In this Phase I project, Lynntech proposes to manufacture nanocomposite membranes with significantly reduced hydrogen permeation without adversely affecting the ionic conductivity. This nanocomposite membrane can replace the commercial membranes that are used in the following applications: 1) High pressure PEM electrolyzers to compress the oxygen up to 3,000 psi for EVA, 2) PEM electrolyzers to generate oxygen for environmental control, crew life support, replenishing the oxygen for cabin, pre-breath oxygen delivery unit prior to space walking, propulsion for in-space maneuvering, in-space science activities, 3) Electrolyzers for regenerative fuel cell systems for storing energy in the form of hydrogen and oxygen, 4) Low (up to 50 psi) and high pressure (up to 400 psi) PEM fuel cells for power generation, and 5) Electrochemical oxygen concentrators to concentrate oxygen from cabin air for medical emergencies.
