Doing away with membranes from the chloralkali process
Cost-effective and scalable electrochemical cells rely on inertial separation mechanism, rather than membranes, to keep products separate
A new 3D printed flow electrolysis cell developed in Switzerland can produce hydrogen and oxygen from water, and commodity chemicals from brine, without a membrane. The system is a significant advance for membrane-less architectures in terms of output, and a step towards the direct conversion of excess renewable electricity into useful chemicals.
