A hybrid redox-halogen energy storage device and system has a housing divided into two chambers by a microporous separator. Each chamber can contain an electrolyte such as CrCl.sub.3. The microporous separator keeps the C.sub.r.sup.+2 ion in the chamber containing the negative electrode and also keeps chlorine gas (Cl.sub.2) in the positive electrode chamber.

Metal-halogen energy storage device and system

A hybrid redox-halogen energy storage device and system has a housing divided into two chambers by an anionic membrane. One chamber has an inert negative electrode in an electrolyte solution containing chromium ions. The remaining chamber has an inert positive electrode containing chlorine gas dissolved therein. Each electrolyte is circulated to a separate storage tank after passing through its respective chamber.

Chrome-halogen energy storage device and system

A method for potentiometric detection of hydrogen peroxide including providing an electrolytic cell having a working electrode and a reference electrode. The working electrode is composed of a hydrogen peroxide sensitive material and also is employed as a support for an oxidase enzyme. Introducing a hydrogen peroxide releasing substance into the cell and releasing the hydrogen peroxide by effecting interaction with the enzyme. Developing in said cell an electrical potential which is a function of the concentration of the hydrogen peroxide and measuring the electrical potential of the cell. The method may be employed as a quantitative glucose detector by employing as the enzyme or enzymes glucose oxidase with or without catalase. Apparatus for potentiometric determination of hydrogen peroxide includes a cell containing an electrolyte, a working electrode and a reference electrode. An electrometer is operatively associated with the electrodes. The working electrode is composed of a material which will create an electrical potential when it interacts with hydrogen peroxide. At least one oxidase enzyme is immobilized on the working electrode.
