  • Electrochemical cell with a polymer electrolyte and process for producing these polymer electrolytes
    Patent number: 5656386
    Abstract: The electrochemical cell comprises a pair of electrodes (2a, 2b) whose electrode body (3a, 3b) consists of porous base material with a catalyst deposited on carbon particles. Between the electrodes, a membrane film (4) made of a hydrophillic, proton-conducting polymer material is arranged which acts as electrolyte and separator. The material of the membrane film (4) is a base polymer which is radiation-grafted with terminally sulphonated vinyl radicals and is selected from the group formed by substituted and unsubstituted polyolefins, substituted and unsubstituted vinyl polymers and their copolymers, the vinyl radicals being derived from vinyl monomers which are selected from the group formed by substituted and unsubstituted vinyl monomers.
