Who is the future development direction of hydrogen fuel cell and solid-state lithium battery?

Who is the future development direction of hydrogen fuel cell and solid-state lithium battery? As a clean, efficient, safe and sustainable new energy, hydrogen energy is regarded as the clean energy with the most development potential in the 21st century, and it is the strategic energy development direction of mankind. Hydrogen fuel cell vehicles have many characteristics such as pollution-free, low energy consumption, long endurance, and wide application areas. They have entered the stage of small-scale commercialization. The industry believes that in the next three to five years, that is, around 2020, the hydrogen energy industry will enter an explosive period. Compared with solid-state lithium batteries, the biggest advantage of fuel cells is their high energy density, which is 120 times that of lithium batteries. Solid-state lithium batteries started early, have a higher degree of commercialization, and lower vehicle costs, and can use the existing grid system for charging. Compared with fuel cells, the entire hydrogen refueling and hydrogen supply network must be built from scratch, and the cost is also Lower. Therefore, the core of the competition between the two is the competition of energy density vs. cost. Which is better, hydrogen fuel cell or lithium battery? At present, the development of lithium batteries has been on the right track. Whether in Europe, America, Korea, Japan, China, they have already begun industrialization; the development of fuel cells is still in its infancy, but there are still many pain points related to cost, safety, etc., which will take a long time To solve. Hydrogen fuel cells are currently being questioned, the main factors are: safety, high cost, its advantages are environmental protection and wide range of fuels. From an industrial point of view, the industrialization of solid-state lithium batteries has been completed, which can further stimulate other industries to form a network of development. In view of the scale of investment that countries around the world have paid in lithium batteries, it is difficult for hydrogen fuel cells to become the mainstream direction for at least the past ten years. The greater possibility is as a form of technical supplement to lithium batteries. At present, lithium batteries and fuel cells are the mainstream technologies that are expected to replace petroleum vehicles. Both have their own advantages and have huge room for improvement. If lithium batteries can increase their energy density and optimize cycle life, they will be more competitive; the core technology of hydrogen fuel cells, the huge cost of vehicle and hydrogen refueling station construction, and safety issues are still huge bottlenecks in industrial development. From the perspective of environmental protection and sustainable development, hydrogen fuel cells have more development prospects than lithium batteries, but from the perspective of short-term economic benefits, the development of lithium batteries is more market-competitive than hydrogen fuel cells. Solid-state lithium batteries are characterized by high safety and high energy density, while hydrogen fuel cell technology is basically mature and meets environmental protection requirements. With the decline in subsidies for electric vehicles and the same subsidies for fuel cell vehicles, which technology route represents the future of new energy vehicles, solid-state lithium batteries and hydrogen fuel cells?
