Electrolysis of Water and Fuel Cell Operation

Electrolysis of Water By providing energy from a battery, water (H 2 O) can be dissociated into the diatomic molecules of hydrogen (H 2) and oxygen (O 2).This process is a good example of the the application of the four thermodynamic potentials.. The electrolysis of one mole of water produces a mole of hydrogen gas and a half-mole of oxygen gas in their normal diatomic forms.
