Fuel cell and fuel cell system for an aircraft

A fuel cell for a fuel cell system, the fuel cell comprising:

• a first fuel cell region that forms a first gas channel for a flow of a fuel through the first gas channel;
• a second fuel cell region that forms a second gas channel for a flow of an oxidizer through the second gas channel;
• a first distribution tube comprising:
• a gas supply region for providing the fuel to the first gas channel of the first fuel cell region;
• and
• a gas discharge region for discharging, from the first gas channel of the first fuel cell region, reaction product and/or any of the fuel that is unconsumed;
• and
• a second distribution tube comprising:
• a gas supply region for providing the oxidizer to the second gas channel of the second fuel cell region;
• and
• a gas discharge region for discharging, from the second gas channel of the second fuel cell region, reaction product and/or any of the oxidizer that is unconsumed;
• and
• wherein the first and second gas channels that are formed, respectively, by the first and second fuel cell regions both extend in a circumferential direction around a construction axis;
• wherein, when viewed along the construction axis, the first and second distribution tubes are both at least partially surrounded by both of the first and second gas channels of the first and second fuel cell regions, respectively;
• wherein the first gas channel comprises a gas inlet region and a gas outlet region, the gas inlet region and the gas outlet region of the first gas channel being arranged such that, when a further first fuel cell region is arranged or formed offset from the first fuel cell region along the construction axis, the gas outlet region of the first gas channel is aligned with and/or fluidically connected to a gas inlet region of a further first gas channel of the further first fuel cell region, the further first gas channel being configured for receiving the flow of the fuel from the first gas channel;
• wherein the second gas channel comprises a gas inlet region and a gas outlet region, the gas inlet region and the gas outlet region of the second gas channel being arranged such that, when a further second fuel cell region is arranged or formed offset from the second fuel cell region along the construction axis, the gas outlet region of the second gas channel is aligned with and/or fluidically connected to a gas inlet region of a further second gas channel of the further second fuel cell region, the further second gas channel being configured for receiving the flow of the oxidizer from the second gas channel;
• wherein the fuel cell is divided into subsections that each contain a respective portion of each of the first and second gas channels of the first and second fuel cell regions, the first and second distribution tubes being connected for providing, within each of the subsections and in parallel, the respective portion of each of the first and second gas channels contained therein with the fuel and the oxidizer, respectively.
