Abstract
A fuel cell arrangement having fuel cells situated in the form of a fuel cell stack, which each contain an anode and a cathode and an electrolyte matrix situated between them, having an anode intake, which is provided on one side of the fuel cell stack, for the supply of fresh combustion gas to the anodes and an anode outlet for the discharge of consumed combustion gas from the anodes, the combustion gas being guided inside the fuel cells in a predetermined main flow direction past the anodes, having reformer units for converting a fuel supplied to the reformer units at a fuel inlet into reformer fuel, which is discharged from the reformer units at a reformer fuel outlet, the reformer units being situated between adjacent fuel cells in thermal contact therewith, and the reformer fuel outlet of the reformer units opening on the side of the fuel cell stack, on which the anode intake of the fuel cells is located, and having a fuel discharge system for distributing the fuel to be reformed to the individual reformer units. The reformer units have fuel inlets provided on the side of the fuel cell stack opposite to the anode intake and are permeated by the fuel to be reformed in counter-flow to the main flow direction of the combustion gas, and the fuel discharge system is provided on the side of the fuel cell stack opposite to the anode intake.
