Electrolyzers, Fuel Cells & Dexmet Expanded Materials

Dexmet has been providing materials into the fuel cell and electrolyzer industry for over 50 years.  Over this time, Dexmet has redefined how expanded materials can be incorporated into Electrolyzers, Proton Exchange Membrane (PEM) and Solid Oxide (SOFC) Fuel Cells.  The efficiency advantages of using an expanded product when working with expensive materials such as Niobium, Zirconium, Silver, Titanium and Nickel make it more economical solution over similar perforated or chemically etched products. The unique simultaneous slit and stretch process can yield up to 90% more finish product output than raw material input.  So when trying to reduce the overall cost of a fuel cell stack, expanded materials are a better overall solution.

Applications Within A Electrolyzer or Fuel Cell Stack

Fuel Cell stacks are made up of several layers of material. The versatility of MicroGrid and PolyGrid materials can be utilized in many of these layers to increase performance and reduce cost

Excellent as a Catalyst Substrate

The open area design allows for more surface area to deposit the catalyst. The open area design allows for better flow through the catalyst improving ion separation

Gas Diffusion Electrodes, Flow Field Structures and Current Collector Screens

The 3D geometry allows for more consistent diffusion over the catalyst increasing efficiency.

Membrane Support Grids

As stack pressures increase the need for membrane support materials becomes essential to reduce the amount of flex the membrane is subjected to during operation. MicroGrid® and PolyGrid® materials are perfect support materials for reducing the amount of flex without affecting flow through the system

New Expanded Corrugated Products

Dexmet has configured a product that answers the need of Fuel Cell designers trying to increase the efficiency of the anode and reduce stack cost through multi-functional products. Dexmet's new expanded corrugated product, when used as the anode substrate, increases the amount of surface area allowing for catalyst material to be applied. The new product can also enhance the flow through the substrate for better ion separation.

Variability in the manufacturing process allows the Customer to specify the Amplitude and Frequency, as well as the Open Area of the material, to optimize surface area and flow for the application.  In addition, this product can also be utilized to create the Hydrogen and Oxidant Flow Field layers within the stack
