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 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. 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.
