Abstract:
1. A solid oxide fuel cell assembly comprising: a stack of alternating planar solid oxide fuel cells and gas separator plates, each solid oxide fuel cell comprising an anode layer, a cathode layer, and an electrolyte layer between the anode and cathode layers, wherein each gas separator plate is disposed between the anode layer of a first adjacent solid fuel cell and the cathode layer of a second adjacent fuel cell, and comprises a separator body with an anode-facing side and a cathode-facing side and with paths of electrically conductive material therethrough from the anode-facing side to the cathode-facing side, wherein the electrically conductive material forming at least part of the length of each path is a silver-glass composite comprising no more than 40 wt % glass, and wherein the separator body comprises a different material from that of said paths, the different material being less electrically conductive than said electrically conductive material.
