Zusammenfassung:Two-stage systems for oxygen concentration and pressurization. A system includes a first stage oxygen concentrator that receives an input gas and outputs a first oxygen output gas. The system includes a second stage oxygen concentrator comprising a second electrochemical stack, wherein the second stage oxygen concentrator receives the first oxygen output gas and outputs a second oxygen output gas. The first oxygen output gas is stored at a first storage pressure up to a first maximum pressure, the second oxygen output gas is stored at a second storage pressure up to a second maximum pressure, and the second maximum pressure is greater than the first maximum pressure.
