METHOD FOR OPERATING A FUEL CELL FACILITY AND CORRESPONDING FUEL CELL FACILITY

摘要

A method for operating a fuel cell plant and a fuel cell plant are provided. The thermal efficiency of a fuel cell plant results from the useful heat which is generated per quantity of fuel. Heat which is radiated from the fuel cell plant into the environment is lost and cannot be utilized. The method minimizes the radiation of heat from the fuel cell plant. Air for operation of the fuel cells is passed into a housing which surrounds heat-radiating components of the fuel cell plant. The air flows around the components, absorbs the heat which is radiated and delivers it to the fuel cell block, where the heat is emitted to cooling water that cools the fuel cell block and transfers the heat to water of a heating-water circuit.
