Abstract
The present invention relates to apparatus and methods of supplying and removing oxygen. The apparatus includes an oxygen-conducting solid electrolyte. The electrolyte has an oxygen input side and an oxygen output side which are each coated with an electrically conducting metallic material. When an electrical potential is applied to the electrolyte, oxygen is caused to move from the input side to the output side. A feedback loop is provided to prevent damage to the electrolyte. Depending on the arrangement of electrolyte, the present invention may provide a source of pure oxygen, including high pressure oxygen, or an oxygen free environment.
