Electrolysis reactions, general principles

As is mentioned in Section 3.4, the use of hydrogen gas as a source of clean energy is gaining attention. Based on the ion selectivity of CSZ, hydrogen gas can be produced by electrolysis of H2O gas. In principle, the reverse reaction of the fuel cell shown in Fig. 3.5, can be used for this purpose, that is, the electrochemical extraction of hydrogen from H2O gas by an external current. In Fig. 3.7 the equipment for the electrolysis of HjO gas, devised by General Electric Co., is shown.
