What's the technical route for an Fuel cell electric car

The purpose of developing electric vehicles is to save energy and reduce emissions. The automotive power must rely on independent intellectual property rights to produce electric vehicles with the lowest energy consumption and the lowest emissions. Some electric cars save only fuel, but not necessarily energy. TESLA was punished in Singapore for pursuing long-haul batteries, heavy cars, and power consumption. Therefore, it is necessary to develop high-power batteries.

So how do we do that? First, we must solve the four major anxiety problems of high-ratio power batteries. The first is mileage anxiety, the second is safety anxiety, the third is charging anxiety, and the fourth is price anxiety. It is difficult to market pure electric vehicles that rely on high subsidies to drive development. The longer the subsidy stops, the longer the mileage, the more difficult it is to sell vehicles with higher subsidies. Therefore, to use small and medium-sized pure electric vehicles as a breakthrough, the development of large and medium-sized vehicles can use pure electric-driven augmentation programs, and the price of small models of pure electric vehicles can be determined by the market.

I have mentioned in many reports that electric vehicles developed with lithium iron phosphate batteries do not need high-specific energy batteries, but only need to install scalers in pure electric vehicles. The first generation of augmented pure electric vehicles is simply to increase the mileage, that is, to make a generator on a simple pure electric vehicle. The battery optimization in a pure electric car will be relatively high. In the second generation, the engine was reduced and the battery was reduced. Not only did it save half of the money, but it also saved 50 % of the fuel. The third generation is the increase in power generation direct-drive electric vehicles, that is, the power generation in the car does not pass through the battery and directly drives the motor. It inherits all the advantages and further reduces the cost, and the fuel saving rate is also high. Because there is at least 10 % energy loss during the battery charging process, it also reduces energy loss relatively.

Some people will say that the increase program still needs to burn oil and is not the ultimate goal. But, our country changes from big country of automobile to big country of automobile, the people of the whole country will be happy. Energy conservation and emission reduction should be used as a horizontal standard to test the technological route of the augmentation program. The ultimate goal of electric vehicles is not necessarily a pure electric vehicle that does not burn oil. It is very likely that it will not burn oil and burn alcoholic electric vehicles. We need to put into production the third generation of incremental electric vehicles to cope with the impact of subsidy sloping on electric vehicles.

Although the fuel cell has a high specific energy, it is difficult to meet the requirements for changes in the function of the car. At this point, I would like to touch upon a few questions about fuel cells.

The first problem is the variety of fuel cells, because proton exchange membrane fuel cells are not the best. Here, we should pay attention to the following points: the energy efficiency of hydrogen; Safe transport storage is not very convenient; Fuel cells are short-lived and expensive; Key materials such as membrane technology still needs to be improved; Platinum resources are too small and catalysts need to be developed. Therefore, under solid oxide fuels, it is possible to burn only natural gas instead of hydrogen, but there is still controversy in the field of electric vehicles.

The second issue is the supply and cost of hydrogen. The process of hydrogen compression consumes energy and emits carbon dioxide. Therefore, the hydrogen energy conversion rate of Gaohe hydrogen energy is not correct. However, Qingxue University has proposed that 45 % of ethanol comes from the fermentation of sorghum stalks, which can be used not only for feed but also for winemaking. This approach has attracted the attention of the relevant authorities of the country and is now being vigorously promoted.

The third issue is the life of the PM fuel cell power system. Battery systems are complicated and difficult to maintain. Moreover, the air pollution is serious and the imported fuel will produce carbon monoxide. In addition, solid particles in the air can easily block the system, and purifying the air will increase costs and increase energy consumption, and the system will be more complicated. Therefore, the development of fuel cells needs to do a good job of basic research.

In short, the technical route of fuel cell electric vehicles is still being explored. Heavy subsidies and drastic promotion of PMFC industrialization will cause fraud and waste of resources.

I believe that the future of sustainable low-carbonized electric vehicles is powered by solar photovoltaic power and wind power to charge power cells and provide energy to the engine through biomass, thus forming an augmented electric vehicle. In other words, solar energy can provide energy. Now the country can use solar energy as a reserve, and there will be considerable ethanol production in the future.

The fourth issue is the development of lithium sulphur batteries. I think it can be done quickly, but it's hard to do well. Because it has five "low": low safety, low volume than energy, low discharge ratio, low energy conversion efficiency, and low number of cycles. If these problems can be solved, the power cell problem can be solved. Lithium-sulfur batteries can be used in places where the volume is loose and the weight is strictly limited, for example, drones can be used.

The fifth problem is lithium empty batteries. Its problem is likely to be "far not hydrolyzed far thirst." Because,lithium-empty battery energy conversion efficiency is too low, short life, lower than function. And last year, the American Agun Laboratory stopped researching and designing lithium-empty batteries. The foreigners 'approach is worth thinking about.
