The fuel cell electric vehicle (Fuel-Cell) using hydrogen and oxygen in the air under the action of the electric energy by an electrochemical catalyst reaction generated in the fuel cell, as the main power source and the vehicle driver.
1. What is FCV
The fuel cell electric vehicle is essentially an electric vehicle, the vehicle body, the power transmission system, control system, fuel cell electric vehicles and general electric car is basically the same, the main difference is the working principle of power battery.
In general, a fuel cell by an electrochemical reaction of the chemical energy into electrical energy, the desired electrochemical reaction of hydrogen reducing agent is generally used, the oxidizing agent with oxygen, so the earliest development of the fuel cell electric vehicle mostly used directly hydrogen fuel, hydrogen gas can be liquefied hydrogen is stored, compressed hydrogen or metal hydrides like.
(Audi Q5Fuel-Cellhybird, Benz B Fuel-Cell) further comprises a dual fuel cell vehicle.
having two fuel supply system, a supply of natural gas or liquefied petroleum gas, another set of fuel supplied to the other,Two fuel supply system supplying fuel to the combustion chamber in a predetermined ratio, mixing the combustion in the cylinder of the car, such as diesel – compressed natural gas dual fuel vehicles, diesel – LPG dual-fuel vehicles and other such vehicles. .
2 FCV disadvantages which
· advantages of pollution reduction, strong economic: the use of clean gasoline cars, emissions of hydrocarbons (the HC), carbon monoxide (CO ), nitrogen oxides (NOx) will be greatly reduced, good for everyone.
· fuel: improved fuel system clean, the degree of atomization of oil, the mixture is completely burned, maximize power.
– to improve the running performance: to start the engine, speed stable, good acceleration performance.
· ride comfort.
· security is better.
· disadvantages not very mature technology, compared with other fuel cells, more complex structures.
