A Solid Oxide Fuel Cell (SOFC) system has been described in a filed patent, comprising a chamber enclosed by a material with a high coefficient of thermal conductivity, enabling efficient electro-chemical energy generation at SOFC operating temperatures. The system includes a cell with an anode and cathode in thermal communication with the material, along with additional components such as an electrolyte, combustor, cold start module, reformer, and recuperator for enhanced functionality.

The method for operating the SOFC system involves utilizing the volume of material enclosing the chamber with high thermal conductivity to facilitate the electro-chemical energy generation process at the desired operating temperature. The method includes steps such as ensuring thermal communication between the cell components and the material, combusting spent fuel and exhaust, catalyzing fuel supply, and heating air delivered to the system. By incorporating these steps and utilizing materials with specific thermal conductivity properties, the SOFC system can operate efficiently and effectively for various applications.
