FUEL CELL SYSTEM HAVING TWO FUEL CELL STACKS CONNECTED IN SERIES

摘要

The invention relates to a fuel cell system (10), comprising a first exothermally operated fuel cell stack (14) and a second not exothermally operated fuel cell stack (16), wherein a water molecule-containing anode waste gas (18) of the first fuel cell stack (14) can be supplied to the second fuel cell stack (16), and wherein hydrocarbons (20) can be admixed to the anode waste gas (18) by way of a feed line. According to the invention, the anode waste gas (18) of the first fuel cell stack (14) can be supplied to the second fuel cell stack (16) in the uncooled state. The invention further relates to a method for operating a fuel cell system.
