Sumidia™ is an nano-polycrystalline diamond that makes a perfect mold-finishing for fuel cell separators. Its extremely high-precision on super hard materials also helps the design flexibility of fuel cell stacks.


Celmet™ is a porous metal that has the highest porosity and best electrical conductivity. It works as a current collector for batteries and fuel cells to achieve efficient gas utilization and simplify inter-connector structures


Gaskets for cells maintain the flows of hydrogen and oxygen inside the fuel cell. Our gaskets have wide temperature range that enables the long-term durability, and their flexibility helps you tailor complex structures in fuel cells
