Hydrogen Fuel Cell Technology
Hydrogen fuel cell: a zero-emission electric technology for mobility and stationary applications.
Fuel cells convert hydrogen and oxygen into electrical energy. They are the heart of the technology developed by Symbio. The hydrogen fuel cell is a high-performance zero-emission energy generation solution that can be used for both on-road (such as trucks, light commercial vehicles and passenger cars) and off-road (e.g. construction and handling equipment) mobility applications, as well as for stationary applications (data centers, etc.).
The benefits of fuel cells
- Zero emission of CO2 and NOx during use
- Possibility of storing renewable energies produced by non-controllable sources (wind, solar)
- High energy efficiency
- Technical reliability and durability
- Adaptable to different types of applications
- No noise nuisance

What is a fuel cell stack? How does it work?
A fuel cell stack is the heart of fuel cell system. It gathers numerous individual fuel cells stacked on top of each other. They are composed of the four elements enabling the electrochemical reaction between hydrogen and oxygen; the End plates, Bipolar plates, Gaz Diffusion Layers, Membrane Electrode Assemblies.
It is the fuel cell stack that generates electricity and releases only water vapor and heat, making it a “zero-emission” technology. There are different types of hydrogen fuel cells. We have opted for the PEM fuel cell technology (Proton Exchange Membrane), in which the electrolyte consists of a polymer membrane.
The battery-fuel cell hybridization strategy, for ever more efficient electric vehicles.
Combining the advantages of fuel cells with those of electric batteries in a fuel cell electric vehicle is particularly well-suited to the needs of light commercial vehicle customers looking for long range, fast refuelling and zero emissions, without compromising on payload. This battery/fuel cell hybridization allows the vehicle to use the best energy source for each situation :
- at start-up and low speeds, only the battery is used
- at cruising speed, the energy required by the electric motor
- during acceleration phases, the fuel cell and battery are used to generate the energy required by the motor
- during braking and deceleration phases, the battery is recharged
