Cheap nanoparticle catalyst developed by American universities can improve the conversion efficiency of button battery 2032

Recently, reporters 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, while achieving higher efficiency and reducing pollution, and may replace gasoline engines in the future.

It is reported that this new technology is mainly developed by doctoral student Qusay Bkour and Gene and Linda Su Ha, professor of chemical engineering and bioengineering. This is a unique and inexpensive nanoparticle catalyst that enables the fuel cell to convert liquid fuels such as gasoline into electrical energy without pausing in the electrochemical process, which will ultimately help to achieve 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. First, they get rid of dependence on petroleum energy and realize resource renewable; second, as an emerging technology industry, they can stimulate the development of the domestic economic environment; third, they effectively control road emissions and improve the urban environment.

From a microscopic perspective, fuel cell vehicles have the same charging convenience as fuel vehicles, and it only takes 3-5 minutes to refill hydrogen fuel; secondly, fuel cells have higher energy density and good energy conversion efficiency, which can achieve the same endurance and power as fuel vehicles.

As early as in the "13th Five-Year Plan for National Science and Technology Innovation", my country mentioned the development of hydrogen fuel cell technology. The goal is to reach 2 million fuel cell vehicles and 1,000 hydrogen refueling stations by 2030, and the industrial output value will exceed 1 trillion yuan. At present, there is no set of guiding specifications 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 the construction of the entire industrial chain such as hydrogen production, hydrogen transportation, hydrogen storage, hydrogen refueling stations and fuel cells. Toyota's promotion is just an opportunity.

Why is it difficult to popularize fuel cells?

Although fuel cell technology is good, it may be more difficult to promote than pure electric vehicles. Toyota, which has reached the pinnacle of hybrid technology, cannot drive fuel vehicles, which is a good example. The reason is that the cost is difficult to overcome, including the cost of hydrogen production, hydrogen fuel transportation, hydrogen fuel storage, etc. A hydrogen refueling station with a hydrogen refueling capacity of more than 200 kilograms costs more than 10 million yuan, and the infrastructure is too difficult.

The second is the problem of technical strength. Looking around the world, only Toyota, Honda, and Hyundai have made achievements in fuel cell vehicles.

The significance of new technology

Since fuel cells convert chemical energy into electrical energy, they are naturally more efficient than mechanical work. Due to the high cost of catalysts in previous fuel cell technology, the promotion has been continuously hindered. This new technology uses cheap catalysts made of nickel, which may make fuel cell technology more commercially popular. Photovoltaic headlines
