Presently, Europe is faced with the task of implementing the Columbus Space Program. In a stepwise approach the Columbus Initial Orbital Configuration will involve eventually into a European (permanently) Manned Space Infrastructure. Towards this goal, various technological challenges arise for the Environmental Control and Life Support System (ECLSS). Some of these have already been identified and are subject of initial investigations. To regain oxygen from the metabolic process, a physico-chemical chain of CO2-concentration, CO2-cracking and water electrolysis is under development. The present status of the preliminary breadboarding, composed of a steam desorbed solid amine concentrator and a Sabatier reactor will be discussed. The third item in this chain, the electrolyser, is not yet implemented in this breadboarding but is under test, demonstrating the technology for regenerative fuel cell application.
