Gaskets for the X-Cell

There are two variations of the X-Cell, General Electrolyzer – that is with flat current collectors and with current collectors incorporating af Flow-Field. In general the Flat Current collectors are for use with thick (>1 mm), whereas the Flow-Field configuration is for used with thinner electrodes (<1 mm). However, it may depend on your specific application and materials as well. 

For the X-Cell with flat current collectors, you need both cover gaskets and flow-field gaskets, whereas if you are using current collectors with a flow-field, you should only use cover gasket.

Gaskets for a configuration of the X-Cell using current collectors with a flow-field.

Configuration of the X-Cell using current collectors with a flow-field.

This configuration is intended for thin electrodes (<0.5-1.0 mm). I.e. the interdigitated flow minimises pressure loss for very thin electrodes. For this configuration only cover gaskets are needed (and potentially porous separator gaskets):

The final compressed electrode thickness is the sum of the thicknesses of both the Cover/Spacer gaskets, here several gaskets (and materials) and thicknesses can be combined. In our gaskets products we offer packs of different gasket thicknesses, and we recommend these as these will allow you to test virtually any electrode thickness and compression.

Configuration of the X-Cell using flat current collectors.

The configuration is intended for thick electrodes (> 0.5-1.0 mm). I.e. flow rate can become too low with decreasing electrode thickness because the hydraulic resistance increases. For this configuration both cover gaskets and flow field gaskets must be ordered:

To minimize the pressure loss inside the cell it is recommended to use as-thick-as-possible Flow field gaskets and use Cover/Spacer gaskets to adjust the final thickness/compression of the electrode. The final compressed electrode thickness is the sum of the thicknesses of both the Flow field gaskets and Cover/Spacer gaskets, here several gaskets (and materials) and thicknesses can be combined. In our gaskets products we offer packs of different gasket thicknesses, and we recommend these as these will allow you to test virtually any electrode thickness and compression.

Porous separator gaskets

If you are using a porous membrane/separator, you also need a gasket around the separator to avoid any leackages. The gaskets here fits a separator with a size of 6×6 cm independent of the active area of the electrodes. The gaskets come in different thicknesses and can be combined to obtain the thickness of the separator. We offer a package that allows you to finely adjust the thickness to your needs. 

SINGLE GASKETS & PACKS OF GASKETS:

Gasket can be ordered individually, however, we also offer packs of Spacer/Cover gaskets with a volume discount. These pack includes gaskets with thicknesses that will allow testing and compression of almost any electrodes thicknesses. Typically the PTFE Thin Pack will be combined with one the PTFE, VITON or EPDM Thick Packs.

PTFE Thin Pack includes sets (one pair) of

• 2 sets – 0.05mm PTFE
• 2 sets – 0.1 mm PTFE
• 2 set – 0.25 mm PTFE
• 1 set – 0.5 mm PTFE
