Smoltek has been granted three new patents – all in the field of reducing contact resistance in electrolyzer and fuel cells




Smoltek has been granted three new patents – all in the field of reducing contact resistance in electrolyzer and fuel cells.


Smoltek Nanotech Holding AB (“Smoltek”) announces that the company has been awarded three new patents. The patents are divided into three new and separate patent families, all related to how Smoltek’s technology can reduce contact resistance between different layers in electrochemical cells, mainly for use in electrolyzers and fuel cells. These new patents also bring the IP portfolio to comprise 87 granted patents.


Smoltek has been awarded three new patents. Each one of these relates to a new patent family, all of them describing how we can use Smoltek’s core technology for reducing contact resistance in electrochemical cells.


Electrochemical cells are found in widespread applications in modern energy systems, such as batteries, fuel cells and electrolyzers. However, existing chemical cells possess high contact resistance between different components of the cell which leads to lower efficiency. This problem may even be worsened by the formation of non-conducting surface layers on some components due to the harsh environment of the cell.


Fabian Wenger, Head of R&D at Smoltek Hydrogen, said:


With these three new patent families, we are really strengthening the scope our IP portfolio within the field of increasing the efficiency in electrochemical cells, both for electrolyzers and fuel cells.


Ellinor Ehrnberg, President of Smoltek Hydrogen, said:


It is very valuable for us to have a platform of patents that have wider areas of use than in just PEM electrolyzers.


“especially when we are talking to different companies in the hydrogen industry, who often work both with fuel cells and several different types of electrolyzers. This opens new opportunities for our business”, 


Innovation description of the new patent families


Contact Resistance patent family: The Innovation improve a separator plate arrangement for an electrochemical cell by comprising a nanostructure which offers lowered contact resistance between the separator element and the diffusion layer.


Nano Velcro patent family: The Innovation improves the interlayer connections in electrochemical cells by using elongated nanostructures that are mechanically entangled between the layers.


Vertical Graphene patent family: The Innovation offer lowered contact resistance between separator elements and adjacent components in electrochemical cells and increase resistance to corrosion.
