Abstract
The invention relates to a fuel cell system comprising a first exothermally operated fuel cell stack and a second non-exothermally operated fuel cell stack, wherein anode waste gas containing water molecules from the first fuel cell stack can be supplied to the second fuel cell stack, and wherein hydrocarbons can be admixed to the anode waste gas by way of a feed line. According to the invention, it is contemplated that the anode waste gas of the first fuel cell stack can be supplied to the second fuel cell stack in an uncooled state. The invention further relates to a method for operating a fuel cell system.
