- the reaction at the gas electrode is a reaction that occurs between hydrogen or a hydrogen-containing compound in the gas and protons and electrons, and the electrode reaction proceeds in a place where these three coexist. Since these three are usually separated into a gas phase, an electrolyte phase, and an electron conducting phase, respectively, such a reaction field is called a three-phase interface.
- the three-phase interface should only have a one-dimensional spread, considering its component forces, but the reaction field where an electrode reaction can occur must have at least a two-dimensional spread. Must. Therefore, it is considered that the reaction field in which the electrode reaction actually occurs has some extent near the three-phase interface at the interface between the gas phase and the electron conducting phase or at the interface between Z and the gas phase and the electrolyte phase. . That is, in the former combination, Some reaction intermediates related to hydrogen exist at the interface with the gas phase, through which the electrode reaction can proceed. In the latter, an electrode reaction occurs because the electrolyte phase, which originally has no electron conductivity, locally generates some degree of electron conductivity near the electron conduction phase at the interface with the gas phase. Can be considered.
