5 minutes of hydrogen charging, 2000KM range!Volkswagen: Electric is just a transition, hydrogen is the future

When it comes to hydrogen fuel vehicles, the first thing that comes to mind for many people is Toyota's MIRAI, Toyota is indeed the earliest car company with the largest number of patents in hydrogen fuel vehicles, but it is not only Toyota that lays out hydrogen fuel vehicles, almost all mainstream car giants in the world are developing hydrogen fuel vehicles, including the Volkswagen Group.

Compared with the Toyota MIRAI with a range of 850 kilometers, Volkswagen is developing a hydrogen fuel vehicle with a range of up to 2,000 kilometers, and recently Volkswagen published a patent application in Germany, saying that it is currently working with the German company Kraftwerk Tubes to develop a new type of hydrogen fuel cell, which can be used in a production model of Volkswagen in the future, and this new battery can make the car range up to 2,000km.

What is the concept of 2000 kilometers? At present, the fuel tank of fuel family cars is about 50 liters, the urban range is about 600-700 kilometers, and the high-speed range is about 800 kilometers, which is already a relatively fuel-efficient model. The range of electric vehicles has just exceeded 1,000 kilometers, but the actual range is discounted, and the winter and high-speed range are directly cut in half.

Compared with electric vehicles, hydrogen fuel vehicles can be charged faster, hydrogen can be replenished in 5 minutes, and the range is more stable, less affected by vehicle speed and temperature, and will not become an electric father in seconds in winter. Compared with gasoline vehicles, hydrogen fuel vehicles are more environmentally friendly, emitting only water, and are less expensive to drive.

As we all know, Japan is limited to its own national conditions, and the whole country is betting on hydrogen energy, and now Volkswagen's hydrogen fuel vehicles have a range of 2,000 kilometers at once.

Many people don't believe this information very much, Toyota has been studying for so many years, Volkswagen wants to overtake the car? Is it so easy? In fact, the most critical point is that Volkswagen has made new breakthroughs in key technologies.

Hydrogen fuel power battery, simply put, converts the chemical energy of hydrogen into electrical energy, and then uses a small battery as a transfer station to drive the vehicle forward, which is very similar to a hybrid car, except that the electric energy generated by the engine of the hybrid car is changed to the fuel cell to provide electricity.

The positive and negative electrodes of the fuel cell have a layer of separators, and under the action of the catalyst, the electrons in the outer shell of the hydrogen atom will be free out and become independent electrons + hydrogen ions. The hydrogen fuel cell patent filed by Volkswagen and Kraftwerk Tubes is an improvement on this separator. Unlike the plastic membranes of Hyundai and Toyota's fuel cells, they use ceramic membranes. This ceramic membrane can improve the efficiency of fuel cell power conversion, which is the key to a range of more than 2,000 kilometers.

This kind of ceramic membrane can achieve platinum-free mass production, which is very important, Toyota MIRAI's hydrogen fuel car is sold for nearly 800,000, and Changan's hydrogen fuel car is sold for nearly 700,000, in addition to the small scale of mass production can not dilute the cost, there is also a reason that platinum is needed as a catalyst, and this ceramic membrane does not need platinum as a catalyst, because the cost of this hydrogen fuel cell is much lower.

Sascha Kühn, CEO of Kraftwerk Tubes, said: "Regardless of the manufacturer, our goal is to introduce our technology in series production cars by 2026. "In other words, in about four years, hydrogen fuel vehicles with a range of more than 2,000 kilometers may meet us.

In fact, although we hear more about Toyota's voice in the field of hydrogen fuel vehicles, but in fact, Volkswagen is not late to contact hydrogen fuel vehicles, as early as 2014, Volkswagen launched the Golf Variant HyMotion, and was officially released at the Shanghai Auto Show in 2015, hydrogen refueling for 3 minutes, can range 500 kilometers, but because Volkswagen believes internally, electric vehicles may be the next outlet, so later did not launch a production car.

In addition to the Golf Variant HyMotion, Volkswagen also released the Audi A7 h-tron in 2015, which accelerates from zero to 100 in just 7.9 seconds, and the car's hydrogen tank can store about 5 kilograms of hydrogen at a pressure of 700 bar, enough to drive the vehicle for more than 500 kilometers.

The reason for Volkswagen's renewed focus on hydrogen vehicles is related to Volkswagen's new CEO, Herbert Diess, who does not support the development of hydrogen vehicles, while the current CEO Omubo is a major supporter of hydrogen vehicles.

The advantages and disadvantages of hydrogen fuel vehicles are obvious, the biggest disadvantage is that the price is expensive, the supporting infrastructure is not perfect, but the prospect is broad, the charging time is short, the battery life is stable, environmental protection and pollution-free, and hydrogen can be extracted from water electrolysis and industrial by-product hydrogen, which is of great significance for countries lacking oil resources.

At present, national ministries and commissions, provinces and cities have intensively introduced policies to encourage the development of hydrogen energy, hydrogen energy may not be now, but in the future, hydrogen energy will occupy an important position in our energy system, when the endurance of 2000 kilometers, 5 minutes of "full blood resurrection" hydrogen fuel vehicles released, electric vehicles may really feel the pressure.
