Quantum’s Fuel Cell Aggressor


Quantum Technologies (earlier post) has designed, developed and now shipped a high-performance, parallel-hybrid hydrogen fuel-cell off-road vehicle for the US Army.

The Quantum AMVTM (Alternative Mobility Vehicle), nicknamed the “Aggressor,” couples a 10 kW (13.5 hp) fuel cell with a 60 kW (80.5 hp) battery in a parallel hybrid configuration, powering a high-torque (1,681 ft-lbs or 2,280 Nm) electric motor driving the rear wheels.

Preliminary tests show an acceleration from 0 to 60 kmh (37 mph) in less than 4 seconds, and a top speed of 120 kmh (75 mph). Quantum’s electronic control system imposes torque and speed limits on the drivetrain to enhance traction and safety.

The Quantum Aggressor runs on compressed hydrogen stored in Quantum’s proprietary Type IV impact-resistant carbon-fiber storage tanks. The tanks hold 68 liters (2.4 cu.ft) of hydrogen by volume, 1.6 kg (3.53 lbs) of hydrogen by mass.

Type IV tanks are polymer-lined and fully wrapped with fiber composite. Types I through III are fully metal or metal-lined. The Type IV tanks, with plastic instead of metal, are better for weight-sensitive applications (transportation). Traditionally, carbon fiber has a poor resistance to impact damage. Quantum has added a proprietary, impact-resistant shell to the outside of its tanks, which hold up to 10,000 psi (700 bar).

The Aggressor can also function as a silent field generator, providing power for telecommunications, surveillance, targeting, and other battlefield equipment.



This vehicle is awesome. We are now cutting down the pollution in other countries, when will we stop solving other contries proplems for them.
