Since the 21st century, with the development of science and technology and the gradual improvement of human living standards, the demand for automobiles has also begun to grow rapidly. Automobile exhaust has become one of the main pollution sources of the atmosphere, and traditional internal combustion engine vehicles are difficult to solve the problem of fuel shortage and reducing pollutant emissions.
Therefore, in order to achieve the goal of energy saving and emission reduction, countries advocate the use of unconventional vehicle fuels as power sources for pure electric vehicles, hybrid vehicles, fuel cell vehicles and other new energy vehicles to reduce or even not emit greenhouse gases to reduce the impact on the atmosphere. Pollution. With the increasing awareness of environmental protection in countries around the world, a consensus has been reached to reduce or reduce greenhouse gas emissions, and many countries and regions have issued relevant policies to control and limit air pollution.
At present, in order to encourage the development and commercialization of fuel cell vehicles, governments around the world have introduced corresponding measures and support policies, and they are also full of expectations for the promotion and use of fuel cell vehicles. In my country, the "Energy-saving and New Energy Vehicle Industry Development Plan (2012-2020)" issued by the State Council in June 2012 included fuel cell vehicles, and planned the development direction of fuel cell vehicles, focusing on key basic components and FC systems. , Infrastructure and demonstration and other aspects to increase investment, and strive to keep pace with the world.
In May 2015, the "Made in China 2025" issued by the State Council proposed that it will continue to support the development of fuel cell vehicles, and that fuel cell vehicles of independent brands should be in line with the international advanced level and realize the localization of key materials and components. By 2020, my country’s FC life expectancy will reach the international level of 5000h, power density 2.5kW/L, cruising range 500km, durability 150,000km, hydrogenation time 3min, normal start at -30℃, 1000 fuel cell vehicles will be produced and run for demonstration . By 2025, my country will realize the regional small-scale operation of fuel cell vehicles.

In Europe, the European Union plans to achieve commercial operation of vehicle FCs by 2020, and implement fuel cell vehicles in four stages: comprehensive demonstration operation, expansion of fuel supply networks, access to major European automobile markets, and large-scale commercial operation. commercialize. Major EU countries have also successively laid out the fuel cell vehicle market. For example, the United Kingdom plans to reach 1.6 million fuel cell vehicles by 2030, and achieve a market share of 30% to 50% of fuel cell vehicles by 2050.
Fuel cell vehicles are a type of modern electric vehicles. Their body, power transmission system, and control system are basically the same as those of pure electric vehicles. The main difference lies in the difference in power batteries. Pure electric vehicles use secondary batteries such as lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries as power sources, while fuel cell vehicles use fuel cells as power sources, and all power loads are borne by fuel cells. The research and development of fuel cell vehicles began in the 1960s. In 1966, General Motors produced the world's first hydrogen fuel cell vehicle, which can accommodate two passengers, has a range of 193 kilometers, a speed of 113 km/h, and a battery life of 1,000 hours. , Limited to cost, safety factors and hydrogen refueling facilities and other reasons have not been able to continue development.
However, the United States has always attached great importance to the research and development of hydrogen energy and fuel cell vehicles. The electric vehicle project launched in 1987 included the research and development of fuel cell technology, and in 1992 it proposed the application of fuel cell systems to transportation. In 2003, the United States invested up to US$1.2 billion in research funding to promote hydrogen energy and fuel cell technology, which greatly reduced the production cost of fuel cells for vehicles. In terms of vehicle research and development, General Motors began to study the application of proton exchange membrane fuel cells in automobiles in 1990. In October 2001, General Motors launched the "Hydrogen Power III" liquid hydrogen fuel cell vehicle with a cruising range of 400km, a maximum power of 60kW, a crew of 5, a maximum speed of 130km/h, and an acceleration time of 13s from 0 to 100km.
