The working principle of fuel cell vehicles

The working principle of fuel-powered battery vehicles FCV is a kind of vehicle driven by electricity from the on-board fuel-powered battery equipment, which can reduce dependence on foreign oil and reduce harmful emissions. Fuel-powered battery vehicles use hydrogen fuel instead of gasoline, and they do not emit harmful gases. The potential of this skill is huge, but there are still some skills to overcome. 1. The power control unit processes the current. 2. Compared with internal combustion engines, electric vehicles are quieter, smoother, more efficient, and require less maintenance. Battery pack-Allows hydrogen and oxygen to react with current to appear. 4. The high-output battery recovers the energy from braking and supplies supplementary energy to the motor. 5. The hydrogen storage tank stores hydrogen under extremely high pressure. Benefits to reduce greenhouse gas emissions The greenhouse gas emitted by gasoline and diesel vehicles is mainly carbon dioxide, which will cause global climate change. On the other hand, fuel-powered battery vehicles use pure hydrogen, which only emits water and heat, and does not emit greenhouse gases. Although the hydrogen processed by the plant also emits greenhouse gases, its emissions are far lower than that of traditional cars. Reducing dependence on oil Hydrogen requires only renewable resources such as water, methane and agricultural waste. The use of hydrogen can reduce the dependence on oil, coal and natural gas at home and abroad. This will enable the country to reduce its dependence on oil and reduce its vulnerability to fluctuations in oil prices. Reducing air pollution Road vehicles have a huge impact on air pollution, while fuel-powered battery vehicles do not produce smoke and harmful particles. If hydrogen is extracted from fossil fuels, there may be some pollution, but it is far less than traditional car exhaust. There are not many models available for combat, and hydrogen refueling stations are not common. They are important to promote in California. The promotion of fuel-powered battery vehicles still has a long way to go. Vehicle capital. Fuel cell vehicles are currently more expensive than traditional vehicles and hybrid vehicles, but the price is falling. The US Department of Energy (Department of Energy) aims to reach US$30 per kilowatt by 2017. Manufacturers should continue to cut costs, especially fuel power cells and hydrogen storage, to better compete with traditional cars. The infrastructure for hydrogen processing, transportation, and fuel replenishment stations at gas stations is too weak to support the large-scale use of fuel-powered battery vehicles. The U.S. Department of Energy and other federal agencies are working with academic societies and automakers to develop solutions to deploy hydrogen infrastructure. It is estimated that by the end of 2015, more than 50 hydrogen refueling stations will be put into use in California. Durability and reliability of fuel power cells Today's fuel power cell systems are not as durable as internal combustion engines, especially under extreme temperatures and humidity. The durability of fuel power cells is now only half of the commercial goal. In the past few years, the durability of fuel cell vehicles has been significantly improved, from 32,000 kilometers to 120,000 kilometers, but experts believe that to compete with traditional cars, 240,000 kilometers is necessary. Public education is necessary to let the public know the advantages of fuel power batteries. As with any new car, consumers always care about safety and reliability. Public education can speed up this process. Fuel cell vehicles usually use polymer electrolyte membrane (PEM) fuel power cells, also known as proton exchange membrane cells, to generate electricity from hydrogen and oxygen in the air. The figure below shows how the battery works. Fuel Power Cells Most fuel power cells can only produce 1.16 volts of electricity, which is far less than the energy required by cars. Therefore, it is necessary to pack many batteries into a battery warehouse. The potential energy of the fuel cell depends on the performance of the battery and the number of batteries.
