Monopolar, bipolar, and hydrid filter press electrolytic cells for electrolytic processes utilizing a novel method of introducing and removing electrical energy are disclosed. The invention contemplates a novel low pressure, high surface contact area connecting means for joining the anode element and cathode element of electrode assemblies. The invention also contemplates a low pressure, high surface contact area contact of the current distributor member to the back plate.
