Hydrogen Fuel Cell Cars Working Principle
The working principle of hydrogen fuel cell vehicles
There are hydrogen fuel cell vehicles today. They are very efficient and clean. How strange the world is. The reason for this is because of their unique working principle.
The hydrogen fuel cell is actually an energy conversion device. It uses hydrogen as fuel and oxygen as oxidant. By electrochemical reaction, chemical energy is converted into electrical energy to drive the car forward. In this process, there is no soot, no turbidity, and only water is generated. It can be said that it is really clean.
In its device, there are two poles, one is the anode and the other is the cathode, separated by an electrolyte. When hydrogen enters the anode, under the action of a catalyst, hydrogen atoms lose electrons and form hydrogen ions (protons). Electrons flow along the external circuit to form an electric current for various parts of the car, such as driving the motor to rotate, which in turn drives the wheels and makes the car move forward; while hydrogen ions pass through the electrolyte and move to the cathode.
At the cathode, oxygen gets electrons and combines with the hydrogen ions that move over to form water. This series of reactions, over and over again, provides power to the car.
The beauty of hydrogen fuel cell vehicles is not only environmental protection, but also its efficiency. Compared with traditional fuel vehicles, the energy conversion rate is quite high, which can convert more fuel energy into mechanical energy. And its start is fast, the operation is quiet, and the driving feeling is very good.
However, its promotion has also encountered many problems, such as the production, storage and transportation of hydrogen, which is expensive and the infrastructure building is not complete. However, with time and advanced technology, the problem will be solved. Hydrogen fuel cell vehicles may become the mainstream of future travel and lead the transformation of transportation.
