Solid oxide fuel cell stack design

Abstract:

A device comprising a first solid oxide fuel cell and a second solid oxide fuel cell. The first solid oxide fuel cell comprises a first anode, a first cathode and a first electrolyte, wherein the first electrolyte is positioned between and connected to the first anode and the first cathode. The second solid oxide fuel cell comprises a second anode, a second cathode and a second electrolyte, wherein the second electrolyte is positioned between and connected to the second anode and the second cathode. In this device the cathode distance between the first cathode and the second cathode is less than the anode distance between the first anode and the second anode.
