<p>Electrolytic cells are described. The cells comprise the electrolyte K2HPO4, or a less alkaline phosphate buffer solution, electrodes having a modified composition, or a combination of the electrolyte and a modified composition electrode. The K2HPO4 electrolyte, or less alkaline phosphate buffer solution, and modified electrodes can be used in liquid delivery devices which deliver a liquid agent at a constant rate or a controlled variable rate over a period of time.</p> |
