ABSTRACT:
A combination seal and tentering member suitable for use as a gasket in an electrolytic cell of the filter press type and suitable for tentering a membrane used in the electrolytic cell. The seal/tentering member used in the filter press type electrolytic cell includes a first portion generally rectangular in cross section, having parallel top and bottom walls and first and second vertical parallel side walls, and a second flange portion integral with the first portion generally rectangular in cross section having a top and bottom wall and first and second parallel side walls, said second portion having top and bottom walls of a smaller length such that the seal/tentering member forms a "P-shaped" parameter viewed in cross section, said bottom of first portion and top of second portion being a contiguous boundary and said first side wall of said second portion and said first side wall of said first portion is substantially the same wall. Aqueous alkali metal chloride solution may be electrolyzed in the electrolytic cell.
