Claim:
1. A fuel cell arrangement, comprising: at least one horizontally arranged fuel cell stack, which has a plurality of fuel cells, each of which includes an anode, a cathode and an electrolyte arranged between the anode and cathode; at least one fuel gas feed device to feed fuel gas to the anodes of the fuel cells; at least one anode gas withdrawal device to withdraw an anode waste gas from the anodes; at least one cathode gas feed device to feed cathode gas to the cathodes of the fuel cells; at least one cathode gas withdrawal device to withdraw cathode exhaust from the fuel cells; and at least one return device to return at least part of at least one of the anode waste gas and the cathode exhaust to the cathodes of the fuel cells; wherein the at least one return device includes at least one catalytic burner with catalyst material for burning of residual combustible gas contained in the anode waste gas, which is arranged laterally next to the fuel cell stack; and wherein the fuel cell arrangement is enclosed by a gas-tight protective housing and the catalytic burner is arranged on the inside of a side wall of the protective housing, and the catalytic burner is accessible from the outside through the protective housing via at least one cleaning opening, via which the catalyst can be replaced.
