Title: Low circumferential voltage gradient self supporting electrode for solid oxide fuel cells

Patent ·
OSTI ID:6912579

This patent describes a porous, self-supporting, axially elongated electrode structure for a solid oxide electrolyte cell, where the electrode comprises a metal oxide material having at least two chambers through its axial length, and the chambers separated by electrode material defining a structural member. The electrode structure has a contacting layer of solid electrolyte on its outer surface, and an outer layer of porous electrode on top of the electrolyte, where the outer electrode and the electrolyte have a discontinuity containing a narrow electronically conductive interconnect which extends an axial length along the self-supporting inner electrode. The electrons at points in the inner electrode farthest from the interconnect can travel to the interconnect through the structural member.
