Hydrogen fuel cell expertise

Hydrogen is playing a key role in the energy transition by helping to reduce greenhouse gas emissions and offsetting the progressive depletion of fossil fuels. Axane has made hydrogen energy its core business by developing autonomous hydrogen-powered fuel cell systems. Increasingly reliable and efficient, they effectively meet the expectations of today's market.

A 100%-owned subsidiary of Air Liquide, Axane has produced and marketed hundreds of innovative fuel cell systems with numerous applications over the last 15 years.

Thanks to its expertise in fuel cells and Air Liquide's expertise in the hydrogen sector, Axane has a unique perspective that it can put to work on coherent projects.

Fuel cell systems are developed in project mode, from design to production down to operation and maintenance. The team works in synergy with Air Liquide’s other entities on issues surrounding hydrogen storage and logistics (solid, liquid, or gaseous), and energy hybridization. Fuel cells have a variety of cutting edge applications, from cinema and telecommunications, to logistics, aeronautics, and space exploration.

We are organized by business line and into project teams that are in constant collaboration with the industrialization and production teams.

We strive to develop highly reliable, efficient and durable technologies that can withstand the most testing climates. We have resolved most of the technological challenges that fuel cell manufacturers face, like start/stop issues. Our technical solutions and our systems allow an electrode lifespan in the field of more than 15,000 hours without maintenance and with no impact on the number of starts/stops. These devices are particularly well suited to mobile and stationary applications with high levels of use. Moreover, the choice of a liquid cooling system allows the heat produced by the reaction to be re-used, thereby also making them suitable for so-called cogeneration applications.

And with Air Liquide, we are capable of organizing the hydrogen supply solutions that best meet our customers' needs.


How do fuel cells work? 

Fuel cells use the opposite process to the electrolysis of water. By combining its hydrogen fuel with oxygen from the air, it generates electricity and heat, with water as the only by-product. This is a non-polluting electro-chemical reaction.

When the hydrogen molecules injected in the fuel cell reach the electrode (the anode), its protons and electrons are separated. The protons cross the polymer membrane while the electrons head for the second electrode along the external circuit, thereby creating an electrical current. This membrane is called the PEM (Proton Exchange Membrane).

The oxygen in the air that arrives in the fuel cell at the second electrode (the cathode) is separated into two oxygen atoms that combine with hydrogen protons, turning into water molecules, which is the fuel cell's by-product.

fuel cell systems used around the world


hours of continuous autonomous use

between -20°C and 55°C

temperature range for use

A clean electricity solution for sites that are not connected to the grid.

Fuel cells can supply a small electrical installation (telecommunications site, isolated home, road safety system, etc.) without the need for traditional solutions such as thermal engine power generators, meaning there is no noise, no moving parts, no pollution, no wear and tear, with a continuous power supply that other types of renewable energy cannot guarantee.

This power supply sets itself apart from rival systems with:

  • The fuel cell's superior life span (> 15,000 h)
  • The system's reduced fuel consumption (0.76 Nm3 / kWh)
  • The option of recovering heat generated to heat the installation supplied
  • Tolerance of extreme temperatures (-20/+55°C)
  • A high level of reliability (availability > 99.5%)

The most demanding customers overwhelmingly choose this solution (telecoms operators, railway network operators, air traffic controllers, highway management, etc.).

Why choose us?

Thanks to 15 years' experience and our collaboration with Air Liquide, Axane has great fuel cell expertise: from design, to industrialization, production and installation. Axane's team continues to innovate based on learnings from past experiences, to develop ever more efficient systems. Its trial center enables Axane to test and improve its technologies.
