When the New York International Auto Show opens today, the 2003 Honda FCX will be driven on the streets of New York City, making it the first fuel-cell car to do so. The hydrogen-powered Honda FCX is the first and only fuel cell vehicle to date certified by the U.S. Environmental Protection Agency and the California Air Resources Board for every day commercial use. The FCX uses hydrogen supplied to a fuel cell "stack" to generate electricity that powers its electric motor. With 201 foot-pounds of torque, acceleration is similar to a Civic, and the only exhaust is water. As we reported earlier (see the news archives), the City of Los Angeles was Honda's first client for the FCX. Honda began fuel cell research in 1989 and has been road testing vehicles in the United States ever since.
