An electrode comprising a pulverulent electroconductive, electrocatalytic material bonded together with a fluoroolefin polymer having a hydrophilic surface.
An electrode-membrane comprising a thin sheet of an ion-exchange membrane having bonded to one side thereof a layer of a pulverulent electro-conductive, electrocatalytic material bonded together with a fluoroolefin polymer having a hydrophilic surface, wherein the hydrophilic surface is obtained by exposing the polymer to ionizing radiation from a Cobalt 60 source with a radiation dose from 10 to 400 Megarad in the presence of a precursor substance of hydrophilic groups.
An electrolysis cell containing at least one cathode and at least one electro-membrane comprising a thin sheet of an ion-exchange membrane having bonded to one side thereof a layer of a pulverulent electro-conductive, electrocatalytic material bonded together with a fluoroolefin polymer having a hydrophilic surface, wherein the hydrophilic surface is obtained by exposing the polymer to ionizing radiation from a cobalt 60 source with a radiation dose from 10 to 400 Megarads in the presence of a precursor substance of hydrophilic groups.
