What are the challenges of hydrogen fuel-powered battery vehicles?

First of all, if a car wants to go on the road, it's definitely not just a car's own business. It involves hydrogen production, storage, transportation, hydrogen refueling station, car hydrogenation, and the assembly of a fuel power battery system requires electrode plates, electrolytes, and exchange membranes. , Catalyst, diffusion layer and other components. Then the question is, how to produce hydrogen? The current mainstream hydrogen production methods include hydrogen production from coal, hydrogen production from chlor-alkali by-products, and hydrogen production from electrolysis of water. This drawback is still very clear. Zhitong Finance APP believes that, let alone hydrogen production from coal, the chemical energy in coal will be added a few more procedures. If the impure hydrogen contains carbon dioxide or carbon monoxide, it is easy to poison the battery's catalyst. Hydrogen production from chlor-alkali by-products relies on industrial product processing layout and is not suitable for large-scale promotion. Hydrogen production by electrolysis of water is also a long way from other energy sources, electrical energy, chemical energy, and electrical energy. However, if the initial energy is clean energy such as wind and solar energy, it is okay, if it is other forms of energy, the gain will not be worth the loss. In addition, hydrogen is a gas, and its volume density is extremely small, which brings great difficulties to storage and transportation. One is the low energy storage ratio, and the other is poor safety. In addition, the current layout of hydrogen refueling stations is very small, which is uncomfortable. From the battery itself, the high cost and sensitive physique make this person seem a bit cold. At present, the catalyst of hydrogen fuel power cell is mainly to use platinum. Although there are studies on other catalysts, platinum is still the best and has to be used. Moreover, the catalyst and the exchange membrane are a little squeamish, and it is easy to get sick or even go on strike if you get angry.
