This is a problem all over the world. Garbage, cars, air conditioning, etc. are causes of environmental pollution. Air pollution, which is a serious problem, is the main environmental pollution. In particular, cars produce a lot of exhaust gas, so this is the main problem considering air pollution and smog phenomenon. Another major problem with using the car is that it will lead to fuel shortage in the future. Therefore, we need more fuel switching for future cars to solve this problem. Many countries are developing and increasing their products every year to reduce CO2 emissions. For example, the development of hybrid, electric and hydrogen fuel cell cars is gradually improving air pollution and reducing fuel consumption. These are different methods of moving between fuel and future cars. Today, these cars, which are a new method, are taking center stage all over the world. The development of an environmentally friendly car is a guarantee for the future, which is why many car manufacturers are focusing on these. Hybrid, electric and hydrogen fuel cell cars have performance properties and their advantages and disadvantages, current development situation and problems. Today, hybrid cars are popular. The hybrid car works on a combination of electricity and fuels. The engine is powered by oil and that of the engine is powered by an electrical load. The motor is used to move the car, only when the electric motors are extremely slow and at measured speed. For example, when the car needs extra power, such as going up a steep hill or going uphill, a gasoline engine can be used to add extra boost to the engine. To go to middle of paper ......icle. Most hydrogen cars carry pure hydrogen at high pressure and the electricity is produced by the fuel cell that powers the electric motor that drives the vehicle. Each fuel cell is made up of two conductors. The oxygen passes and generates electricity and water. There are some positive effects. First, it eliminates greenhouse gases. Hydrogen cars come from the electrolysis of water. Second, hydrogen cars can run much longer than with batteries. Third, it eliminates pollution, these cars only produce water. Fourth, maintenance is very simple since there are few moving parts in the system. This poses some problems for popular cars. First, it is difficult to store, produce and transport hydrogen. Second, fuel cell cars have longer refueling and starting times. Third, the range is shorter than in a normal car..
