What we do

What we do

With the combined forces of the Daimler Truck AG and the Volvo Group, we bring together 30 years’ worth of extensive experience in developing safe and efficient world-class fuel cell systems. By using hydrogen in our fuel cells, we create energy without emitting anything but pure water.

As the pioneer in developing, manufacturing and repairing hydrogen fuel cell systems, our aggregates are applicable for any use case. They can be flexibly adapted to various use cases such as a clean powertrain in trucks and other commercial vehicles or as an emergency power supply of critical facilities in data centers.

Today, more than 300 highly specialized colleagues work on the success of fuel cell systems in inter-disciplinary teams at the locations in Nabern, Untertürkheim (Germany) and Burnaby (Canada) together with our participating technology and cooperation partners. Around 700 individual patents have been issued, underlining the leading role played by the company when it comes to technological development. The ambition is to make cellcentric a leading global manufacturer of fuel cells, and thus help the world take a major step towards climate-neutral and sustainable transportation by 2050.

How a Fuel Cell System Works

In a fuel cell, the continuously supplied hydrogen reacts with the oxidant oxygen. This produces water, electricity and heat. This electrochemical reaction is also called “cold combustion” and is particularly efficient.

How a Fuel Cell Works

The systems developed by cellcentric Fuel Cell are based on PEM (Proton Exchange Membrane) fuel cells, which are operated using hydrogen and oxygen from the air.

  • Hydrogen is supplied from the anode side, atmospheric oxygen from the cathode side.
  • The hydrogen molecule H2 is split into two protons and two electrons via a platinum catalyst.
  • Electrons flow as electrical current through various electrical consumers, while the protons diffuse through the membrane.
  • The potential difference between the anode and cathode generate electrical voltage. By stacking several cells, the voltage of several cells can be combined.
  • The oxygen molecule O2 is split catalytically at the cathode into two oxygen ions through the acceptance of four electrons. Every oxygen ion connects with two protons to form a water molecule.
  • The water is carried out of the fuel cell by the airflow
