摘要： Making a larger difference in water activity between electrodes elevates an output voltage of an electrochemical element. The electrochemical element includes a solid electrolyte membrane 5 made of a solid electrolyte and possessing a hydrogen ion conductivity, a first electrode 6 formed on one side of the solid electrolyte membrane 5 and functioning as a catalyst and possessing a hydrophilic property, and a second electrode 7 formed on the other side of the solid electrolyte membrane 5 and functioning as a catalyst and possessing a water-repellent property.
