A hydrogen fuel cell refers to a device in which hydrogen generates electricity through a chemical reaction with oxygen (a "hydrogen internal combustion engine" driven solely by combustion of hydrogen, which has also appeared, such as BMW's hydrogen energy 7 series). The driving force of a hydrogen fuel cell vehicle comes from a motor like a pure electric vehicle. Therefore, a hydrogen fuel cell vehicle can be understood as a "electric vehicle with a hydrogen fuel generator."
Hydrogen fuel cell vehicle principleIn the fuel cell stack, a reaction in which hydrogen and oxygen are combined is carried out, in which a charge transfer occurs to generate an electric current. At the same time, hydrogen reacts with the oxidative reaction to form water.
The fuel cell stack acts as a chemical reaction cell, and its most critical technology core is the “proton exchange membraneâ€. On both sides of the film, the catalyst layer is closely attached to decompose the hydrogen into a charged ion state. Because the hydrogen molecule is small in volume, the electron-carrying hydrogen can be released to the opposite side through the tiny pores of the film, but the electron-carrying hydrogen crosses. During this film hole, electrons are stripped from the molecule leaving only positively charged hydrogen protons through the film to the other end. Hydrogen protons are attracted to the electrodes on the other side of the film in combination with oxygen molecules.
The electrode plates on both sides of the membrane split hydrogen into hydrogen ions positively and electrons, oxygen into oxygen atoms to capture electrons into oxygen ions (negative electricity), electrons form current between the electrode plates, and 2 hydrogen ions and One oxygen ion combines into water, and water becomes the only "waste" in the reaction. In essence, the entire operation process is the power generation process. As the oxidation progresses, the electrons are constantly transferred to form the current required to drive the car.

Overview of hydrogen fuel cell vehicle researchforeign
According to the latest statistics, in the fuel cell vehicles launched so far, compressed hydrogen is the most concerned, mainly because the fuel supply of this model is the most technically simple and feasible. The FCV (fuel cell vehicle) produced by each company has made great progress in terms of driving range, maximum speed, fuel economy, and hydrogen storage pressure.
At present, developed countries such as Japan, South Korea and the United States have focused on the development of large-scale fuel cells, and the corporate world has also invested heavily in research and development of fuel cell technology. Now, many important achievements have been made to make fuel cells. It is about to replace traditional generators and internal combustion engines and is widely used in power generation and automobiles.

For domestic use, the research on hydrogen fuel internal combustion engines is lagging behind. It was not until the 1980s that the exploration of hydrogen internal combustion engines, which were mainly represented by famous universities such as Zhejiang University and Tianda, emerged, and the research work mainly focused on hybrid fuel engines. Hydrogen fuels are usually used as auxiliary fuels and gasoline. Mixed combustion of traditional fuels such as diesel;
In general, China's research on hydrogen engines started late. In many key technical fields related to the development of hydrogen fuel engines, it is still in a blank stage or just starting stage, such as large-scale production of hydrogen energy, engine supercharging technology, Hydrogen supply systems and system safety, engine control strategies, pollutant emission control technologies, integrated electronic control management systems, etc. are all inadequate. In terms of the content of the research, the vast majority is only the theoretical exploration and research of colleges and universities. The gap in core technology is still large, and the overall technical level is not high.
Realization of mass production of hydrogen fuel cell vehicle offerToyota Mirai sells for around 7 million yen overseas and enjoys 5 million yen after government subsidies, equivalent to about 265,000 yuan. Liquid hydrogen is used as a power source, and liquid hydrogen is stored in a high-pressure hydrogen storage tank located in the rear half of the vehicle body. The entire hydrogen tank can be filled from 0 in 3-5 minutes, and the cruising range can reach 700km.

Honda Clarity, which was launched at the Tokyo Motor Show in November 2017, is equipped with a hydrogen fuel cell power system with a lithium-ion battery pack placed under the floor of the car. The maximum power of the motor is 177 hp and the fuel cell power is 103 kW. The hydrogenation time is about 3 minutes, and the cruising range under the JC08 condition test can reach 750km. According to Honda executive vice president John Mendel at the Washington Motor Show, the new car will be available in California later this year, priced at about $60,000 (about RMB 395,000), and the rental fee will be less than $500 per month.

Hyundai ix35 FCV officially went offline at the Ulsan Plant in South Korea on February 26, 2013, becoming the world's first production hydrogen fuel cell vehicle. The price is as high as 150 million won, equivalent to 855,000 yuan. The Fuel Power System (BOP) is divided into three main areas: Thermal Management System (TMS), Air Treatment System (APS), and Fuel Processing System (FPS). It can fill up the hydrogen fuel in 10 minutes and can exercise up to 415km.

As one of the main energy sources for power supply in the future, hydrogen energy has many advantages. First, it is clean and hygienic. The product after hydrogen combustion is water, which will not pollute the environment. Secondly, hydrogen is higher than the calorific value of gasoline when burning. Hydrogen is Renewable energy, and can be extracted from many substances in the world.
