Metal Hydrides as a Source of Fuel for Vehicular Propulsion 690232

Studies of the equilibrium relationships and kinetics of the reversible reaction of hydrogen with magnesium-nickel and magnesium-copper alloys indicate that such systems have properties that may form the basis of a convenient and inexpensive method of storing hydrogen. This unique hydrogen storage technique offers the possibility of utilizing this clean and potentially economical fuel for motor vehicle propulsion. A vehicle propelled by a hydrogen-fueled internal-combustion engine would produce an exhaust that is inherently free of the hydrocarbon, carbon monoxide, and carbon dioxide pollutants that are major contributors to the atmospheric pollution problem in urban areas. The characteristics of this vehicular propulsion concept have been estimated and indicate that the hydrogen engine is potentially superior in performance to other inherently hydrocarbon-free propulsion concepts such as battery and fuel cell powered electric drives.
