Sealing technology: There are several new R&D products that can be used as accessories for hydrogen fuel cells, but large-scale supply has not yet been achieved.

Sealing technology on the interactive platform indicates that the company has newly developed products, such as the helium compressor for hydrogen liquefaction with ultra-low temperature refrigeration, seals for hydrogen station diaphragm compressors, diaphragm pieces, and high-speed air-floating bearings for hydrogen fuel cell air pumps, which can be used as accessories for hydrogen fuel cells. There is a small amount available for customer trials, but mass production has not yet been achieved, and there is still significant uncertainty for large-scale commercial applications.
