Electrolysis of water is using electricity to split water into oxygen (O 2) and hydrogen (H 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient 'tanks' or. . In 1789, and used an electrostatic machine to make electricity that was discharged on gold electrodes in a . In 1800, invented the ,. . In pure water at the negatively charged cathode, a reaction takes place, with electrons (e ) from the cathode being given to hydrogen cations to form hydrogen gas. At the positively charged anode, an reaction occurs, generating oxygen gas. . Electrolysis in pure water consumes/reduces H at the cathode and consumes/oxidizes hydroxide (OH ) at the anode. This can be verified by adding a to the water: Water near the cathode is basic while water near the anode is. . About five percent of hydrogen gas produced worldwide is created by electrolysis. The vast majority of current industrial hydrogen production is from in the process, or from the partial oxidation of or heavy hydrocarbons. The. . A DC electrical power source is connected to two , or two plates (typically made from an inert metal such as or ) that are placed in the water.

The basic principle of electrolysis is to split water into oxygen and hydrogen with the help of electricity. The splitting occurs in two partial reactions that take place at the two electrodes – cathode (-) and anode (+) – in the electrolysis cell. In practice, electrolysers consist of several interconnected electrolysis cells, also called stacks.
The basic principle of electrolysis is to split water into oxygen and hydrogen with the help of electricity. The splitting occurs in two partial reactions that take place at the two electrodes – cathode (-) and anode (+) – in the electrolysis cell.
The basic reaction of water electrolysis is as follows in Eq. (1). (1) 1 H 2 O + Electricity (237. 2 kJ mol − 1) + Heat (48. 6 kJ mol − 1) ⟶ H 2 + 1 2 O 2 The above reaction (Eq. (1)) requires 1.23 V theoretical thermodynamic cell voltage to split the water into hydrogen and oxygen at room temperature.
The process of splitting water into hydrogen and oxygen with the help of electricity has been used since the beginning of 19 th century . One important precondition for hydrogen electrolysis is that both water and electricity sources do not conflict with sustainability standards (see our EESG Framework for Sustainable Power-to-X).
The electrolyzer system primarily depends on fundamental thermodynamic parameters like mass, energy, and electric charge conversion along with thermodynamic equilibrium and state due to the interdisciplinary nature of the water electrolysis reaction.
The electricity must come 100% from renewable energies to guarantee CO 2 -free hydrogen production . Sustainable water supply must also be ensured: The water input should not compete with crucial processes such as local drinking water supply or agricultural irrigation. How does electrolysis work?
