Researchers at the Georgia Institute of Technology have pinpointed a chemical that could allow polymer electrolyte membrane (PEM) fuel cells to operate at a much higher temperature without moisture, potentially meaning that polymer fuel cells could be made much more cheaply than ever before and finally run at temperatures high enough to make them practical for use in cars and small electronics.

Heat has always been a problem for fuel cells. 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.
