Abstract

A solid state ionic device includes a dense electrolyte sandwiched between two porous electrodes. In one embodiment, the device is anode supported and the cathode is formed of a porous three-dimensional solid phase structure having an electrocatalytic phase of a plurality of electrocatalytic particles (14) and an ionic conducting phase of a plurality of ionic conductor particles (16). The mean or median size of the electrocatalytic particles is larger than the mean or median size of the ionic conductor particles. The device may further include a long range electronic conducting layer of lantham cobaltate or other electronically conducting material.
