ABSTRACT:
Microporous separators for electrolytic cells are fabricated from multiple fluoropolymer panels joined and sealed together so as to conform with cell geometry. Improved, leak-free seals are made in the case of chemically treated separators by applying a non-melt processable perfluoroalkylene polymer sealant between separator joints which are then sealable by application of heat and pressure. Only damaged sections or "worn" panels of cell separators need be replaced by resealing new panels to previously heat sealed edges of non-damaged separator sections by application of the polymer sealant. The sealant is one having melting or fusing temperature which is at least substantially equivalent to the melting or fusing temperature of the polymeric microporous separator.
