Solid Oxide Fuel Cells (SOFC) are precision electrochemical reactors. These cells consist of multiple layers of different ceramic materials, each with a different coefficient of thermal expansion. One major challenge in the manufacturing of these layers is to fire them without cracking or delaminating, caused by poor uniformity in the firing furnace. In addition to excellent thermal uniformity the firing furnace has to control the porosity of the ceramic. For firing steps above 1100°C, BTU offers the convection batch furnace and the continuous pusher furnace. For firing steps below 1100°C BTU offers a belt furnace system. BTU has proven it can deliver the very precise uniformity required with these three types of systems.
