Hydrogen Storage alloys and hydrogen storage cylinder stores hydrogen as a key component of submarine fuel cells and hydrogen can also be released under certain temperature conditions and harsh conditions if required. Hydrogen produced when it is combined with oxygen produces electrical energy.

 Hydrogen storage alloys and hydrogen storage cylinders that were imported have been successfully localized by Wonil T&I in cooperation with Agency for Defense Development and the defense industry company. In addition, we fabricated and delivered such products with high performance and high efficiency in 2017 through technological development, which are in compliance with the Client's requirements and are superior to the performance of the existing products.
