A method of constructing a fuel cell includes a sintering technique that improves the structure and performance of the fuel cell elements. The method includes furnishing a fuel cell core comprising trilayers of anode, cathode, and interconnect layers, and trilayers of anode, cathode, and electrolyte layers. Each of the layers has a mixture of the respective anode, cathode, or interconnect ceramic material mixed with processing aid materials including a binder and a plasticizer, and, in the case of the interconnect mixture, optionally a flux. This partially fabricated fuel cell core is sintered to form a monolithic structure, the step of sintering being performed by heating the core at a heating rate of greater than about 40 degrees C. per minute to a sintering temperature of from about 1550 degrees to about 1600 degrees C., maintaining the core at the sintering temperature for a time of from about 5 to about 20 minutes, and cooling the sintered structure.
