Experience the transformative power of our innovative surface coatings and unlock the full potential of your electrolyzer stacks.
Next step, green hydrogen production...
For years, HEF’s dedicated research teams have been pushing the boundaries in fuel cell’s bipolar plates coating. Acquired knowledge, industrial and research capacities empower us to address the challenges and request rising from the electrolysis world. PVD solutions in PEM electrolysis are attracting growing interest from manufacturers.
HEF’s expertise on PVD/PECVD is key to optimize Separator/Bipolar plates and PTLs contact performances. Market leaders identified HEF as the right partner to support both industrialization of current solutions and collaboration for next generations of electrolyzer’s stacks.
The group’s others area of expertise in surface functionalization allow to tackle materials challenges of all electrolysers technologies. We think outside the box, pushing the boundaries to find unique and effective solutions.
How does PEM electrolysis work?
In the PEM water electrolysis process, water undergoes an electrochemical splitting into hydrogen and oxygen. This process involves the initial decomposition of water molecules at the anode side, resulting in the generation of oxygen (O2), protons (H+), and electrons (e−).
The produced oxygen is expelled from the anodic surface, while the remaining protons traverse the proton-conducting membrane towards the cathode side. Simultaneously, the electrons travel through the external circuit to reach the cathode side. Finally, at the cathode side, the protons and electrons reunite, leading to the production of H2 gas.
Materials for Separator/Bipolar Plates and PTLs:
For electrolyzers to be deployed worldwide, bringing down the cost is necessary.
HEF’s promise is to propose coatings solutions that guarantees required performances of the components for a reduced loading of precious metals. Our researcher DNA drives us to work on creating the sustainable materials of tomorrow that will unlock the full green potential of PEM electrolyzers.
