Engineering design and development

轴上designs and manufactures fuel cells, stacks, and systems based on PEM technology (proton exchange membrane), with power ranging up to hundreds of kilowatts.

This know-how extends to elements specific to stacks (fluid circulation, sealing...), and to complete systems (auxiliary components, operating conditions, and safety...). Our customers are supported by our experts at all stages of their project, from analysis of needs, and co-writing specifications, to product development, and the eventual transfer of skills required for production start-up.

轴上's engineering services for fuel cell design

Our engineers are experts in the design of stacks and fuel cell systems for a variety of application areas. This unique know-how attracts companies including one of the world leaders in fuel cells for forklift trucks to partner with our teams in developing a new range of fuel cells for the European market.

Stages of project development in partnership

Co-construction of technical specifications

Our engineers analyse your needs, a fundamental step for your project. Knowing how to identify the fundamental characteristics is crucial to guarantee the efficiency and profitability of your product. What are your priorities? Fuel Cell lifetime, compactness, performance, reliability, production cost?

At each stage our design office provides the advice you need to make the best decisions, which we then incorporate together in your specifications.

定制产品设计(堆栈,系统,长凳)

Throughout this process, our experts subject your products to several tests that evaluate their performance, reliability and suitability in accordance with your specifications.

Our project management method – Cycle V – results in a high-performance product based on quality design.

Preliminary design

To define the system architecture, we study the structure of the fuel cell system, draw up the functional architecture diagrams and measure potential risks.

Detailed design

At this stage, our experts design the detailed drawings of the stacks and fuel cell systems. This work includes the specification of all materials and components of the assembly, as well as the tools and software required for its implementation.

We validate the technical hypotheses and perform the necessary calculations for the brief, with certain elements prototyped. For example, sub-component testing allows us to validate hypotheses and identify potential problems, with the aim of reducing the level of risk and uncertainty. In this way, our experts can ensure that production complies with specifications and decide to proceed with the assembly of your system or stack.

Prototyping

Prototyping is to validate whether your fuel cell system confirms with specifications such as:

  • Electrical performance
  • Mechanical characteristics
  • Reliability
  • Lifetime
  • Manufacturing cost.

The prototype is subjected to multiple tests at our dedicated site in Sassenage. Our teams can then manufacture pre-series for testing of your products in real-life situations.

Transfer of skills

我们的合作可以随着技能转移给您的团队,让您在完全自治中操作氢燃料电池系统的制造。

Fuel cell: how does it work?

dp_hydrogene_octobre_2018-5.jpg

For 1 to 120 kW cells, Axane uses PEM (proton exchange membrane) technology. Through an electrochemical reaction, the cell produces electricity and heat while only emitting water.

The fuel cell consists of several cells, each containing a membrane electrode assembly (MEA), which is the active heart of electricity generation. The MEA consists of two electrodes, the anode (negative) and cathode (positive), on either side of the PEM membrane.

At the anode, H2hydrogen molecules are transformed into H+ ions (protons) and electrons. The H+ions are directed to the cathode through the PEM membrane. At the cathode, they react with oxygen and electrons to form water. The production of electrons and their consumption generate the expected electrical current and power.

The electrochemical reactions at the electrodes are:

at the anode 2 H2→ 4 H++ 4 e-
at the cathode O2+ 4 H++ 4 e-→ 2 H2O

The resulting overall electrochemical reaction is:

O2+ 2 H2→ 2 H2O
