US Army Labs at Fort Belvoir,
US Army Labs at Fort Belvoir, VA demonstated hydrazine fuel cells in the 1960's. A 300 watt units was field tested in Viet Nam and a 20 k/W unit powered a military type pick up truck. The goal always was to use logistic fuels which were clearly far into the future. Hydrazine hydrate fuel cells allowed testing of systems using electric power source to provide a basis for hydrocarbon fuel cell research.
