Abstract
A method of making a solid oxide fuel cell (SOFC) includes forming a first sublayer of a first electrode on a first side of a planar solid oxide electrolyte and drying the first sublayer of the first electrode. The method also includes forming a second sublayer of the first electrode on the dried first sublayer of the first electrode prior to firing the first sublayer of the first electrode, firing the first and second sublayers of the first electrode during the same first firing step, and forming a second electrode on a second side of the solid oxide electrolyte.
Claims7
A method of making solid oxide fuel cells (SOFCs), comprising:
- providing a plurality of planar solid oxide electrolytes, each electrolyte having a first major side and a second major side;
- forming a first electrode on the first major side of each of the plurality of planar solid oxide electrolytes;
- stacking the plurality of solid oxide electrolytes into a stack such that the first major sides containing the first electrode of each pair of adjacent electrolytes in the stack face each other;
- and
- firing the stack, wherein the second major sides of each electrolyte in the stack lack an electrode during the step of firing.
A method of making a solid oxide fuel cell (SOFC), comprising:
- printing a wet first sublayer of a first electrode on a first side of a planar solid oxide electrolyte using a first ink;
- printing a second sublayer of the first electrode on the wet first sublayer of the first electrode prior to firing the first sublayer of the first electrode using a second ink having a lower viscosity than the first ink;
- firing the first and second sublayers of the first electrode during the same first firing step;
- and
- forming a second electrode on a second side of the solid oxide electrolyte.
