Hydrogen-based propulsion solutions: a definition

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

  • Power generation from hydrogen using fuel cells
  • Power generation from hydrogen via combustion engine
  • 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. Here, one uses the higher efficiency of the electric powertrain and the coverage of the peak power by a (small) battery, in order to then be able to design the combustion engine or fuel cell to be smaller in power.

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

Adaptation to your specific application by optimizing battery capacity and fuel cell power


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.
