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.
