elementarhy

elementarhy GmbH was founded in 2024 in Hamburg, Germany. The company began by manufacturing membrane electrode assemblies with ultra-low catalyst loading for PEM water electrolysis. Since then, it has grown into a supplier of materials, hardware and services for small-scale electrolysis research and development and large-scale deployment. elementarhy offers:

• Catalyst-coated components, i.e. 5-layer-MEAs (PTL-catalyst-membrane-catalyst-GDL) with ultra-low catalyst loading. Catalyst-coated electrodes made by PVD deposition of iridium oxide and platinum onto all common substrates used in water electrolysis. Porous transport layers (PTLs) with PVD-based platinum coating for corrosion protection.
• Electrochemical hardware and software, i.e. controllers and measurement units for single electrolysis cells. Every measurement ends up in one place: the elementarhyHUB. Our devices stream data into this web interface and database, and a built-in segment library lets you define and reuse test protocols. Everything runs locally, and your data never has to leave the lab. Furthermore, elementarhy is a partner of Nordic Electrochemistry. It develops Nordic Electrochemistry’s products further and is a distribution partner of high-quality potentiostats and electronics.
• Testing services for external evaluation of materials and components As such, elementarhy provides high-quality equipment along the whole supply chain of electrochemical research.
