liquid products on the other side and removing the need for purification. The cathode chamber outlet is directly connected to a liquid product condensation and collection device, which can collect and quantify the generated formic acid aqueous solution in real time, facilitating offline analysis (such as HPLC, NMR) and yield calculation.
By eliminating highly acidic or corrosive liquid electrolytes, the system is safer to operate and highly modular, making it easier to stack for industrial-scale production. Advanced PSE configurations allow for simultaneous seawater desalination and hydrogen generation, producing potable water alongside green hydrogen without membrane degradation from salt.
