Abstract
Ceramic honeycombs made of a ceramic material of a solid electrolyte nature having at least some of the honeycomb channels sealed at one of the faces are useful for the concentration or separation of oxygen from air or other oxygen-containing gaseous mixture. The oxygen-containing gas is introduced into a first set of channels at one face of the honeycomb, a first voltage is applied to the interior walls of those channels, and a second voltage applied to the interior walls of the second set of remaining channels, thereby creating an electrical potential across the ceramic material separating any adjacent channels of the two sets. The electrical potential drives oxygen ions through the channel walls releasing concentrated oxygen into the second set of channels for collection therefrom.
