Abstract: 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.

Abstract: The invention relates to a method of making fuel cell devices. Anode and cathode layers are applied on respective first and opposing second sides of a first portion of a first green ceramic layer, and a second green ceramic layer of thickness approximately equal to that of the anode and cathode layers is applied on a second portion of each of the first and second sides of the first green ceramic layer. A sacrificial layer is applied over each of the anode, cathode and second green ceramic layers, and a third green ceramic layer is applied over the sacrificial layers. The layered structure is heated to sinter all the layers and burn out the sacrificial layers. A pair of gas passages is thus formed with a thick sintered ceramic therebetween as a passive supporting portion and an anode, thin electrolyte and cathode therebetween as an active portion of the device.

Abstract: A method of making a fuel cell device comprises forming a green stacked structure to provide an internal active section of intervening green layers of ceramic material separating anode layers from cathode layers and sacrificial layers of organic material adjacent each of the anode and cathode layers opposite the intervening green layers, and a non-active section of the green layers substantially surrounding the active section. The sacrificial layers are sized to provide internal gas passages in the active section for feeding gases to the internal anodes and cathodes, and the sacrificial layers are coupled to edges of the structure to couple each of the internal gas passages to an inlet and an outlet of the device. The green stacked structure is heated to bake out the organic material to form the passages and to sinter together the green layers in the active and non-active sections.
