Most fuel cells in the world today run on hydrogen. However, as the fuel gets more complex, this oxidation process becomes vastly more complicated. Once carbon atoms are in the fuel, carbon monoxide poisoning of typical fuel cell catalysts becomes problematic.
Bromine dissociates in water in the same manner as chlorine, by forming hypobromous acid and the hypobromite ion. Hypobromous acid is a weak acid that partially dissociates to form a hydrogen ion and a hypobromite ion.
Hydrogen + Oxygen = Water The simple statement that water is made from hydrogen and oxygen doesn't give us a very clear picture of what really goes into the creation of a molecule of water. A quick look at the chemical equation for the formation of water tells us more.
