Electromotive force generating device

Abstract

The electromotive force generating device 10 of the present invention includes: a power generation mechanism 14 having an electrolyte-containing body 11 containing an electrolyte solution, a positive electrode 12, and a negative electrode 13, wherein the positive electrode 12 and the negative electrode 13 are in contact with the electrolyte-containing body 11 to generate an electromotive force; and a container 16, which together contain the entire or a portion of the electrolyte-containing body 11 and the liquid in a sealed state. Therefore, the electromotive force generating device 10 maintains the humidity inside the container 16 at a certain level, thereby suppressing the decrease in output current and output voltage caused by a decrease in the humidity of the gas environment.
