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.
Improper pH Balance. Chlorine is a chemical added to swimming pools to kill bacteria that can build up over time and lead to a discoloration of the water. Green water is most often a sign of algae, not necessarily bacteria, but different pools have different bacteria that can affect the water.
