ABSTRACT:
Apparatus and method for performing an electrochemical process involving hydrogen and gaseous compounds capable of dissociating into or combining with hydrogen ions using a solid electrolyte concentration cell. Specific applications are fuel cells for producing an electrical current and separation of hydrogen from a gaseous mixture. A novel solid electrolyte membrane is used which comprises an organic polymer-inorganic compound blend prepared by admixing an organic polymer such as poly(vinyl alcohol) with a phosphoric acid in a mutually miscible solvent. For increased strength, a membrane may be composited with or attached to a porous support. In one embodiment, the membrane may be formed into a hollow fiber having electrically conductive particles with catalyst embedded in the fiber walls; a multiplicity of such fibers may be used to form a hydrogen separation device.
