What are the advantages and disadvantages of fuel power batteries?

1. When the boundary is the human society on the earth, regarding the significance of future energy structure adjustment, fuel power battery>lithium battery: How to improve the energy from fossil energy within one to two hundred years when fossil energy accounts for most of the primary energy share The key to the efficiency of useful work in consumer terminals and how to shield specific useful work forms from the determination of the primary energy structure is the transformation of energy conversion devices (which are easily analogous to the meaning of the steam engine of the industrial revolution), and the use of energy storage devices It is often to optimize the efficiency of energy utilization. 2. When the boundary is the vehicle, especially the vehicle on the ground, fuel-powered battery drive is more likely than lithium battery drive to become a car format similar to today: energy recovery within 3 minutes, and a driving range of more than 400 kilometers. The chemical reaction requires oxidizer, reducing agent (commonly known as fuel) and reaction site. Fuel-powered battery vehicles only need to carry two types: fuel and reaction site fuel power battery; while lithium battery vehicles need to carry all three, and the oxidizer and reductant in lithium battery The storage distance is very close (currently it is a membrane with a thickness of 100 microns). Even if it is not working, there is self-discharge. In order to achieve the life cycle of lithium batteries, they are often shallowly charged and discharged. The fuel is full, so the theoretical driving range in real use will be halved. This is that the effective driving range of current fuel-powered battery vehicles can reach more than 600 kilometers, while the effective driving range of lithium battery vehicles is generally less than 100. Fuel-powered battery vehicles are similar to natural gas internal combustion engine vehicles. The reaction site and fuel can be physically separated. Fuel filling is actually a physical process, as long as it is economically worthwhile. The energy recovery of lithium battery vehicles is a charging process, that is, electrolysis. The reaction must be controlled, otherwise side reactions will occur, and the fuel refueling speed is restricted by the degree of technological progress. Less than 1. When the boundary is a portable electronic device, due to the separation of oxidizer, reductant, and reaction sites, the system integration and simplification of the fuel power battery is far more difficult than that of fully integrated lithium batteries or other types of secondary batteries; 2. When the boundary When the grid is continuously backed up, the 2ns electronic equipment requires that it is almost impossible for the fuel power cell to send the separated oxidizer and reductant to the battery; the degree of industrialization: there is no product manufacturing for the fuel power cell; and Lithium batteries have formed a mass manufacturing industry for on-site power supplies of portable electronic devices. However, for automobiles, neither has formed a product manufacturing industry. The common technical difficulty lies in how the electrochemical reaction adapts to the large dynamic demand of the inductive load of the motor. It is easy to be confused by the statement: Lithium battery vehicles, because there is already a lithium battery industry, will be easier to replace the historical position of internal combustion engine vehicles than fuel-powered battery vehicles. Reasonable fallacy: Product development is based on customer needs. I have never heard that the internal combustion engine used in lawn mowers can be upgraded and transformed into automobile internal combustion engines. Relevant experience: battery cars, starting in 1900, lithium batteries This is the fourth wave, and it seems that it will not succeed in this 10 years. This is a difficult thing. The most fascinating statement: fuel-powered battery engine + lithium battery to form an electric-electric hybrid drive car, which can 1) increase the efficiency by 2 times; 2) zero emission of vehicles; 3) life and cost are easy to achieve; 4) get rid of the car’s oil Single dependency on resources.
