Stiesdal Hydrogen has developed a novel electrolyser stack aimed at enhancing the production of hydrogen gas.
The patent, filed on August 9, 2024, introduces significant improvements in the design and operation of electrolysers, a critical component for the efficient production of hydrogen.
Features and Improvements
The patented electrolyser stack features multiple bipolar electrically conductive metal separator plates. Each plate sandwiches a membrane and has raised surface portions that create minor gas channels. This design facilitates the transportation of produced gas along the separator plates. The structured area with minor channels is surrounded by both upper and lower major channels, connected via first and second major channels on either side. This innovative configuration ensures effective gas flow and circulation of the electrolyte through the structured areas, enhancing the efficiency of hydrogen production.
Potential Applications
The primary application of this technology is in hydrogen production systems. Given hydrogen’s role as a clean energy carrier, this electrolyser stack can significantly impact industries seeking sustainable energy solutions. Potential use cases include:
1. Renewable energy storage
2. Industrial hydrogen production
3. Fuel cell technology
4. Hydrogen refueling stations
By improving the efficiency of electrolysers, this patent could support the growing demand for hydrogen in various sectors, including transportation, power generation, and industrial processes.
