Abstract: An electrolytic ozone cell that a housing that includes an interfacial seal, a top plate, and bottom plate. The electrolytic ozone cell also includes an internal compartment that having a pair of contact plates, and a tolerance compressor. The tolerance compressor compresses an electrode-membrane-electrode stack that is disposed between the pair of contact plates and the tolerance compressor alters its shape in order to maintain compressive forces on the electrode-membrane-electrode stack.
