Smoltek is awarded a new patent. The first one in a new patent family called Electro Catalyst Support, which is targeted towards the production of green hydrogen. This innovation discloses how our carbon nanofibers can support the iridium catalyst load in a PEM-electrolyzer in a better way. This patent also brings our IP portfolio to comprise 80 granted patents.
The Electro Catalyst Support is the first patent of a new patent family regarding how to use Smoltek’s core technology in electrochemical cells. In this case – how we can use the technology to radically decrease the amount of iridium catalyst load in PEM water electrolyzer cells as well as increase the output per area of the cell.
With this new patent family Smoltek expands its IP portfolio to include the field of green hydrogen production. This is a breakthrough for us as we now can be a key supplier of technical solutions that enable the hydrogen industry to scale up the production of PEM electrolyzers.Fabian Wenger, Head of R&D at Smoltek Hydrogen
The Electro Catalyst Support patent family is covering an electrolyzer and a method for producing a catalyst supported on a nanostructure. The innovation relates to devices used in electrolysis, particularly for the electrolysis of water, a way of producing hydrogen gas without fossil fuels. It provides means of converting excess electrical energy from intermittent energy sources, such as wind and solar power to chemical energy for storage and later use.
The approved claims cover an electrolyzer containing elongated, vertically oriented nanostructures used to create a connection between the catalyst particles on the protected nanostructure and in contact with the membrane providing conducting paths for both ions and electrons. The technology is suitable for nanostructures that are at least partially covered by a protective layer designed to increase resistance to corrosion (i.e. so they are durable for use on the anode side of the PEM electrolyzer).
Smoltek’s patent portfolio now globally comprises 80 granted patents. Read more about our IP and patents.
