Yokey provides sealing solutions for all PEMFC and DMFC fuel cell applications: for automotive drive train or auxiliary power unit, stationary or combined heat and power application, stacks for off-grid/grid connected, and leisure. Being a leading worldwide sealing company we offer technologically perfect and affordable solutions for your sealing problems.
Our particular seal contribution to the fuel cell industry is to provide a best design with our fuel cell qualified materials that we manufacture for any development stage from small prototype volume to high volume production. Yokey meets these challenges with a variety of sealing solutions. Our comprehensive sealing portfolio includes loose gaskets (supported or unsupported) and integrated designs onto metal or graphite bipolar plates and softgoods such as GDL, MEA and MEA frame material.
The primary sealing functions are to prevent leakage of coolant and reactant gases and to compensate manufacturing tolerances with minimum line forces. Other important product features include ease of handling, assembly robustness, and durability.
