Method of making a fuel cell device
An electrode layer is provided by forming first and second sublayers containing input passages and exhaust passages, respectively. Electrode material is positioned around a first portion of first and second pluralities of spaced-apart removable physical structures to at least partially surround the structures thereby forming an active cell portion in each sublayer. Ceramic material is positioned around second portions to form a passive support structure in each sublayer. Another passive support structure is formed opposite the first, with the active cell portion therebetween. The sublayers are laminated, the physical structures are pulled out, and the laminated sublayers are sintered to reveal spaced-apart input passages from one end of the layer through the active cell portion, and spaced-apart exhaust passages from the active cell portion to a side of the layer adjacent the other end, the input and exhaust passages embedded in and supported by the sintered electrode and ceramic materials.
