A printed circuit board for transmitting electrical energy and for signal transmission includes electrical conductor tracks coupled to the printed circuit board wherein the electrical conductor tracks include a first electrical conductor track with a superconducting material. The first electrical conductor track is designed to provide electrical energy directly to a power electronics system. The electrical conductor tracks include a second electrical conductor track which is designed to provide a signal transmission to a signal electronics system. A system is disclosed having such a printed circuit board.

An electrical energy storage system includes electrochemical energy storage cells for collecting, supplying and storing electrical energy, a contacting device for contacting the energy storage cells, and temperature sensors for monitoring temperature of individual energy storage cells. The electrochemical energy storage cells include a first and second electrical terminal, the contacting device including conductors. A first contacting element connects the first electrical terminal of each cell and a first conductor of the contacting device. A second contacting element connects the second electrical terminal of each cell and a second conductor of the contacting device. The temperature sensors include a thermocouple having a first element from a first metal material and a second element from a second metal material. The first element is connected to one of the terminals or the body of the energy storage cell and the second element is connected to the first element or the body of the energy storage cell.

In order to improve usability of hybrid or fully electric aircraft, a fuel cell having improved efficiency and increased volume/weight specific energy density is provided. The fuel cell has a self-supporting membrane structure that is formed as a triply periodic level surface, which separates a first cavity supplied with gaseous fuel from a second cavity supplied with gaseous oxidizer in a gas-sealed manner while connecting the cavities in an ion-conductive manner.

Fuel cell and fuel cell system for an aircraft

An interconnector plate for a fuel cell and a fuel cell system for an aircraft. For better extraction of the energy generated by the fuel cell, an interconnector plate can be attached by form fit to fixing studs of the fuel cell by retaining eyes. The interconnector plate may additionally be secured using glass solder. In preparation for a higher power density, a fuel cell can be produced in ceramic by 3D-printing and has an improved power density because of its helical shape.

A fuel cell to provide a higher power density. The fuel cell can be produced by 3D printing in ceramic and has an improved power density by virtue of its spiral shape. In order to better extract the energy generated by the fuel cell, an interconnector sheet can be fastened positively to fastening knobs of the fuel cell by holding eyes. In addition, the interconnector sheet can be fixed by glass solder.

An energy supply device for reliably supplying energy to electrical loads, provides the energy supply by constant voltage sources. The number of constant voltage sources corresponds to the number of electrical loads. The energy supply device has a deactivatable balancing network. In this case, only the compensating currents are conducted via the balancing network, while the energy supply is provided via a direct electrical connection between the constant voltage source and the load. If a fault occurs, the balancing network can be deactivated. Faults in one branch thus do not affect the level of reliability of the energy supply in the remaining branches. After a faulty component has been located and isolated, the sources that are still intact, and the intact loads, can be brought back into operation by suitably configuring the balancing network. The availability of the drive system can thus be increased.
