  • Proton conducting polymer membrane for electrochemical cell
    Publication number: 20030012988
    Abstract: A novel proton conducting polymer membrane which contains a network of voids within the membrane is disclosed. Such a membrane allows for a reservoir of additional water within a fuel cell comprising said membrane, such that water electrolysis is sustained in the cell during incidences of cell reversal. Methods for the construction of such a membrane are also provided.
