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.
