Claim Text:
1. A fuel cell system comprising a media supply plate and a fuel cell stack directly stacked onto the media supply plate, wherein the media supply plate comprises at least one anode supply gas terminal, at least one cathode supply gas terminal, at least one anode waste gas terminal and at least one cathode waste gas terminal, wherein the terminals are each respectively connected to gas passages, each of which gas passages opening into at least one orifice proved on an upper side of the media supply plate, wherein the fuel cell stack is stacked onto the media supply plate so that the fuel cell stack partially covers the media supply plate, wherein gas passages connected to the anode supply and waste gas terminals form an anode pair, wherein gas passages connected to the cathode supply and waste gas terminals form a cathode pair, wherein the orifices of one of said anode and cathode pair is located in the area of the media supply plate covered by the fuel cell stack and the orifices of the other of said anode and cathode pair is located in the area of the media supply plate adjacent to the area covered by the fuel cell stack, wherein the fuel cell stack is disposed under a first cap that is mounted to the media supply plate, wherein the space under the first cap is divided into a supply space and a waste gas return space by the fuel cell stack, and wherein the at least one orifice of the anode or cathode pair that is located in the area of the media supply plate adjacent to the area covered by the fuel cell stack opens into the supply space, and the at least one other orifice of the anode and cathode pair that is located in the area of the media supply plate adjacent to the area covered by the fuel cell stack opens into the waste gas return space.
