Cubic Zirconia Equals Better Fuel Cells?


Posted July 17, 2007 - By John Manalang

 They say diamonds are forever…

We and three researchers at UC Davis say that cubic zirconias are the same…for us nerds at least.

Engadget reports that Zuhair Munir, Umberto Anselmi-Tamburini and Sangtae Kim developed a method in using the diamond stimulant to cool hydrogen fuel cells by nearly 90 percent. By incorporating a cubic zirconia into their mix, the trio at UC Davis was able to run their cells between 122 and 212 degrees Fahrenheit, where typically it takes about 1,500 and 1,800 degrees.

How does it work? And what are fuel cells typically used for? Find out after the jump!


 How does it cool so fast? Well here’s a little ‘Bill Nye’ for ya: The zirconia cooling method works because conduction moves via ‘protonic movement’, which proves to be more efficient than ‘ionic mobility’. The more efficient and faster we can cool hydrogen fuels, to more work load it can do. K, class dismissed.

Fuel cells are used for our power plants, auxiliary power source, some laptops, and our friendly hybrid cars.
