HIGH CURRENT DENSITY CELL

摘要

A filter press membrane electrolytic cell having at least one cathode and one anode sandwiched about a permselective ion exchange membrane which employs a cathode having a first layer and a second layer cooperative with the membrane such that the voltage cofficient during operation at current densities greater than 4.0 kiloamperes per square meter is less than about 0.20 volts per kiloampere per square meter.
