Abstract
A method of and a sensor for quantitative electroanalytical determination of elemental hydrogen in a fluid medium are disclosed. A membrane enclosed amperometric cell is used that has at least two electrodes in contact with an aqueous electrolyte to provide a reaction impedance of the cell; the electrolyte is separated from the fluid medium by a membrane that is permeable to elemental hydrogen but substantially impermeable to the electrolyte and provides a membrane impedance of the cell; the electrodes include an anodic hydrogen sensing electrode and a cathodic counter electrode; the sensing electrode has a polished surface consisting of a platinum metal; further, the membrane is selected such that the membrane impedance exceeds the reaction impedance sufficiently to provide for membrane-controlled operation of the cell.
