Abstract:
1. A method of making a fuel cell device comprising: providing a first green ceramic layer having a first portion that will serve as an active electrolyte portion of the fuel cell device and a second portion that will serve as a passive supporting portion of the fuel cell device; applying an anode layer on the first portion of a first side of the first green ceramic layer and applying a cathode layer on the first portion on an opposing second side of the first green ceramic layer; applying a second green ceramic layer on the second portion of each of the first and second sides of the first green ceramic layer, wherein a thickness of the second green ceramic layers is approximately equal to a thickness of the anode layer and the cathode layer; applying a sacrificial layer over each of the anode and the cathode layers and second green ceramic layers; applying a third green ceramic layer over each of the sacrificial layers, wherein the first, second and third green ceramic layers are configured to be non-conductive to electrons, and the anode and cathode layers are configured to be conductive to electrons; and heating to a temperature sufficient to sinter all the layers and burn out the sacrificial layers to form a pair of gas passages with a thick sintered ceramic therebetween in the passive supporting portion and an anode, thin electrolyte and cathode therebetween in the active electrolyte portion.
