This is the seventh granted patent protecting our innovations in hydrogen solutions and it brings our IP portfolio to a total of 96 granted patents.

This specific innovation protects an electrolyzer anode that combines nanostructures, such as carbon nanofibers, with a comprehensive corrosion protection in the form of platinum. The platinum coating is designed to follow the contours of the nanostructures and thereby utilize the surface area to the maximum. Parts of the surface are also covered with iridium oxide particles that form a coherent catalytic layer, which contributes to both catalytic activity and increased corrosion protection.
