ELAT Hydrophilic Plain Carbon Cloth gas diffusion layers are excellent for flow batteries. The excellent tensile and interlaminar shear strengths prevents fabric wrinkling. Hydrophilic ELAT is designed specifically for liquid type electrochemical reactors. The thickness of this GDL is 406 um.

ELAT - Hydrophilic Plain Cloth: Properties and Advantages:
Liquid reactant consuming electrochemical devices require the liquid medium to fully access the electrocatalyst layers and hence, wettability of the gas diffusion layer becomes the prime importance for excellent electrochemical performance.  ELAT - Hydrophilic Plain Cloth is manufactured with our own proprietary treatment in order to generate the hydrophilic nature into it.  The plain cloth is solely comprised of long carbon fibers and does not have the microporous layer (MPL).  As soon as the liquid reactant enters the electrochemical device, it immediately reaches the surface of the anode or cathode electrocatalyst and starts reacting.  This product has good compressibility in order to provide compliance for thickness variation in other components, excellent electrical conductivity and mechanical resilience, and does not have any PTFE treatment (also known as Teflonization).  These features make ELAT – Hydrophilic Plain Cloth ideally suitable for all flow batteries, direct methanol fuel cells, electrolyzers, batteries, and various other electrochemical devices.

In addition to usage of this hydrophilic carbon cloth in electrochemcial devices as the electrode itself (either with a catalyst or no catalyst), surface hydrophilicity of this GDL also make it ideal for deposition of various materials via electroless or electrolytic methods for studying of catalytic materials under ex-situ conditions.
