Production & Use of Hydrogen by Electrochemical Reactors

In the first part, a PEM (polymer electrolyte membrane) electrolysis cell is shown, in which water can be split into protons and oxygen by electrical energy. The protons pass through a cation exchange membrane to the cathode, where they are reduced to hydrogen by electrons. The hydrogen produced can then be stored temporarily for a longer period, for example in tanks. The stored energy (in the form of hydrogen) can be converted back into electrical energy via a PEM fuel cell. Here, the reversible electrolysis process runs in reverse, converting hydrogen and oxygen into water and electricity. The electricity can then be used to power a model electric truck.
