Vehicles use the ECU to inject fuel, and the high-voltage coil generates high-voltage electricity to supply the spark plug. The mixture of gasoline and air is then ignited by the spark plug's electric spark, causing an explosion that generates power. This power is transmitted to the belt, which drives the wheels to rotate. The types and basic structure of vehicles are introduced as follows: Types of Vehicles: Cars are specifically categorized into micro cars, subcompact cars, compact cars, midsize cars, full-size cars, and luxury cars. Comfort and spaciousness vary with the level and price. Consumers can choose the appropriate vehicle based on their financial situation and needs. Basic Structure of Vehicles: Vehicles typically consist of four main parts: the engine, chassis, body, and electrical equipment.

The working principle of hydrogen fuel cell vehicles sounds pretty cool. There's a high-pressure hydrogen storage tank on the vehicle filled with liquid hydrogen. When driving, the hydrogen is sent to the fuel cell stack; there's a special membrane there where hydrogen splits into protons and electrons at the anode, with the electrons flowing into the circuit to generate electricity that drives the electric motor, while the protons pass through the membrane to the cathode. At the cathode, oxygen is drawn from the air and combines with the electrons and protons to form water vapor, which is then expelled. The entire process involves no combustion, resulting in zero tailpipe emissions—only water and heat are produced. Refueling with hydrogen is similar to gasoline refueling, taking just a few minutes, and offers long driving ranges. Technically, the efficiency can reach up to 60%, far more energy-efficient than gasoline vehicles, but the costs are high, requiring specialized tank designs to ensure safety. I believe future adoption will depend on the widespread availability of more hydrogen refueling stations.

As an environmentally conscious individual, I believe the core of hydrogen fuel cell vehicles lies in the fuel cell: hydrogen is fed from the tank into the cell, reacts with oxygen to generate electricity to power the car, and only produces water vapor as a byproduct without releasing any pollutants. This represents truly clean energy with zero carbon dioxide emissions or noise pollution. Compared to electric vehicles that rely on potentially coal-dependent charging infrastructure, hydrogen produced using wind or solar energy achieves genuine eco-friendliness. The hydrogen storage tanks are made of robust composite materials, ensuring safety and reliability. While driving, you only hear the quiet hum of the electric motor with smooth acceleration. Although hydrogen refueling infrastructure is currently limited and production costs need optimization, from a sustainability perspective, this technology eliminates air pollution and helps combat climate change. Vigorously promoting this technology would bring significant ecological benefits.

I guess the working principle of hydrogen fuel cell vehicles is quite simple: there's a tank in the car that stores hydrogen, which you refill at hydrogen stations. When driving, the hydrogen flows into the fuel cell device, combines with oxygen from the air, and undergoes a reaction like a tiny chemical plant, generating electricity that directly powers the electric wheels. The only byproduct is water vapor, clean and without any soot. Refueling with hydrogen is quick, unlike plug-in charging which takes forever. The reaction happens automatically, and the car glides silently. The whole process is super eco-friendly, causing no harm to the planet. It's interesting to learn about, involving just basic chemical changes, and is quite efficient. Although hydrogen stations are still few and the technology is developing, I find it easy to understand and practical.
