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. |
