We work with the Office of Naval Research (ONR) to provide a PEM fuel cell
power system for the U.S. Navy’s Knifefish platform. Our fuel cell system is
scalable for use in all sizes of UUVs or USVs, and provides high energy density
and specific energy compared to conventional battery systems.
In collaboration with ONR, Collins has also developed a system for UUV/USV
fuel cell refueling at sea. Called the refueling and servicing package (RASP),
the system is packaged in a standard ISO container for use on a Navy LCS
platform, and with only distilled water and the ship's power, RASP provides the
servicing required for a UUV fuel cell. Servicing includes refueling the
hydrogen tank, LOX tanks, removal of product water, refilling of DI water and
charging the emergency battery.
