In the past ten years, due to environmental changes, the automobile toward fuel, pure electric, fuel cell three directions of development, and pure electric vehicles and hydrogen fuel vehicles currently only belong to the "minority" group. But that doesn't stop them from replacing the possibility of gasoline cars in the future, so which is better, pure electric cars or hydrogen fuel cell cars? Which one will be the mainstream of the future?
1. In terms of energy filling time
Hydrogen cars can be recharged in less than five minutes. Even with the current supercharging pile ev, it takes about half an hour to charge a pure EV;
2. Range
Hydrogen fuel vehicles can have a range of 650-700 kilometers, and some models can even reach 1,000 kilometers, which is impossible for pure electric vehicles at present.
3. Production technology and cost
Hydrogen fuel cell vehicles produce only air and water during operation, and there is no recycling problem of fuel cells, which is very environmentally friendly. Although electric vehicles use no fuel and have zero emissions, they only divert pollution emissions, because coal-fired power accounts for a very high proportion of China's electricity energy mix. Although centralized power generation is more efficient and pollution problems are easier to reduce, electric cars are not strictly green unless they are powered by clean energy sources such as wind and solar.
In addition, waste battery recycling of electric vehicle batteries is a big problem. Pure electric vehicles have no pollution, but there is indirect pollution, namely environmental pollution caused by thermal power generation. However, in terms of the current production and technical costs of hydrogen fuel vehicles and electric vehicles, the technology and structure of hydrogen fuel cell vehicles are very complex. Hydrogen fuel vehicles mainly rely on hydrogen and oxidation reaction to generate electricity to drive the engine, and need precious metal platinum as a catalyst, which greatly increases the cost, so the cost of pure electric vehicles is relatively low.
4. Energy efficiency
Hydrogen cars are less efficient than electric ones. Industry experts calculate that once an electric car starts, it will lose about 5% of the power supply at the car's charging position, 10% more when the battery is charged and discharged, and eventually 5% of the motor. Calculate the total loss at 20%. Hydrogen cars integrate a charging device inside the car and are ultimately driven by an electric motor in the same way as pure electric cars. According to relevant tests, if 100 kWh of electric energy is used to generate hydrogen, and then stored, transported, added to the vehicle, and then converted into electric energy to drive the motor, the utilization rate of electric energy is only 38%, and the utilization rate is only 57%. So no matter how you count it, it's far lower than an electric car.
To sum up, with the rapid development of new energy vehicles, hydrogen vehicles and electric vehicles have their own advantages and disadvantages. Electric cars are the current trend. Because hydrogen cars have many advantages, although they may not replace electric cars in the future, they will develop in tandem.
