Will future Hydrogen Fuel Cells use Iron instead of Platinum

This whole H2 is more dangerous than gasoline will be one hard brain bug to get rid of.

• Hydrogen disperses quickly. Being the lightest element (fifteen times lighter than air), hydrogen rises and spreads out quickly in the atmosphere. So when a leak occurs, the hydrogen gas quickly becomes so sparse that it cannot burn. Even when ignited, hydrogen burns upward, and is quickly consumed, as shown in the Hindenburg picture. By contrast, materials such as gasoline and diesel vapors, as well as natural gas are heavier than air, and will not disperse, remaining a flammable threat for much longer.
• Hydrogen is non-toxic. Hydrogen is a non-toxic, naturally-occurring element in the atmosphere. By comparison, all petroleum fuels are asphyxiants, and are poisonous to humans.
• Hydrogen combustion produces only water. When pure hydrogen is burned in pure oxygen, only pure water is produced. Granted, that’s an ideal scenario, which doesn’t occur outside of laboratories and the space shuttle. In any case, when a hydrogen engine burns, it actually cleans the ambient air, by completing combustion of the unburned hydrocarbons that surround us. Compared with the toxic compounds (carbon monoxide, nitrogen oxides, and hydrogen sulfide) produced by petroleum fuels, the products of hydrogen burning are much safer.
• Hydrogen can be stored safely. Tanks currently in use for storage of compressed hydrogen (similar to compressed natural gas tanks) have survived intact through testing by various means, including being shot with six rounds from a .357 magnum, detonating a stick of dynamite next to them, and subjecting them to fire at 1500 degrees F. Clearly, a typical gasoline tank wouldn’t survive a single one of these tests.
