Hydrogen-based propulsion solutions: a definition

Hydrogen-based drive solutions can generally be divided into the following categories:


  • Power generation from hydrogen using fuel cells
  • Power generation from hydrogen using a combustion engines
  • Direct use of hydrogen via combustion engine as a pure diesel substitute

The latter does not require electrification. The other two variants are topologically serial hybrids. In this case, the higher efficiency of the electric drive train and the coverage of the peak power by a (small) battery enable the combustion engine or fuel cell to be designed with a smaller output.


ARADEX offers high-voltage components for use with both fuel cells and combustion engines.

Main potentials of hydrogen-based drive solutions


We see hydrogen as one of the main energy carriers of the future. However, hydrogen will remain expensive for a relatively long time. For this reason, we see our main task in subsystems for energy conversion and drive technology, which achieve the best possible overall efficiency in your specific application. We answer the question of fuel cell or combustion engine with “both”.


The fuel cell has the better efficiencies compared to combustion engines and will continue to have them in the future. It is also low-noise and produces no exhaust gases apart from steam. For this purpose, we offer our highly efficient DC/DC converters to achieve the coupling to HV batteries in an optimal way.


In addition to charging the built-in battery via a fuel cell or a combustion engine, a possible charging function from the public power grid can also be added as an option.
