This proposal builds on preliminary work, performed in 2012, which demonstrated that plasma treatment methods can effectively modify the wetting characteristics of various porous metal structures. Such structures are critical to the two-phase fluid separation processes used in non-flow-through fuel cells and static feed electrolyzers. Optimization of these structures is the key to achieving dramatic reductions in the complexity and mass of regenerative fuel cells (RFCs).
The objective of this proposal is to further define the potential for plasma treatment technology, developed by the NASA Glenn Research Center (GRC) to modify and enhance the wetting characteristics of water management surfaces. If successful, such enhancements will lead to more robust operation and reduced system complexity. Methods which promote both hydrophilic and hydrophobic character will be explored.More »
High efficiency, and long-life, regenerative fuel cells are required for the large scale energy storage needs of future SMD and ARMD missions. Results could also benefit electrolyzers for onboard oxygen generation. NASA’s Human Spaceflight Architecture Technology (HAT) has determined that it is critically important to develop renerative fuel cells (RFC) systems for surface power and to develop fuel cell power systems for the cryogenic propulsion stage (CPS). In addition, they determined that the multi-purpose crew vehicle, the deep space habitat (DSH), and any lander would benefit from advanced fuel cell and electrolyzer technology.More »
