1. An electrochemical separation device comprising:
a first electrode;
a second electrode;
a cell stack including a plurality of sub-blocks each having alternating depleting compartments and concentrating compartments disposed between the first electrode and the second electrode, each of the sub-blocks including a frame and channel portions;
an internal seal formed of a first material disposed between and in contact with the channel portions between adjacent sub-blocks in the cell stack and configured to prevent leakage between depleting compartments and concentrating compartments in the adjacent sub-blocks; and
an external seal formed of a second material having at least one material parameter different from the first material disposed between and in contact with the frames of the adjacent sub-blocks in the cell stack and configured to prevent leakage from an internal volume of the electrochemical separation device to outside of the electrochemical separation device.
