R&D Results
Finding our place in the market for a hydrogen economy and securing future growth through sustained technological development
Since 2006, JNTG had accumulated technological expertise through the course of developing electrodes, MEAs, and
DMFC. Leveraging this expertise, from 2008 to 2013, JNTG set out to fully localize the production of GDLs in Korea
in partnership with the Hyundai Motor Company as part of phases 1 and 2 of the initiative by the Ministry of
Knowledge Economy to localize hydroelectric vehicle GDLs.
In 2011, JNTG became the first company in Korea to develop a rroll-type carbon paper. Then in 2012, it successfully
developed the first roll-type GDL. Starting in 2013, JNTG worked on building a mass-production system, which
resulted in GDL production line No. 1 (for pilot production) and No. 2 (for mass production). With these, JNTG can
supply GDLs for about 10,000 hydroelectric vehicles. As domestic and international demand is growing for
hydroelectric cars, our plan is to progressively add production lines 3~5 and gain the capacity to produce GDLs for
100,000 vehicles.
JNTG is continuing to invest steadily in our R&D to bring our technology closer to perfection. Currently, we are
working to develop a technology that can allow us to make thinner GDLs and upgrade the durability of existing ones.
We are also developing carbon paper products that can be used in the fuel cells of power generation systems and
electrolyzers.
