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.
It may explode. That is, hydrochloric acid and calcium give Calcium Chloride and hydrogen gas and heat. In practice, it would give Calcium ions and Chloride ions in solution.If you had exactly the right amount of each, you could then evaporate the water and have calcium chloride salt left over.hat is, hydrochloric acid and calcium give Calcium Chloride and hydrogen gas and heat.
