Abstract: The potential of a half cell has neither been obtained by calculation nor by experiment. The potential between a standard hydrogen electrode whose potential is assumed to be 0 V and a half cell whose potential is unknown is defined to be the potential of the half cell so that only a relative potential can be obtained. The potential of a standard hydrogen electrode is induced by the energy of reaction (H+ +e- →H) which produces mechanical work RT・lnV1/V0, and equals to an electrical energy F・△E°. Therefore, the absolute potential △E°of a standard hydrogen electrode is calculated to be 0.059 V from the equation F・△E°=RT・lnV1/V0, and the value is confirmed experimentally. It has been known that the potential of Daniell cell as well as Valtaic cell is casued by the energy of reaction of M+2nH+→M2n++nH2. Therefore the water cell in which water is used instead of electrolyte solution is possible to be produced.
