    H2 FC technology could augment ships and subs on patrol

    GM, the Office of Naval Research and the U.S. Naval Research Laboratory are cooperating to incorporate automotive hydrogen fuel cell systems into the next generation of Navy unmanned undersea vehicles, or UUVs.

    Hydrogen fuel cells convert high-energy hydrogen efficiently into electricity, resulting in vehicles with greater range and endurance than those powered with batteries. Under the ONR’s Innovative Naval Prototype program for Large Displacement UUVs, energy is a core technology in the Navy’s goals for vehicles with more than 60 days endurance.

    The Naval Research Laboratory recently concluded an evaluation of a prototype UUV equipped with a GM fuel cell at the heart of the vehicle powertrain. The tests, a key step in the development of an at-sea prototype, were conducted in pools at the Naval Surface Warfare Center in Carderock, Md.

    Frank Herr, ONR's department head for Ocean Battlespace Sensing:
    H2 FC propulsion technology helps address two major automotive environmental challenges: petroleum use and CO2 emissions. Fuel cell vehicles can operate on renewable H2 from sources like wind and biomass stored for later use. Once converted to electricity, water vapor is the only emission. Recharging takes only minutes.

    GM’s fuel cells are compact and lightweight, and have high reliability and performance. Lower cost is achievable through volume production. These attributes match the goals of the Navy to develop reliable, affordable systems.
