A few days ago, the reporter learned from the media that Washington State University has made a major breakthrough in the field of solid oxide fuel cells (SOFC). It is reported that this breakthrough can greatly reduce the promotion cost of solid fuel cell technology, and can reduce pollution while achieving higher efficiency. It may be expected to replace gasoline engines in the future.
It is reported that this new technology was mainly developed by Ph.D. students Qusay Bkour and Su Ha, a professor of Gene and Linda Department of Chemical Engineering and Bioengineering. This is a unique and inexpensive nanoparticle catalyst that enables the fuel cell to use gasoline, etc. The conversion of liquid fuel into electrical energy without pauses in the electrochemical process ultimately contributes to the realization of efficient gasoline-powered vehicles with low carbon dioxide emissions, because carbon dioxide emissions are one of the causes of global warming.
Why promote fuel cells?
From a macro perspective, fuel cells have the same strategic position as pure electric batteries. One is to get rid of petroleum energy dependence and achieve renewable resources; the other is to be an emerging technology industry that can stimulate the development of the domestic economic environment; the third is to effectively control the road Emissions and improve the urban environment.
From a microscopic point of view, fuel cell vehicles have the same charging convenience as fuel vehicles, and it only takes 3 to 5 minutes to refuel with hydrogen; secondly, fuel cells have higher energy density and energy conversion efficiency is also very good , You can achieve the same endurance and power as fuel vehicles.
As early as in the "Thirteenth Five-Year National Science and Technology Innovation Plan", China mentioned the development of hydrogen fuel cell technology. The goal is that by 2030, the number of fuel cell vehicles will reach 2 million, the number of hydrogen refueling stations will reach 1,000, and the industrial output value will exceed 1 trillion yuan. At present, there is no set of guidelines for the development of hydrogen fuel cells in China. Compared with pure electric vehicles, the upstream and downstream industrial chains of hydrogen fuel cells basically need to be rebuilt, including hydrogen production, hydrogen transportation, hydrogen storage, hydrogen refueling stations and fuels. Construction of the entire industrial chain such as batteries. Toyota's boost was just an opportunity.
Why is it difficult to popularize fuel cells?
Although the fuel cell technology is good, it may be more difficult to promote than pure electric cars. Toyota, where hybrid technology is at its peak, can't bring fuel vehicles, is a good example. The first reason is that the cost is difficult to overcome, including the cost of hydrogen production, the cost of transporting hydrogen fuel, and the cost of storing hydrogen fuel. The cost of a hydrogen refueling station with a hydrogenation capacity of more than 200 kg is more than 10 million yuan, and it is too difficult to build the infrastructure. .
The second is the issue of technical strength. Looking at the world, that is, Toyota, Honda and Hyundai have made achievements in fuel cell vehicles.
The significance of new technology
The fuel cell converts chemical energy into electrical energy, so it is naturally more efficient than mechanical work. Due to the high cost of catalysts in the previous fuel cell technology, the promotion continues to be hindered. This new technology uses cheap nickel As a catalyst, it is possible to make fuel cell technology more widely commercialized.
