The Technology
Separation of oxygen from ambient air is currently done using cryogenic and sorption processes. Although the present technology is very common and currently most of the oxygen is being produced using these methods, cryogenic and sorption processes are high energy demanding, partially due to their low efficiency as well as due to the ultra-low temperatures and high pressures used in the cryogenic process and due to the large regeneration costs needed in the sorption process.
Electrochemical based processes are well known as highly efficient. It was shown that simple non-corrosive solid state electrochemical cell using low-cost electrodes and polymeric membranes can be used to separate oxygen from gas mixtures, including separation from ambient air at room temperature and low voltages.
The mild operating conditions allow a safe and affordable method to produce clean oxygen on-demand.
