Power generating element

Abstract

Provided is a power generating element capable of obtaining a larger electromotive force by using humidity fluctuation in an environment. The power generating element generates power by using a humidity change due to water vapor in the environment. A first chamber shielded from the water vapor in the environment and a second chamber opened to the water vapor in the environment are separated by an ion-permeable membrane, and are each filled with an aqueous electrolytic solution including an aqueous solution of a deliquescent ionic compound. In addition, an electrode is provided in each of the first chamber and the second chamber. Here, the ion-permeable membrane is made of an electrolyte capable of conducting ions that have not been hydrated.
