Method of making a fuel cell device
A monolithic fuel cell device is provided by forming anode and cathode layers by dispensing paste of anode or cathode material around pluralities of spaced-apart removable physical structures to at least partially surround the structures with the anode or cathode material and then drying the paste. An electrolyte layer is provided in a multi-layer stack between the cathode layer and the anode layer thereby forming an active cell portion. The multi-layer stack is laminated, and then the physical structures are pulled out to reveal spaced-apart active passages formed through each of the anode layer and cathode layer. Finally, the laminated stack is sintered to form an active cell comprising the spaced apart active passages embedded in and supported by the sintered anode material and sintered cathode material.
