Rapidly Throttleable Oxygen Generation Using Microwave Plasma Decomposition of Rod Fed Perchlorates

Elimination of high pressure and cryogenic propellant storage and feed systems for undersea vehicle fuel cells is of interest to the Navy. CFDRC proposes the development of a rechargeable oxygen generator based on microwave plasma decomposition ofsolid-state lithium perchlorate. The generator will employ the atmospheric microwave plasma torch technology recently demonstrated by the Plasma Science and Fusion Center at MIT. The main advantages of the proposed plasma technology are: electrodelessoperation, high throughput atmospheric processing which meets the needs of a wide power range of fuel cells (50W - 5kW), microwave-to-plasma coupling efficiencies approaching 100%, and the utilization of an inexpensive and reliable microwave source. Theproposed generator configuration will exceed all underwater vehicle operational requirements: high oxygen content, silent operation, rapid oxygen rate throttleability, and scalability. The key technology is an innovative circular microwave waveguidecombined with a unique hollow-rod perchlorate feed system.During Phase II CFDRC will work with MIT to optimize the plasma-based oxygen generator prior to delivery to the Navy for independent test and evaluation. CFDRC''s mature working relationships with General Motors, Siemens and other equipment manufacturers assures rapid commercialization of this system into underwater and land based fuel cell powered vehicles. CFDRC''s mature working relationships withBoeing, LockMart, and NASA offers immediate technology infusion into numerous in-space applications. Our presence in the fuel cell and plasma technology communities (www.cfdrc.com/applications) assures access to numerous other commercial and militarybusiness opportunities.
