How the FCX Clarity got its name
Honda chose this name to express the idea that the company is creating a fuel cell vehicle that will offer a clear solution to the challenges of the future, helping society achieve sustainable mobility.
How the FCX Clarity works
The FCX Clarity utilises Honda's V Flow stack in combination with a new compact and efficient lithium ion battery pack and a single hydrogen storage tank to power the vehicle's electric drive motor. The fuel cell stack operates as the vehicle's main power source. Hydrogen combines with atmospheric oxygen in the fuel cell stack, where energy from the reaction is converted into electric power used to propel the vehicle. Additional energy is also generated through the capture of kinetic energy from vehicle braking and deceleration (known as regenerative braking), which is stored along with surplus energy from the fuel cell in the lithium ion battery pack, and is used to supplement power from the fuel cell, when needed. The vehicle's only emission is water.
The FCX Clarity's only emission is water. CO2 emissions related to the production of
hydrogen vary by source; however, well-to-wheel CO2 emissions using hydrogen reformed from natural gas - the most widely used method of production today - are less than half that of a conventional petrol vehicle. With the production of hydrogen from water by electrolysis, CO2 emissions can be further reduced and ultimately approach zero if the electricity is generated from sustainable sources, such as solar, wind, hydro and wave power.
In the area of solar technology, Honda has developed its own solar cells, with half the CO2 emissions in the production stage compared to conventional crystalline silicon cells; and has begun mass-production and retail sales of this technology in Japan for both commercial and residential use. These panels are also used to generate electricity for the Torrance R&D refueling station.
