Problem Heat from Fuel Cells, solved?

08/29/2005 7:38 AM

As stated by the Georgia Tech news release, "There's usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient."

Well it seems there's hope to solving this problem.
The researchers are using triazole to replace water in fuel cells. It is a stable chemical that raises fuel cell temperatures to 120 degrees Celsius, which keeps the heat in a ceramic fuel cell to a reasonable temperature below the normal operating temp of 800 degrees Celsius.
The article goes into greater detail, but Dr. Meilin Liu, a professor in the School of Materials Science and Engineering at Georgia Tech says, "Triazole will greatly reduce many of the problems that have prevented polymer fuel cells from making their way into things like cars, cell phones and laptops. It's going to have a dramatic effect."

correction: pem fuel cells only

This change only effects polymer fuel cells. Ceramic fuel cells have not been tested with this and I would venture to say this chemical would improve on any of the ceramic fuel cell characteristics.
