Abstract
The present disclosure provides an electric power generation element with improved power generation efficiency. An electric power generation element according to the present disclosure includes a first electrode, a second electrode, and a solid electrolyte layer. The first electrode splits water. The solid electrolyte layer is disposed between the first electrode and the second electrode. A resistance value R of the solid electrolyte layer satisfies R<50Ω. The solid electrolyte layer conducts, for example, ions generated by the splitting of water at the first electrode toward the second electrode.
Claims17
An electric power generation element, comprising:
- a first electrode that splits water;
- a second electrode;
- and
- a solid electrolyte layer disposed between the first electrode and the second electrode,
- wherein
- catalytic activity of the first electrode with respect to water splitting at a predetermined temperature is higher than catalytic activity of the second electrode with respect to water splitting at a predetermined temperature;
- and
- a resistance value R of the solid electrolyte layer satisfies R<50Ω.
An electric power generation method comprising:
- placing an electric power generation element including a first electrode, a second electrode, and a solid electrolyte layer disposed between the first electrode and the second electrode in an environment in which water is present, and splitting water by using the first electrode to generate ions;
- conducting the ions toward the second electrode in the solid electrolyte layer;
- oxidizing or reducing the ions in the second electrode to generate water;
- and
- generating an electric current outside the electric power generation element,
- wherein
- a resistance value R of the solid electrolyte layer satisfies R<50Ω in the electric power generation element.
