<p>A bipolar electrode comprising (a) an anode member comprising a substrate made of an anticorrosive metal or metal alloy and an electrically conductive coating formed on the surface thereof; (b) a cathode member comprising a metal or a metal alloy; (c) a partition wall for separating the anode member from the cathode member, the partition wall comprising an anodeside sheet made of the same type of anticorrosive metal or metal alloy used as the substrate of the anode member and a cathodeside sheet made of the same type of metal or metal alloy used as the cathode member; and (d) a composite member for electrically and structurally connecting the anode member and the cathode member to each other, the composite member comprising bonded together (i) an anodeside portion made of the same type of anticorrosive metal or metal alloy used as the substrate of the anode member, (ii) a cathodeside portion made of the same type of metal or metal alloy used as the cathode member, and (iii), as an interlayer, a portion made of an electrically conductive metal or metal alloy, which is resistant to the migration of hydrogen and is substantially impermeable to atomic hydrogen, wherein (1) pins made of an electrically conductive metal or metal alloy, which is resistant to the migration of hydrogen and is substantially impermeable to atomic hydrogen, are caulk-fitted in through-holes provided in the composite member (d), the through-holes outwardly diverging toward both surfaces of the composite member (d) so that the pins (1) adhere closely to the inside surfaces of the through-holes in the composite member (d), (2) the anode-side sheet and the cathode-side sheet of the partition wall (c) are sheets having no throughholes for inserting the composite member.</p> |
