NESC Ceramic Oxygen Generator (COG) Technology Development
Abstract
The NASA Engineering and Safety Center (NESC) sponsored a project to accelerate the pace of technology development of a ceramic oxygen generator (COG), for NASA and COVID related medical use. NASA applications for this technology include spacesuit oxygen tank recharge, medical applications include providing medical oxygen in remote and low resource settings. During this project, five full-scale (i.e., 30 wafer) cell stacks were built and tested in prototype systems capable of producing pressurized oxygen. System testing measured oxygen product purity, delivery pressure, production rate, and energy use. This report describes ion transport membrane mechanisms, cell stack configuration, and test results.
