Abstract
The invention relates to a cell of a modular electrolyser having a frame-shaped flange formed by two superposed elements, welded along the internal periphery in order to increase the local flange thickness in a portion of higher exposure to corrosion, for the sake of improving its resistance. A method of repairing electrolysis cells having a frame-shaped flange formed by two superposed elements by removing and replacing only the outermost frame, more subject to corrosion, is also described.
Claims6
Cell of an electrolyser consisting of a modular arrangement of electrochemical cells, said cell comprising at least one pan consisting of a back-wall and a first flange element in form of frame made of a first metallic material, said first flange element integral with said back-wall or alternatively secured thereto, a second flange element in form of planar frame made of a second metallic material fixed to said first flange element, said fixing being a weld localised along the internal edges of said first flange element and said second flange element.
Method of repairing a cell of an electrolyser consisting of a modular arrangement of electrochemical cells comprising a pan consisting of a back-wall and a first flange element in form of frame made of a first metallic material, said first flange element integral with said back-wall or alternatively secured thereto, said first flange element being damaged by corrosion, comprising fixing a second flange element in form of planar frame of a second metallic material to said first flange element, wherein said fixing is a weld localised along the internal edges of said first flange element and said second flange element.
