Abstract
A fuel cell system for aircraft with a passenger cabin comprises a fuel cell. The fuel cell comprises a first inlet connection, a first outlet connection, a cathode side and an anode side, wherein the first inlet connection is formed as the inlet connection of the cathode side and wherein the first outlet connection is formed as the outlet connection of the cathode side. In addition, the fuel cell system is designed in such a way that at the first inlet connection, a gas with a pressure is applied, which corresponds to an air pressure in the passenger machine.
Claims26
An aircraft with a passenger cabin and a fuel cell system, wherein the fuel cell system comprises:
- a fuel cell, wherein the fuel cell comprises:
- a first inlet connection;
- a first outlet connection;
- a cathode side;
- and
- an anode side;
- wherein the first inlet connection is formed as an inlet connection of the cathode side;
- wherein the first outlet connection is formed as an outlet connection of the cathode side;
- and
- wherein the fuel cell system is designed in such a way that at the first inlet connection, a gas with a pressure is applyable, which corresponds with an air pressure in the passenger cabin.
An aircraft comprising a water supply system, the water supply system comprising:
- a fuel cell system, the fuel cell system comprising:
- a fuel cell, wherein the fuel cell comprises:
- a first inlet connection;
- a first outlet connection;
- a cathode side;
- and
- an anode side;
- wherein the first inlet connection is formed as an inlet connection of the cathode side;
- wherein the first outlet connection is formed as an outlet connection of the cathode side;
- and
- wherein the fuel cell system is designed in such a way that at the first inlet connection, a gas with a pressure is applyable, which corresponds with an air pressure in the passenger cabin;
- wherein the water supply system further comprises:
- a fuel tank;
- a converter;
- and
- a heat exchanger,
- wherein the converter is designed as a DC/DC/AC converter;
- wherein the heat exchanger is designed in such a way that by it, heat produced by the fuel cell system can be conducted away;
- and
- wherein the fuel tank is designed in such a way that by it, fuel can be supplied to the fuel cell system.
A method for operating a fuel cell system in an aircraft with a passenger cabin, wherein the fuel cell system comprises a fuel cell, wherein the fuel cell comprises a first inlet connection, a first outlet connection, a cathode side and an anode side, wherein the first inlet connection is formed as the inlet connection of the cathode side and wherein the first outlet connection is formed as the outlet connection of the cathode side, wherein the method comprises:
- applying, at the first inlet connection, a gas with a pressure, which pressure corresponds with an air pressure in the passenger cabin;
- placing a negative pressure on the outlet connection of the fuel cell;
- and
- suctioning gas into the cathode side of the fuel cell by the negative pressure.
