Four advanced development model 1.5kw fuel cell powerplants were delivered to the Army for evaluation. The delivery configuration powerplant weighs 292 lbs. and has a volume of 9.7 cubic feet. Startup and Operation are fully automatic and the powerplant operates on JP-4 fuel with a specific fuel consumption of less than 2.2lbskwh. Output voltage is adjustable from 26 to 34 volts at any output from 0 to 1.5kw. The powerplant consists of four subsystems, a regenerative thermal cracker, which converts logistic fuel to hydrogen, an acid fuel cell powersection which generates dc power from hydrogen and air, a voltage regulator and an automatic control system. A core technology program was conducted to develop the cracker voltage regulator and automatic control unit. Limited development of the powersection, which is based on commercial technology fuel cells, to tailor the design to Army requirements was also conducted. The program culminated with development testing of a complete powerplant and delivery of four powerplants to the Army. Author
