What are the advantages of fuel power batteries compared with general chemical batteries?

Fuel power cell is a kind of power generation equipment that directly converts chemical energy and oxidant in fuel into electrical energy. Fuel and air are separated into fuel power cells and electricity is generated. It has positive and negative electrodes and electrolytes, and looks like a battery, but in essence it cannot store electricity, but is a power plant. Compared with traditional chemical batteries, fuel power batteries can supplement fuel, usually hydrogen. Some fuel power cells can use methane and gasoline as fuel, but they are usually limited to industrial uses such as power plants and forklifts. The basic principle of a hydrogen fuel power cell is the reverse reaction of electrolyzed water, which separates hydrogen and oxygen and supplies it to the anode and cathode. When hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons through the external load to reach the cathode. The working principle of hydrogen fuel power battery is: hydrogen fuel power battery anode (cathode), through the use of catalyst (platinum), electrons are separated in a hydrogen atom, and the hydrogen ions (protons) that have lost electrons pass through the proton exchange membrane to reach the fuel. In the cathode plate (anode) of the power battery, the electrons do not pass through the proton exchange membrane. The electrons only pass through the external circuit to reach the cathode plate of the fuel power battery and then attack the current of the external circuit. When the electrons reach the cathode plate, they recombine with oxygen and hydrogen ions to form water. Since the oxygen supplied to the cathode plate can be obtained from the air, the continuous supply of hydrogen to the anode plate, air to the cathode plate, and the timely removal of steam can provide continuous power supply. The electricity generated by the fuel power battery can be sent to the electric motor through inverters, controllers and other equipment, and then driven by wheels such as the transmission system and drive axle to drive the vehicle on the road. Compared with traditional vehicles, the energy conversion efficiency of fuel cell vehicles is 60% to 80%, which is 2 to 3 times that of internal combustion engines. Fuel power cells use hydrogen and oxygen as fuel. The product is pure water. Therefore, the true meaning of the hydrogen fuel cell vehicle is a zero-emission, zero-polluting vehicle, and hydrogen fuel is the perfect vehicle power!
