Hydrogen storage and production by redox of iron oxide for polymer electrolyte fuel cell vehicles

Pseudo-storage of hydrogen and its recovery by redox of iron oxide have been proposed as a new method of the storage and supply of hydrogen for PEFC vehicles. Among the additives to iron oxide tested, Al, Cr, Zr, Ga and V were the effective elements enhancing both the reduction with H 2 (storage of...

Description
Summary:Pseudo-storage of hydrogen and its recovery by redox of iron oxide have been proposed as a new method of the storage and supply of hydrogen for PEFC vehicles. Among the additives to iron oxide tested, Al, Cr, Zr, Ga and V were the effective elements enhancing both the reduction with H 2 (storage of H 2) and reoxidation with water (recovery of H 2) of the iron oxide (3Fe+4H 2O⇌Fe 3O 4+4H 2) at low temperatures (
