Quantum Fuel Systems Technologies Worldwide, Inc. has received a multi-million dollar purchase order from GM for hydrogen-storage systems to be used in GM’s recently announced Chevrolet Equinox Fuel-Cell vehicle program. (Earlier post.)
GM will begin building and deploying a 100-vehicle fleet of Equinox Fuel-Cell vehicles in 2007. The 10,000 psi (70 MPa, 700 bar) hydrogen storage systems for these Equinox Fuel-Cell vehicles are based on Quantum’s Type IV (polymer-lined, all-composite) ultra-lightweight tank technology, incorporating advances in materials, material utilization, and optimized design, yielding benefits proprietary to GM. (Earlier post.)
These hydrogen storage systems are fully integrated modules comprising three 10,000 psi tanks that together store 4.2 kg (9.24 lb) of hydrogen. The systems incorporate Quantum’s proprietary high-pressure valves, regulators, and safety systems. Quantum designed, developed, and safety tested these systems specifically for this GM vehicle program.
The Equinox Fuel Cell is powered by a fourth-generation, 93kW fuel-cell stack. The stack will operate in temperatures ranging from 13° F to +113° F (-25° C to +45° C). A 35kW NiMH battery pack supplements the fuel cell and captures energy from regenerative braking. The 3-phase asynchronous electric motor generates 73 kW of continuous power (94 kW maximum) and torque of 320 Nm (236 lb-ft).
The Equinox Fuel Cell accelerates from 0-60 mph in 12 seconds; has a top speed of 100 mph (160 kph); and has an operating range of 200 miles (320 km).
