METHOD FOR QUICKLY HEATING A FUEL CELL SYSTEM

The invention relates to a method for heating a fuel cell system (100a) for a motor vehicle (1000), having a fuel cell stack (1) with an anode section (2), a cathode section (3), at least one evaporator (4) for evaporating a fuel/water mixture, a reformer (5) for reforming the evaporated fuel/water mixture for use in the anode section (2) of the fuel cell stack (1), and at least one burner (6) for combusting a fuel-containing fluid, wherein the reformer (5) is arranged downstream of the at least one evaporator (4) in particular, and the at least one burner (6) is arranged upstream of the at least one evaporator (4) in particular. The at least one burner (6) is fluidically connected to the at least one evaporator (4) in order to supply fuel-containing fluid combusted in the at least one burner (6) from the at least one burner (6) to the at least one evaporator (4), and a fuel/water mixture source (7) for providing a fuel/water mixture for the at least one evaporator (4) is arranged upstream of the at least one evaporator (4). The invention additionally relates to such a fuel cell system (100a) and to a motor vehicle (1000) comprising the fuel cell system (100a).
