China Changan Automobile in 2007 completed the first efficient zero-emission hydrogen internal combustion engine ignition, and independent research and development of China's first hydrogen-powered concept car "hydrogen process on display at the 2008 Beijing auto show."
"Car society" gradually formed, cars are constantly on the rise, oil and other resources are stretched, on the other hand, swallow large amounts of gasoline in vehicles emit harmful gases and pollutants. The ultimate solution, of course not to limit the development of automobile industry, but to open new energy alternative to oil, fuel cell vehicles of the four quickly and quietly rolling across the road, almost exactly the printed name of the new energy - hydrogen.
Almost all of the world's auto giants in the development of new energy vehicles. The electricity had been considered to be the future power of the car, but the lengthy battery charging time and the weight of the people gradually it dull. Current (referring to 2009), hybrid and gasoline combination can only temporarily alleviate the energy crisis can only be reduced but can not get rid of dependence on oil.
This time, the emergence of the hydrogen-powered fuel cell, like recycling a Noah's Ark, so that people see from the crisis of infinite hope. Hydrogen as a fuel for vehicles this statement just come out to surprise, but in fact is. Hydrogen has a high energy density, the energy released is sufficient to make the car engine running, and the hydrogen and oxygen in the fuel cell chemical reaction generates only water, no pollution.
Therefore, many scientists predicted, hydrogen energy, fuel cell car of the 21st century core technology, the revolutionary significance of its automotive industry, which is equivalent to the microprocessor of the computer industry as
Emissions of hydrogen-powered cars is pure water, the driving does not produce any pollutants. However, the high cost of hydrogen fuel cell, hydrogen fuel storage and transportation in accordance with the present technical conditions very difficult, because the hydrogen molecules is very small, easily escape through the shell of the storage device.
The most fatal problem, hydrogen extraction needs through the electrolysis of water or the use of natural gas, also need to consume a large amount of energy this way, unless the use of nuclear power to extract, otherwise it is impossible to radically reduce carbon dioxide emissions.
