The project “Fuel cell system development for technical aviation” investigates a direct form of interconnection of fuel cells with drive shafts (H2-to-torque concept)

BETA investigates a direct form of interconnection of fuel cells with drive shafts (H2-to-torque concept). Using this concept, the topography of the electrical network can be simplified, thus saving material and weight. The elimination of the converters, which ensure a constant voltage supply to the consumers in conventional fuel cell systems, must be compensated using other means. 

In BETA, the HSU will develop an MCU system that is precisely tailored to the specific conditions in the application of the H2-to-torque architecture. This includes, among other things, power-dependent voltage regulation, redundancy, reliability, and safety mechanisms for the safe operation of such a system. Accordingly, HSU will develop concepts, build prototypes, test them and utilize them in a system network. In parallel, the behavior will be simulated to virtually test different MCU and MCU system architectures and to determine a suitable layout. 

The following definition of a MCU system will be used in the project: The MCU system is used for the electrical connection of system-integrated fuel cells to an electric drive. It comprises the control algorithms, electrical components and the communication interfaces for the electrical energy supply of the individual inductive powertrains with special consideration of the transient electrical terminal behavior of a PEM fuel cell.
