A bipolar plate for use in a fuel cell stack includes a first delimiting surface and a second delimiting surface that is arranged parallel to the first delimiting surface, wherein the delimiting surfaces are arranged spaced apart from one another and define an intermediate space, wherein the bipolar plate includes at least one fuel cell section having a flow field that has depressions that protrude into the intermediate space and is provided so as to make direct contact with a fuel cell, and the bipolar plate includes at least one cooling section that extends therefrom along the delimiting surfaces, wherein at least one heat pipe is arranged in the intermediate space and extends so as to transfer heat from the fuel cell section into the cooling section.

An engine for propelling an aircraft includes an annular fuel cell arrangement having at least one fuel cell, at least one electric motor couplable to the fuel cell arrangement, at least one fan couplable to the electric motor and a cowling having an inlet and an outlet nozzle. The fuel cell arrangement is arranged inside the cowling, the at least one fan is arranged between the inlet and the fuel cell arrangement inside the cowling, the electric motor is operable under consumption of electric power delivered by the fuel cell arrangement and the at least one fan is designed to produce a thrust force by creating an accelerated airflow at the outlet nozzle. The engine is extremely efficient and comprises a distinct low noise.

A drive unit includes a combustion chamber for combusting a fuel/air mixture, and a fuel cell device, wherein the fuel cell device includes at least one fuel cell, which in each case includes an anode that is couplable to a fuel line, a cathode that is couplable to an air source, and a fluid outlet and is arranged upstream of the combustion chamber. The combustion chamber further includes a combustion chamber inlet for supplying the fuel/air mixture, and a combustion chamber outlet for discharging exhaust gas, and the combustion chamber inlet is connected to the fluid outlet of the fuel cell device. In this way a hybrid drive unit can be provided which apart from mechanical power also generates electrical power at high efficiency.

A method for manufacturing a solid oxide fuel cell element by layer-wise buildup wherein at least one section of the element is built up by carrying out a step that at least includes the following at least once: applying a layer section of a particulate ceramic material with predefined dimensions onto a base layer in a predefined area and heating the layer section by means of a heat source such that the particles of the ceramic material connect to one another within the predefined dimensions. The solid oxide fuel cell element manufactured with the method is realized in one piece, as well as highly compact, and has a low weight.

A water generation system for the generation of water on board an aircraft comprises a fuel cell device having an exhaust for an exhaust gas, a condenser and an outflow valve for discharging cabin air, which is drawn off through the condenser due to the pressure difference between the cabin pressure and ambient pressure without extensive cooling circuits or pumps, for example. The condenser may be coupled to the exhaust such that the exhaust gas is cooled by cabin air, and the outflow valve is connected to the condenser and to the environment of the aircraft, such that, when the aircraft is at cruising altitude, the cabin air is drawn through the condenser and is discharged into the environment.
