GM Hydrogen Fuel-Cell Pickup

GM just gave the U.S. Army a 3/4-ton Chevy Silverado that runs on hydrogen fuel cells.

The good stuff:
Quote:
The all-wheel-drive truck uses the Chevrolet Silverado's production frame and bodywork. Motivation comes from two 94 kW fuel-cell stacks—GM calls them "power modules"—producing a combined 164 horsepower and 317 lb-ft of torque. That's close to the motor torque of 335 generated by GM's 5.3-liter V8 engine. Each module directs electricity to an electric motor, one to drive the front wheels and one for the rear wheels. The truck can operate with just one module and motor. Raise the hood, and the term "engine bay" is immediately discarded. Packed tightly between the fender wells are the drivetrain's cooling radiators, high voltage electrical components and electronic management systems. Under the hood, the only thing common with a conventionally powered pickup is a 12-volt battery that operates the standard auxiliary systems. (Twenty years from now, hot-rodders will have to find something other than chrome valve covers and stainless steel exhaust headers to impress their friends.)

Underneath, the two fuel-cell power modules and three hydrogen storage tanks are tucked between the frame rails, protected by steel skidplates. The truck's standard independent front suspension remains unchanged, while in the rear the live rear axle setup has been replaced by a brawny independent suspension that makes space for the second electric drive mechanism.

The pickup is equipped with a bonus: GM's Quadrasteer four-wheel-steering system. In low-speed driving, the rear wheels steer opposite the front wheels, enabling the big truck to gracefully pull into a tight parking spot as easily as a compact car. At highway speeds, the rear wheels turn in the same direction as the front wheels, providing more stability while changing lanes or passing

i was just learning about hydrogen fuel cells last night in class. they are pretty cool, and the exhaust emitted is only oxygen and water.
