Fuel-Cell Electric Vehicle Technology Issue Brief
Based on its vision of "Blue Skies for our Children," Honda has worked for more than thirty years at reducing the environmental impact of the automobile, including industry-leading efforts to advance the hydrogen fuel-cell electric vehicle (FCEV) - a technology that Honda believes holds the ultimate promise for a clean and sustainable transportation future. As always, Honda has sought to apply its latest technology in real-world settings and to exceed customers' expectations for performance, quality and safety. Honda's original technology has broken through technical barriers for FCEVs including cold-weather start-up, operating range, efficiency, and compact packaging. Uniquely, Honda is also developing technology to answer the "chicken and the egg" dilemma of the deploying hydrogen-powered vehicles and the refueling infrastructure to support them.
NEXT-GENERATION HONDA FUEL-CELL ELECTRIC VEHICLE TECHNOLOGY
In November 2007, Honda introduced the all-new FCX Clarity - its next-generation fuel-cell electric vehicle that delivers performance, range, efficiency, and style previously unachievable in a FCEV. The FCX Clarity is being leased to retail customers on a regular and continuing basis - the first customer deliveries having taken place in July 2008.
- The FCX Clarity is based on Honda's all-new V Flow fuel-cell electric vehicle platform and is powered by the revolutionary new Honda V Flow fuel cell stack that delivers more power in less space with improved efficiency, power output, driving range, reliability, and cold-weather performance.
- The V Flow stack employs a revolutionary new cell configuration and vertical layout that more than doubles the stack's power-to-weight density versus the previous generation Honda FC stack.
- With the Honda V Flow fuel cell platform, the size of the total powertrain has been reduced by 45 percent to roughly the same size as a V6 hybrid powertrain, while vehicle fuel efficiency is up to an EPA combined city-highway fuel-economy rating of 160 miles per kilogram hydrogen (kg/H2). Based on this increase in efficiency and a 10-percent increase in fuel tank volume, driving range is increased to 240 miles.
- The V Flow platform incorporates a compact and efficient new lithium ion battery pack that is 50 percent smaller and 40 percent lighter than the ultracapacitor in the previous FCX. It marks the first commercial deployment of lithium ion battery technology in an automobile as a source of motive power.
- Honda aims to gain further real-world experience and exposure for advanced FCEV technology with the lease of FCX Clarity fuel cell cars to fleet and retail customers around the world, primarily in North America,.
- Production of the FCX Clarity on the world's first dedicated FCEV assembly line began on June 16, 2008, at Honda's New Model Center, in Takenazawa, Tochigi prefecture, Japan.
- Deliveries of the FCX Clarity to selected retail customers in Southern California began in July 2008.
FUEL CELL ACHIEVEMENTS
Other pioneering achievements in the fuel cell arena include:
First government-certified FCEV: EPA and CARB certified, and certified to meet all applicable federal motor vehicle safety standards (July 2002)
First commercial lease of a FCEV(December 2002)
First FCEV to start and operate in sub-freezing temperatures (2003)
First long-term lease to customers in extreme climates (Las Vegas, New York - 2004)
First FCEV placed in the hands of an individual customer (June 2005)
Lease of FCX to the world's youngest fuel cell customer (March 2007)
Start up of world's first dedicated FCEV and powertrain production facility (June 2008)
- In over five years of use with fleet and retail customers, including government entities in California, Nevada and the state of New York, and retail customers in California, the first-generation FCX has performed well under often harsh conditions, with minimal service support, even in the extreme heat of the Western deserts and the bitter cold of the Northeast.
SOLAR HYDROGEN STATION USING HONDA SOLAR-CELL TECHNOLOGY
Uniquely, Honda is also developing technology to answer the "chicken and the egg" dilemma of the hydrogen-powered vehicle and the refueling infrastructure.
In January 2010 Honda R&D Americas began operating a next-generation prototype Solar Hydrogen Station at its Los Angeles R&D center. The new system is more compact and is designed with an eye toward eventual use as a home refueling appliance, providing convenient and energy-neutral overnight refueling of hydrogen-powered fuel-cell electric vehicles.
This new system no longer requires a compressor, significantly reducing the energy consumed in the refueling process, while providing enough hydrogen, via an 8-hour refuel, to commute 30 miles each day.
The station employs next-generation CIGS thin-film solar cells, developed by Honda Engineering Co., Ltd., and being mass produced and marketed to commercial and residential users in in Japan by Honda subsidiary Honda Soltec, LLC.
1 Official U.S. EPA city/highway combined fuel economy rating. One mile per kilogram of hydrogen (kg-H2) is roughly the equivalent of one mile per gallon (mpg) of gasoline.
