  • Proton conducting polymer membrane for electrochemical cell
    Patent number: 7052792
    Abstract: A novel proton conducting polymer membrane comprising a series of channels and/or capillaries (2) for use in MEAs and fuel cells is provided. Such a membrane allows a supply of water from an external source to be supplied to said membrane allowing water electrolysis to be maintained during incidences of cell reversal in an MEA or fuel cell comprising said membrane. Methods for the construction of such a membrane are also provided.
    Type: Grant
    Filed: March 16, 2001
    Date of Patent: May 30, 2006
    Assignee: Johnson Matthey Public Limited Company
    Inventors: John Malcolm Gascoyne, Thomas Robinson Ralph, Graham Alan Hards

  • 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.
