Gas Diffusion Layers(GDL)

GDLs based on non-woven substrate are designed to enhance mass transfer of the fuel and byproduct through controlling pore distribution in the micro-porous layer and the property of GDBL. And GDLs have been designed to decrease the interfacial resistance between the catalyst layer and bipolar plates. Our concerns are focused on the homogeneous properties of GDL such as thickness, pore distribution, porosity, flatness and so on.

Manufacture of GDL

GDLs of the fuel cell are made up the GDBL and micro porous layer(MPL) that is consisted by carbon black and binder. GDLs engender hydrophobic property through the hydrophobic polymer treatment of the GDBL, we have controlled the PTFE content 5 to 40wt% in GDBL.

Specification

We can supply the controlled MPL structure of GDL by customer…s need and condition.

• JNT-20 based GDL have thin thickness and good MEA performances, specially DMFC system.
• JNT-30 based GDL have been designed for the stationary FC system and show good MEA performance at high humidified fuel condition.
• JNT-40 based GDL have about 400., the low compressibility and bending stiffness. And JNT-40 based GDL offer high density and the improved mechanical properties. MEA performance with JNT-40 based GDL show good at low humidified fuel condition because of the well-designed water management structure.
