A new family of chemical compounds that has the potential to revolutionize fuel cell technology and help in reducing global carbon emissions has been discovered by researchers.
FREMONT, CA: The research team the University of Aberdeen has described the breakthrough as equivalent to discovering “a needle in a haystack,” and also, the chemical compounds are collectively known as hexagonal perovskites might be the key to unlocking the potential of ceramic fuel cells. Researchers from everywhere have been looking for compounds that may overcome these issues in a relatively unexplored hexagonal perovskite family, but there are specific chemical features that are needed and are hard to find in combination.
Ceramic fuel cells are highly-efficient devices that can transform chemical energy into electrical energy and low yield emissions if powered by hydrogen, emerging to be a clean alternative to fossil fuels. Adding to the advantage of ceramic fuel cells, it can use hydrocarbon fuels like methane; hence, they can pose a ‘bridging’ technology, which is an essential asset in the move away from hydrocarbons towards a cleaner energy source. They can be utilized to power cars and homes. However, the high temperature of operation often leads to a short life span. Therefore it is essential to lower the working temperature for long-term maintenance, stability, safety, and cost.
Scientists from universities have been researching the potential for a new compound that may have the potential to overcome these issues for several years and, according to them, the discovery of a new chemical compound, which shows high conductivity at lower temperatures, marks to be a significant breakthrough.
It is undeniable that ceramic fuel cells are highly efficient. Still, the prime concern is that they operate at really high temperatures above 800 °C and, as a result, have a shorter lifespan and uses expensive components.
