Addressing Environmental Issues With Fuel Cell Vehicles
As part of its initiative to reduce the environmental impact of automobiles, Honda is making cleaner and more environmentally responsible vehicles.
Honda has always been proactive and innovative in its approach to the reduction of atmospheric pollution. With the introduction of the CVCC engine in 1972, Honda became the world's first automaker to comply with the stringent exhaust emissions regulations of the 1970 US Clean Air Act without the use of a catalytic converter. And, Honda has continued to work to improve the emissions performance of all its vehicles. Addressing the problem of global warming, Honda has worked to reduce CO2 emissions by improving the fuel efficiency of its gasoline engines, introducing a world-class natural gas-powered vehicle, and developing hybrid vehicles and next-generation clean diesel-powered automobiles.
The ultimate expression of the electric vehicle concept: how Honda's fuel cell vehicle works
A fuel cell vehicle has a hydrogen tank instead of gasoline tank. In the fuel cell, hydrogen is combined with atmospheric oxygen to generate electricity. The fuel cell is more like a tiny electric power station than a battery. Since the electricity required to power the vehicle's motor is generated onboard using hydrogen and atmospheric oxygen, no CO2 or other pollutants are emitted in this process. It's the ultimate in clean performance - its only emission is the water produced as a byproduct of electricity generation. A compact and efficient lithium ion battery stores electricity generated during braking and deceleration in regenerative braking. The battery works in concert with the fuel cell stack to power the vehicle.
