According to foreign media reports, researchers at the University of Aberdeen in Scotland have discovered a new type of chemical compound that may revolutionize fuel cell technology and help reduce global carbon emissions. This chemical compound is called "hexagonal perovskites" and may be the key to unlocking the potential of ceramic fuel cells.
Ceramic fuel cells are high-efficiency batteries that can convert chemical energy into electrical energy. If hydrogen is used as an energy source, the emissions of such batteries will be very low and become a clean alternative energy source for fossil fuels. Another advantage of ceramic fuel cells is that they can use hydrocarbon fuels such as methane, which means that they can be used as a "transitional" technology, from the use of hydrocarbons to use cleaner energy.
This type of battery can be used to power cars and homes, but operating at high temperatures results in a short service life. Reducing the operating temperature is essential to ensure long life, stability, safety and low cost of ceramic fuel cells.
Scientists at the University of Aberdeen have been studying a new compound that may overcome the above problems for many years, and this new chemical compound still shows high conductivity at low temperatures, which is a major breakthrough.
Professor Abbie McLaughlin, director of research at the Department of Chemistry at the University of Aberdeen, led the study, explaining: "Ceramic fuel cells are very efficient, but the problem is that they can only work at high temperatures above 800 degrees Celsius. Because of this, this kind of The battery life is very short and expensive components are required. "
"For many years, we have been searching for compounds that can overcome these problems in the relatively unexplored hexagonal perovskite family, but it is difficult to find compounds that gather the specific chemical characteristics required. For example, it is necessary to find hydrogen in fuel cells Compounds that work steadily in an oxygen environment but have very low conductivity. "
"We finally found a double proton and oxide ion conductor that can successfully operate at a lower temperature (500 degrees Celsius), thus solving the above problem."
Gate Valves are called "full-flow" valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
