Hydrogen fuel works on the principle of making water by H2 and O2 !!
At the cathode (negative electrode): H2(g)-2e →2H+(aq)
At the anode (positive electrode): 4H+(aq) + O2(g) + 4e– → 2H2O(g)
* As there is no harmful gasses evolve, and only water is formed so these cells are clean and healthy to use !!
(ADDITIONAL)
and remember these are 90-98% efficient !! as compare to petrol or diesel that are 50-60% efficient !!
Hydrogen fuel cells are used in Space programs to make pure water and other purposes !!
