Fuel cells get chemical boost

HEAT HAS ALWAYS BEEN A PROBlem for fuel cells. There's usually either too much, as with ceramic fuel cells for certain portable uses, such as automobiles or electronics, or too little as with polymer fuel cells to be efficient.

While polymer electrolyte membrane (PEM) fuel cells are the most promising fuel cells for portable use, their low operating temperature and low efficiency have blocked their jump from promising technology to practical usage.

In an effort to change that, researchers at the Georgia Institute of Technology pinpointed a chemical that could allow PEM fuel cells to operate at a much higher temperature without moisture, potentially meaning researchers could make polymer ...
