   In new research led by the University at Buffalo, researchers describe   
   how iron can be combined with nitrogen and carbon to produce a new   
   catalyst that is efficient, durable, and inexpensive - the three main   
   objectives the U.S. Department of Energy (DOE) has identified for fuel   
   cell research.   
      
   Iron-based catalysts are less costly alternatives because iron is   
   abundant and inexpensive. But it does not perform as well as platinum,   
   especially because it lacks the durability to withstand the highly   
   corrosive and oxidative environments inside fuel cells.
