What is the difference between a fuel power battery and a lithium-ion secondary battery?

Hydrogen fuel power battery and lithium battery coexist. What is fuel power cell (FC)? How is it different from lithium ion secondary battery? A1: The working principle is the same as that of lithium ion secondary battery. When the negative electrode material is oxidized by the positive electrode material, the charge is released. Specifically, a fuel power cell is a reaction of hydrogen gas to water, which is the same as slow combustion. The difference is that H ions replace lithium ions for mobile discharge (generation), so the fuel power battery can also be said to be an H (hydrogen) ion battery. However, all non-rechargeable primary batteries are currently available on the market. Composition of PEFC (Solid Polymer Fuel Power Cell) Q2: Compared with lithium ion secondary battery, which characteristics? If it can not be charged, is it disposable? A2: The combustion energy density of hydrogen itself is three times that of gasoline . Even in a fuel power battery system, the energy density is 5 times that of a lithium ion secondary battery, so it can be used for a long time. Even if the initial output is exhausted, it will not be a one-off. The reason is that the anode material (oxygen) exists in the air and does not disappear. The negative electrode material (hydrogen) is also a gas, which can be refilled after use. Where does hydrogen come from? (For example) it can be extracted from water or the sun, and when the extracted hydrogen is used in fuel power cells, it returns to the water. Solar power and hydropower equipment, fuel power cells can be said to be a mechanism that converts solar energy into electricity through water and hydrogen. The material cycle diagram including hydrogen production Q4: For 20 years, Japan has been talking about fuel power cells and hydrogen society. Has it really come this time? Recently, the development of various technologies and changes in the social environment indicate that the times have come. For example, the output density is more than three times what it was 20 years ago. Electric vehicles (evs) and drones (uavs) and other fields have caused a lot of controversy, but in practice, their pain points (such as cruising range and charging time) have deepened, and people are increasingly aware that fuel-powered batteries may be able to Deal with these issues. City gas and methanol are currently widely used fuels, but part of the energy is also consumed in the hydrogen conversion process. By directly using pure hydrogen, the original function of the fuel power cell can be obtained. The infrastructure is now improving. If fuel power batteries come out, do you still need lithium-ion secondary batteries? How does FCV communicate with EVs? Answer 5: The best way to use them is technically different. By combining fuel-powered batteries with lithium batteries, you can create new uses that have not yet been completed, or prevent waste of money. Many existing fuel cell vehicles (FCV) are equipped with large-capacity secondary batteries, which are actually in the shape of semi-electric vehicles. Therefore, economic rationality is the most important promotion, and the foreseeable trend is to use lithium-ion secondary batteries. FCV considers the first introduction of commercial vehicles (buses, long-distance trucks, forklifts, drones, etc.), where endurance and output are very important. Assuming the popularity of autonomous driving in the future, FCV is also likely to be adopted by city cars.
