How Hydrogen Fuel Cell Works in Cars
On the operation of vehicle-mounted hydrogen fuel cells
Hydrogen fuel cells are becoming more and more popular in the application of vehicles. Its unique mechanism empowers the car, which is completely different from the usual fuel engines.
Hydrogen is the foundation of the fuel cell. When the vehicle is in the car, the hydrogen enters the anode, and there is a catalyst at the anode, which prompts the hydrogen molecules to split into protons and electrons. The protons can pass through the proton exchange membrane, and the electrons take a different path and travel along the external circuit due to the resistance of the membrane. This way, an electric current can be generated to power the car and make the car move.
At the cathode, oxygen also participates in this journey. The oxygen from the outside world enters the cathode, combines with the protons passing through the membrane and the electrons returning along the outer circuit to form water. This water is the residue of the reaction, clean and harmless to the ring.
In this way, the hydrogen fuel cell uses the reaction of hydrogen and oxygen, chemical energy as electrical energy, to power the car. It also has no smoke and dust discharge and no foul gas discharge, which is great for environmental protection. And compared with traditional fuel, its energy conversion rate is quite high, which can make the car last a long time.
However, there are also difficulties. Hydrogen production, storage and transportation are not easy. Production requires energy, and the quality of the method is related to cost and environmental protection; storage requires high pressure or low temperature techniques to retain hydrogen; transportation also requires special equipment due to the characteristics of hydrogen.
Despite the difficulties, hydrogen fuel cells are still promising on the road of vehicles. With the advance of science and technology, the technology is improving day by day. It must be a new way for cars to travel, leading the direction of future transportation, so that everyone on the road can enjoy clean and efficient car travel.
