ELECTRODE DEVICE
An electrode device 1 includes a first electrode 2, a second electrode 3, and an ion-conducting medium 7 extending over and in contact with the first electrode 2 and the second electrode 3. The ion-conducting medium 7 is made of a bicontinuous microemulsion including a water phase as a continuous phase and an oil phase as a continuous phase. At least one of the water phase and the oil phase is a gel.
