Abstract
A method of producing an apparatus to remove ions from water is disclosed, wherein the apparatus includes a first electrode having a first current collector, a second electrode having a second current collector, and a spacer between the first and second electrodes to allow water to flow in between the electrodes. The method includes flushing water through the spacer and subsequently exerting a force on the stack so as to compress the first and second electrodes and the spacer. Exerting a force on the stack may result in a pressure of less than 5 bar, less than 2 bar, or between 1 bar and 0.5 bar, between the electrodes and the spacer.
