Researchers have invented cost-effective new fuel power cell technology

Researchers at the University of Delaware have determined that ammonia is a source of engineered fuel power cells, which can supply cheap and powerful fuels for cars, trucks and buses, and reduce carbon emissions. Fuel power battery is a pollution-free energy source, which can convert chemical energy into high-efficiency, zero-emission electrical energy. Data map Researchers at the University of Delaware are studying technologies that make fuel-powered batteries cheaper and more powerful, so that fuel-powered cell vehicles can become a viable option for everyone in the future. Traditional fuel power cell research involves hydrogen fuel power cells, but researchers at the University of Delaware are designing fuel power cells that use ammonia. Researchers have found that among the fuels processed by renewable energy, ammonia has the lowest cost. Brian Setzler, a postdoctoral researcher at the University of Delaware, an important author of the study, said: As a nitrogen-based liquid fuel, ammonia is cheaper to store and distribute than hydrogen and prevents other liquid fuels. Carbon dioxide emissions, and the processing cost of these liquid fuels is very high. However, the challenge of this research is that ammonia is not useful in proton exchange membrane fuel power cells. Ammonia is more difficult to oxidize than hydrogen, which makes ammonia fuel power cells generate less power than hydrogen fuel cells. The team solved the first problem by using a hydrogen-oxygen proton exchange membrane fuel power cell, which has been studied in the laboratory of Yushan Yan, a distinguished engineering professor at the University of Delaware, for more than ten years. With a US$2.5 million grant from the U.S. Department of Energy’s ARPA-E fuel replenishment project, a research team at the University of Delaware designed a fuel-power cell exchange membrane that can operate at higher temperatures to accelerate ammonia oxidation. The researchers pointed out that through these improvements, they have demonstrated a prototype of a new type of ammonia fuel power cell with a peak power density of 135 milliwatts per square centimeter, which makes up most of the performance gap compared with hydrogen.
