Abstract: Thin film polymer blend members which may be used for the separation of gases will comprise a blend of an inorganic compound such as phosphoric acid, sulfuric acid, heteropoly acids or salts of heteropoly acids, an organic polymer such as poly(vinyl alcohol) and a poly organic acid such as poly(acrylic acid), poly(methacrylic acid) or poly(styrene sulfonic acid). The thin film membrane composites may be used as gas separation or gas sensor devices.

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 concentraton 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 a three-component blend prepared by admixing an organic polymer, such as poly(vinyl alcohol), with an inorganic comound, such as a phosphoric acid, and a polyorganic acid, such as poly(acrylic acid), in a mutually miscible solvent. For increased strength, a membrane may be composited with or attached to a porous support. In one embodiment, electrically conductive particles with catalyst are partially embedded in the membrane to form a hydrogen separating device.

Abstract: Apparatus and method for detecting and measuring hydrogen and gaseous compounds capable of dissociating into or combining with hydrogen ions using a solid electrolyte concentration cell. A novel solid electrolyte membrane is used which comprises a three-component blend prepared by admixing an organic polymer, such as poly(vinyl alcohol), with an inorganic compound, such as a phosphoric acid, and a poly organic acid, such as poly(acrylic acid), in a mutually miscible solvent. A reference gas or a solid reference substance is used. For increased strength, a membrane may be composited with or attached to a porous support.
