1. In terms of energy refill time
Hydrogen car charging time is very short, less than 5 minutes. Even with current supercharging stations, charging a pure electric vehicle takes about half an hour.
2. Regarding driving range
Hydrogen fuel cell vehicles can achieve a range of 650-700 kilometers, with some models even reaching 1000 kilometers, a range that pure electric vehicles currently cannot match.
3. Production technology and costs
Hydrogen fuel cell vehicles only produce air and water during operation, eliminating the need for fuel cell recycling and making them very environmentally friendly. While electric vehicles (EVs) do not use fuel and have zero emissions, they primarily transfer pollution emissions, as coal-fired power plants constitute a very high proportion of China's electricity energy structure. Although centralized power generation is more efficient and pollution is easier to reduce, strictly speaking, unless the electricity for an EV comes from clean energy sources such as wind and solar power, EVs are not absolutely environmentally friendly. Furthermore, the recycling of spent EV batteries is a significant issue. Pure electric vehicles do not produce pollution, but they do have indirect pollution from coal-fired power generation. However, in terms of current production and technological costs, hydrogen fuel cell vehicles are technically and structurally very complex. Hydrogen fuel cell vehicles primarily rely on hydrogen and oxidation reactions to generate electricity to power their engines and require the precious metal platinum as a catalyst, which significantly increases costs, making pure electric vehicles relatively cheaper.
4. Energy efficiency
Hydrogen fuel cell vehicles are less efficient than electric vehicles. Industry experts calculate that once an electric vehicle starts, the power at the charging station will be lost by about 5%, battery charging and discharging will add another 10% loss, and finally the motor will lose 5%. The total loss is calculated to be 20%. Hydrogen fuel cell vehicles integrate the charging device inside the vehicle, and ultimately, their drive method is the same as pure electric vehicles, driven by an electric motor. According to relevant tests, if 100 kWh of electrical energy is used to generate hydrogen, then stored, transported, added to the vehicle, and then converted into electrical energy to drive the motor, the energy utilization rate is only 38%, and the overall efficiency is only 57%. Therefore, no matter how you calculate it, it is far less efficient than electric vehicles.
In conclusion, with the rapid development of new energy vehicles, both hydrogen fuel cell vehicles and electric vehicles have their advantages and disadvantages. Electric vehicles are the current trend. While hydrogen fuel cell vehicles may not replace electric vehicles in the future due to their many advantages, they will likely develop in tandem.
