Title: Method for operating a fuel cell facility, and fuel cell facility
Inventor: MERKEL CHRISTIAN
IPC: H01M8/247
Filed: 2000-02-28
Granted: 2008-05-06
Abstract: The thermal efficiency of a fuel cell facility (1) results from the useful heat which is generated per quantity of fuel. Heat which is radiated from the fuel cell facility (1) into the environment is lost and cannot be utilized. The invention describes a method which minimizes the radiation of heat from the fuel cell facility (1). In this method, the air for operation of the fuel cells is passed into a housing (2) which surrounds heat-radiating components of the fuel cell facility (1). The air flows around the components, absorbs the heat which is radiated and delivers it to the fuel cell block (4), where the heat is emitted to cooling water which cools the fuel cell block (4) and transfers the heat to water of a heating-water circuit (4).
