Abstract
An electrochemical separation of oxygen from oxygen containing gaseous mixtures, such as air, using an oxygen containing molten inorganic salt electrolyte retained in a porous matrix between two gas porous catalytic electrodes wherein oxygen is separated from the gaseous mixture when electrical potential is applied across the electrodes providing movement of non-metallic oxygen containing ion from the cathode to the anode.
Claims7
An electrochemical oxygen concentration cell comprising:
- spaced porous electrodes each in contact with an electrolyte on one side and a gas chamber on the other side, said electrolyte comprising oxygen containing molten inorganic salt retained in a porous matrix between two said spaced porous electrodes.
