The capabilities of large undersea unmanned vehicles (UUV) for long-range covert missions can be compromised by periodic resurfacing to snorkel depth to recharge, and noise from diesel-electric motors. Giner’s Non Flow Through Fuel Cell eliminates the need for external water management components, and utilizes compact hydrogen storage in the form of solid sodium borohydride. The performance of the fuel cell has been verified in NASA and DARPA programs, and on commercial contracts. In addition, an advanced prototype of the hydrogen storage technology was successfully tested by the Office of Naval Research (ONR). This lightweight, compact, high-density power plant eliminates the need to surface, and is silent. Giner provides electrochemical solutions to the toughest business and operational problems. We seek a partnership with a prime contractor to integrate this system into target vessel designs.
