New Membrane Could Improve Fuel Cell Efficiency
A new type of membrane based on tiny iron particles appears to address one of the major limitations exhibited by current power-generating fuel cell technology. While there are many types of fuel cells, in general they generate electricity as the result of chemical reactions between an external fuel -- most commonly hydrogen -- and an agent that reacts with it. The membrane that separates the two parts of the cell and facilitates the reaction is a key factor in determining the efficiency of the cell.
Researchers at Duke University's Pratt School of Engineering have developed a membrane that allows fuel cells to operate at low humidity and theoretically to operate at higher temperatures.
