As the most easily available energy source, hydrogen energy has gained a higher position in fuel cells. With the emphasis on the environment, we pay more and more attention to "low-carbon economy" and "ecological civilization", so the main theme of the world is in line with new energy. As we all know, new energy can better meet the current demand because of its small pollution, large reserves and wide distribution.
In many branches of new energy, fuel cells do not have absolute right to speak. In the scene where people most often use new energy-automobiles, electric vehicles equipped with lithium batteries have become the leaders of new energy, accounting for half of the new energy.
However, even in the most mainstream applications at present, electric vehicles have inevitable shortcomings, such as long charging time, short cruising range and high battery maintenance costs. Limited by the development of technology, there are still many uncertain factors whether electric vehicles can become the absolute only choice for people to travel. In addition to lithium batteries, there are many other technical problems waiting to break out.
Hydrogen fuel cell vehicle is a device that generates electric energy through the chemical reaction between hydrogen and oxygen, and it is a device that uses chemical energy to generate electricity, thus driving the vehicle.
It is actually an extended-range electric vehicle with compressed hydrogen as fuel. However, unlike today's more common fuel extended-range electric vehicles, its emissions are only pure water, which can truly achieve no greenhouse gas emissions. Compared with pure electric vehicles, it is also very convenient to replenish fuel, which is almost the same as that of fuel vehicles, and there is no inconvenience of long charging time of pure electric vehicles. This makes it a new technical direction pursued by many countries.
Automobile is one of the best carriers of fuel cell.
As early as? 20? A few years ago, a prototype powered by hydrogen fuel cells appeared. 1999? At the 2008 Tokyo Motor Show, Honda launched? FCX？ Concept car, by Ballard Power Systems (Ballard? Power? System) is to make hydrogen fuel cells? 78kW？ Power output of EPA? What is the certified cruising range? 170? Miles (about? 273? Kilometers).
Hydrogen fuel cell vehicles have a high demand for charging infrastructure. Hydrogen fuel cell vehicles can only be charged at hydrogen refueling stations. If the infrastructure is not distributed on a large scale, people's travel will become a problem. According to the White Paper on Hydrogen Energy and Fuel Cell Industry in China issued by China Hydrogen Energy Alliance, as of? 20 18? At the end of the year, a hydrogen refueling station was built in China. 23? Block, accounting for about the proportion of global hydrogen refueling stations? 6.23%。
But people have not given up this clean energy. As early as 2002, the Water-Hydrogen Alliance began to develop hydrogen energy, and began to develop small mobile hydrogen production machines. Guangdong Hehe was established on 20 13, devoted to the research and development and application of hydrogen energy conversion technology and water-based energy technology. The developed water-hydrogen power module AH7500 (water-hydrogen machine) has been successfully tested in electric vehicles. Water-hydrogen power module uses catalytic reforming and purification technology to obtain high-purity hydrogen from alcohol water, and generates electricity, heat and other energy sources through proton membrane system. The hydrogen used by the water-hydrogen vehicle equipped with this module is always available. As long as there is enough water-hydrogen raw material (methanol water) in the raw material box, the endurance of the water-hydrogen vehicle can be guaranteed. It can effectively alleviate the problem of insufficient coverage of charging infrastructure and reduce the investment in charging facilities.
After years of research and development, the technology of water-hydrogen generator has gradually matured, especially in the field of automobiles, which has received extensive attention from all walks of life and strong support from policies.
Hydrogen fuel cell vehicles are expected to become a direction of future development with their own clean advantages.
