First, fuel cells have unique advantages in using hydrogen as energy. There are two specific advantages. First, high efficiency, because we know that the efficiency of traditional cars is only 30% at most, due to the basic thermal definition of the cycle. Fuel cell hydrogen vehicles, such as the recent Toyota Future Car, can achieve 50%-60% efficiency under NEDC operating conditions and Japanese GC08 operating conditions, which is equivalent to twice that of traditional vehicles. Second, it is indeed zero-emission, because hydrogen uses the conversion process to combine with oxygen in the air and turn into water. In the future, if it is combined with renewable energy, such as wind energy and solar energy, water can be turned into hydrogen and oxygen. Hydrogen can be used as an energy source and turned back into water at the same time. There will be truly zero emissions during use. Regarding environmental issues, we all live in big cities and are deeply aware of air pollution. Carbon dioxide is involved in global warming. Before we save the world, we can save ourselves by improving the air in our big cities. The transportation sector accounts for 25% of all PM2.5. I recently read reports that the proportion in big cities like Shanghai will be even higher.

Second, hydrogen fuel cell vehicles have unique advantages in terms of driving range and charging time. Fuel cell vehicles can actually also be electric vehicles. Electric vehicles have made technological progress and their driving range is also increasing. The main things that electric vehicles need to overcome now are driving range and charging time. Hydrogen fuel cells have unique advantages in this regard. Fuel replenishment only takes three to five minutes, which is similar to refueling a car. The driving range can currently reach five to six hundred kilometers. The fuel storage device is the size of a traditional car fuel tank. As energy technology improves, there is no problem in gradually increasing the driving range.
Third, from the perspective of national energy strategy, if our country wants to turn a big automobile country into a powerful country, new energy is the only way to go. The energy structure is relatively simple and should be diversified. At present, our country relies on oil imports for more than 60%. With economic development and population increase, it will reach 70% in the future. Energy security is a big problem.
SAIC’s process of developing hydrogen fuel cell vehicles
As early as 2000, SAIC first came into contact with fuel cell vehicles. At that time, we worked with Pan Asia and General Motors to develop the Phoenix fuel cell vehicle. During the Beijing Olympics, SAIC developed the first generation of functional vehicles to prove that such vehicles can also run on the road. At the 2010 World Expo, SAIC developed more than 40 fuel cell vehicles on a larger scale. We already have full confidence in our technology in terms of vehicle safety, power performance and passenger operation. Since then, when SAIC formulated its new energy vehicle plan, it positioned hydrogen fuel cell vehicles as one of its three major development routes. Through the efforts of the past few years, SAIC has developed the third-generation fuel cell vehicle, and what will be on display will be the fourth-generation fuel cell vehicle. During the research and development process, SAIC's hydrogen fuel cell vehicles have made great improvements in various indicators, including driving range, reliability, durability and even environmental adaptability.
In order to verify the performance of the vehicles, we launched the "Innovation Journey New Energy Vehicles National Miles Tour" last year. SAIC's fuel cell vehicles passed through 15 provinces and autonomous regions and 64 cities, with a single vehicle mileage of 10,000 kilometers. In addition, the performance of SAIC's fuel cell vehicle has been verified in various extremely harsh environments such as the high altitude of Tibet and low temperatures in the north. In 2011, we participated in the "Bibendum" competition, an international energy-saving and environmentally friendly automobile competition, and won third place behind Toyota and Audi. In the 2014 Bib Gourmand Challenge, SAIC's pure electric vehicles, hybrid vehicles and fuel cell vehicles won first place in three groups respectively, achieving a grand slam.
For the fuel cell vehicles that will be unveiled at the auto show, SAIC uses dual power sources, taking advantage of the high power and high energy characteristics of fuel cells, relying on battery power to improve acceleration performance, and relying on fuel cells to increase driving range. This is our characteristic. In terms of driving range, SAIC’s fuel cell vehicles can last up to 400 kilometers with one refill of hydrogen. As the hydrogen storage capacity increases, the cruising range will further increase, and our future goal is to reach 500 kilometers. At the same time, the project has also derived other applications, such as fast power supply. If we have a fuel cell vehicle, then when a household encounters a power outage or a natural disaster, SAIC's fuel cell vehicle can provide its own emergency power supply.
SAIC fuel cell vehicle future development plan
The nationally planned fuel cell and future hydrogen energy commercialization process is proposed to be divided into four stages in the initial stage. In the first stage, when our car companies provide products, we can hope that they will be supplemented by hydrogen energy infrastructure during the launch process. In the second phase, there may be a crossover, and when initial commercialization occurs in the later stages, hydrogen infrastructure becomes a key factor. In the third stage, the technology is close to the requirements of industrialization, commercialization is expanding, and hydrogen infrastructure is developing faster than cars. In the fourth stage, when the technology meets the requirements of industrialization and industrialization accelerates, technology and hydrogen infrastructure may develop simultaneously. This is similar to the principle of "if you have chickens, you don't have to worry about eggs; if you have eggs, you don't have to worry about chickens."
When planning future applications, SAIC is also considering that its development will be based on the passenger car platform, because it has strict technical requirements. Then, when the power system is developed and matured, it can also be extended to other commercial vehicles, such as buses, logistics vehicles, etc. This is relatively easy to implement in terms of infrastructure, because a fleet on a given route only needs to establish a hydrogen refueling station.
