LR721 battery.Why support the R&D and application of hydrogen fuel cells

　　The advantage of batteries is that they can make full use of existing power system facilities and directly utilize electricity from most renewable energy sources and nuclear power. Fuel cells need to solve the entire infrastructure construction and operation problems of hydrogen production, storage and transportation of hydrogen. It is still difficult to say that fuel cells will definitely become one of the indispensable new energy systems, or will definitely be better than battery systems. Now a group of people engaged in coal are promoting fuel cells and producing hydrogen from coal. "I take this opportunity to once again explain why I support the research and development and application of hydrogen fuel cells. Of course, benevolent people have different opinions and wise people have different opinions. 1. Rechargeable batteries and hydrogen fuel cells represented by ternary lithium batteries will have applications suitable for their own characteristics in the future. field, it will not be a relationship where there is me without others, there is others without me. However, because the application of ternary lithium batteries is relatively easy to obtain, so now the passenger car field is basically dominated by ternary lithium batteries, and the interests of this field Relevant parties deliberately emphasize the difficulties and shortcomings of hydrogen fuel cells. This is biased and is not conducive to the development of hydrogen fuel cells. 2. Just like hydrogen fuel cells have difficulties and shortcomings, lithium batteries also have many problems and shortcomings. . Spontaneous combustion accidents that have occurred many times have been deliberately downplayed. The recycling and processing of lithium batteries have not been completely solved, and the impact on the environment cannot be ignored. Lithium is not a popular chemical element. Although there are currently not many lithium battery electric vehicles, It is not large, and the proportion of production volume is not large, but it has caused the price of lithium to rise several times. If all electric vehicles use lithium batteries in the future, there will be problems with lithium resources and the price will also skyrocket. We cannot reduce the price of electric vehicles. Baodu relies on lithium batteries. 3. Lithium batteries have long charging time and limited range. Compared with hydrogen fuel cells, these two points are the weaknesses of lithium batteries. 4. Now a private car lithium battery weighs about seven , 800 kilograms. If used in a bus, such as the Silver Dragon Bus, the lithium battery weighs several tons. It not only consumes a large amount of precious metal lithium, but also cannot be used in large quantities. Because of this problem, it is even more impossible to use it. Lithium batteries will serve as the power source for trucks in the future. In the field of trucks and large buses, hydrogen fuel cells have obvious advantages. 5. Some people say that batteries can make full use of the current power system and can use renewable energy and nuclear power. Hydrogen fuel cells The required hydrogen can also be produced by using renewable energy and nuclear power. There have been many reports on this recently. Some coal companies, such as Shenhua, participate in the Hydrogen Energy Industry Alliance because their coal chemical industry has by-products. A lot of hydrogen. The same goes for Sinopec. So Sinopec is also very keen on developing hydrogen energy.
