Product Information
GDBLs means the carbon paper made from carbon fiber by the wet-laid process. The GDBLs in the polymer electrolyte fuel cell must have the characteristics to the uniform thickness, the enhanced mass transfer and the low electrical resistivity. We have achieved the favorable GDL’s structure by controlling of GDBLs composition. Our concerns are focused on homogeneous properties such as thickness, porosity, flatness and the improving the MEA performance. We can prepared the various thickness of carbon paper, the range from 220μm to 400μm. And by customer’s needs we can supply the controlling porosity and density of carbon paper.

- Company introduction
-
In connection with GDL, we are constructing an evaluation system in relation to the Line capability of manufacturing the Roll firsthand where all processes are involved in the stage of spraying the carbon veil, GDBL, and micro-porous layer. We are committed to becoming the leader in supplying a variety of Roll form products.
With regard to polyelectrolyte type fuel cell, performance of MEA is very dependent on characteristics of the GDL, influenced especially by structure and composition of the micro-porous layer. JNTG has many years of experience in designing micro-porous layers to improve the MEA performance in various evaluation conditions. Also, we are conducting a research based on the relationship between micro-porous layer structure and the catalyst layer to optimize the MEA structure. We have developed the micro-porous layer having a dual structure in the GDBL to enhance transference of fuel and by-product matters in addition to the technology for enhancing the MEA performance in low humidity conditions
Carbon Fiber nonwoven veil is an essential product used in GDL of the hydrogen fuel cell and carbon paper which is used for electrochemical reaction. JNTG has the research infrastructure and production line that can continuously supply products to various sectors requiring durability and electro-conductivity, as well as Polymer Electrolyte Membrane Fuel Cell (PEMFC) and Direct Methanol Fuel Cell (DMFC) fields.
