A burner device having a burner chamber ( 26 ) filled at least partially by a porous body ( 28 ), an evaporation zone ( 12 ) upstream of the burner chamber ( 26 ) for evaporating liquid fuel supplied via a fuel inlet line ( 16 ), an igniter ( 30 ) for igniting a combustion mixture of evaporated liquid fuel and combustion air supplied via a combustion air inlet line ( 18 ) to the evaporation zone ( 12 ) as well as an exhaust discharge ( 38 ) downstream of the combustion chamber ( 26 ). A mixing zone ( 20 ) is disposed between the evaporation zone ( 14 ) and the combustion chamber ( 26 ) in which fuel gas is introduced via a fuel gas inlet line ( 22, 24 ) and is mixed with the combustion air and/or the combustion mixture. The burner device can be used as an afterburner in a fuel cell stack.
