Japan's third biggest automaker expects to lease out a "few dozen" units this year and about 200 units within three years. In California, a three-year lease will run $600 a month, which includes maintenance and collision coverage.
Among the first customers are actress Jamie Lee Curtis and filmmaker husband Christopher Guest, actress Laura Harris, film producer Ron Yerxa, as well as businessmen Jon Spallino and Jim Salomon.
"It's so smooth," said Harris, who played villainness Marie Warner on the hit TV show "24" and was flown over by Honda for the ceremony. "It's like a future machine, but it's not."
The FCX Clarity is an improvement of its previous-generation fuel cell vehicle, the FCX, introduced in 2005.
A breakthrough in the design of the fuel cell stack, which is the unit that powers the car's motor, allowed engineers to lighten the body, expand the interior and increase efficiency, Honda said.
The fuel cell draws on energy synthesized through a chemical reaction between hydrogen gas and oxygen in the air, and a lithium-ion battery pack provides supplemental power. The FCX Clarity has a range of about 270-miles per tank with hydrogen consumption equivalent to 74 miles per gallon, according to the carmaker.
The 3,600-pound vehicle can reach speeds up to 100 miles per hour.
John Mendel, executive vice president of America Honda Motor Co., said at a morning ceremony it was "an especially significant day for American Honda as we plant firm footsteps toward the mainstreaming of fuel cell cars."
The biggest obstacles standing in the way of wider adoption of fuel cell vehicles are cost and the dearth of hydrogen fuel stations. For the Clarity's release in California, Honda said it received 50,000 applications through its website but could only consider those living near stations in Torrance, Santa Monica and Irvine.
Initially, however, the Clarity will go only to a chosen few starting July and then launch in Japan this fall.
California Gov. Arnold Schwarzenegger has called for a statewide network of hydrogen stations, but progress has been slow.
The state has also recently relaxed a mandate for the number of zero-emission cars it aims to have on roads. By 2014, automakers must now sell 7,500 electric and hydrogen fuel cell vehicles, a reduction of 70 percent.
Spallino, who currently drives Honda's older FCX and was also flown in for the ceremony, said he will use the Clarity to drive to and from work anle car.
The company has not revealed how much each car costs to make, and it is unclear when, or if, the car will be available for mass-market sales. Takeo has set a target for 2018, but meeting that goal will depend on whether Honda can significantly lower development and assembly costs as well as market reaction to fuel cells.
