Abstract

The invention relates to a method for operating a fuel cell system (10) using a first operating mode, in which, when all of the fuel cell stacks (22, 26) are inactive, one fuel cell stack (22) is pre-heated using a coolant that is pre-heated by means of an electric heater (42) while bypassing all cooler circuits (58) of the active coolant circuits (14) via bypass lines (64) and the one pre-heated fuel cell stack (22) is activated in order to pre-heat an additional fuel cell stack (26) of the fuel cell system. Other operating modes for operating a fuel cell system are disclosed in additional embodiments.
