What is a Hydrogen-Powered Vehicle?
3 Answers
Hydrogen-powered vehicles are automobiles that use hydrogen as their energy source, converting the chemical energy produced by hydrogen reactions into mechanical energy to propel the vehicle. Below is an introduction to hydrogen-powered vehicles: Types of Hydrogen-Powered Vehicles: Hydrogen-powered vehicles are divided into two types. One is hydrogen internal combustion engine vehicles, which burn hydrogen (typically obtained through methane decomposition or water electrolysis) in an internal combustion engine to generate power for propulsion. The other is hydrogen fuel cell vehicles, where hydrogen or hydrogen-containing substances react with oxygen from the air in a fuel cell to produce electricity that drives an electric motor, which in turn propels the vehicle. Advantages of Hydrogen-Powered Vehicles: The greatest benefit of using hydrogen as an energy source is that its reaction with oxygen in the air produces only water vapor as exhaust, effectively reducing the air pollution issues caused by traditional gasoline-powered vehicles.
Hydrogen fuel cell vehicles are quite fascinating. Unlike regular electric cars that rely on batteries, they use hydrogen as fuel! I've studied the principles behind these vehicles: there's a fuel cell system inside the car that mixes hydrogen and oxygen to trigger a chemical reaction, directly generating electricity to power the motor. The most amazing part is that the only emission is water vapor, with zero tailpipe pollution. These cars drive as quietly as electric vehicles, but refueling with hydrogen is much faster than charging—just 3-5 minutes for a range of 500-600 kilometers. However, the biggest issue right now is the scarcity of hydrogen refueling stations, with only a few dozen in the country, and hydrogen production costs are more than double that of charging. If hydrogen technology becomes as widespread as charging infrastructure one day, it might just give electric vehicles a run for their money.
As an environmental advocate, I have a special fondness for hydrogen fuel cell vehicles. Their biggest advantage is absolutely zero pollution! Whether it's driving or the hydrogen production process, as long as solar or wind power is used to electrolyze water, the entire cycle is completely green. I test-drove Toyota's Mirai, and what came out of the exhaust pipe was literally pure water - far more eco-friendly than gasoline-powered cars. Although hydrogen refueling stations are currently much scarcer than gas stations, major cities like Beijing and Shanghai have already built quite a few. The main drawback is the cost - refueling expenses are about 0.5 RMB per kilometer, 30-40% more expensive than pure electric vehicles. However, with future breakthroughs in liquid hydrogen transportation technology, I estimate hydrogen vehicles will become the backbone of urban public transportation within ten years.
