Everyone's talking about sustainable energy - we're getting it on track.

We are a company with probably the most experienced employees in our technology field in the world.

The goal is to establish cellcentric as a leading global manufacturer of fuel cells, contributing to climate-neutral and sustainable transportation.

 

The Manufacturing Engineering team is responsible for the planning, commissioning, and acceptance of production equipment across the entire value chain, from catalyst manufacturing to fuel cell system assembly.
