    摘要： A cathode assembly for use in an electrolyzer cell is provided which comprises at least one separating means adjacent to a face of said cathode assembly and comprising a fluid-impervious material and extending diagonally upwards from a point on a first side of said cathode to a point short of a second side opposite the first side of said cathode, said first separating means having a positive monotonic slope with reference to said first side and to a third side adjacent to said first side and thereby separating said face into at least two interconnected regions. The preferred embodiment of the cathode assembly comprises two separating means equipped with downwardly disposed flanges affixed to an edge of said separating means and extending substantially along the full length of said separating means. A process employing the cathode assembly is also disclosed.
