Fuel Cell
The Chevrolet Equinox Fuel cell vehicle uses hydrogen for fuel with water as its only exhaust. The Equinox Fuel Cell uses the fourth-generation hydrogen technology found in the Chevrolet Sequel concept, which was unveiled in September 2009. The fuel cell is designed for only 50,000 miles (80,000 km) of driving, but is engineered to be operable in subfreezing temperatures throughout its life. GM states that the Equinox Fuel Cell is about 500 pounds (230 kg) heavier than the original Equinox and has one inch less ground clearance. To reduce weight, it has aluminum doors and a carbon fiber hood. It uses headlights from the Pontiac Torrent.
A dashboard mounted screen calculates the fuel savings to that of a gasoline-powered Equinox. It also includes a kilowatt meter and a fuel cell energy display. The fuel cell has four vapor outlets that replace the exhaust pipe. Three carbon-fiber fuel tanks store up to a maximum of 9.25 pounds (4.2 kg) of gaseous hydrogen at 10,000 psi (70 MPa), and give the Equinox a range of 200 miles (320 km). The Equinox Fuel Cell is certified by the EPA as a zero-emission vehicle (ZEV). GM built 115 Chevrolet Equinox Fuel Cell vehicles and deployed them in 2007–2008 in several target areas including New York and California as part of a comprehensive plan dubbed "Project Driveway".

Famous quotes containing the words fuel and/or cell:
“I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.”
—Henry David Thoreau (1817–1862)
“In America all too few blows are struck into flesh. We kill the spirit here, we are experts at that. We use psychic bullets and kill each other cell by cell.”
—Norman Mailer (b. 1923)
