Latest Patents

Two of Oh’s latest patents address hydrogen management and fuel cell vehicle startup.

“Hydrogen purging device and method for fuel cell system” describes a system that routes hydrogen discharged from a fuel cell stack’s anode to its cathode. The design connects a water trap and hydrogen recirculation blower to the anode outlet, and uses a purging line linking the water trap’s hydrogen outlet to the humidifier inlet. This arrangement supports hydrogen purging during idling or normal driving.

“Device and method for controlling starting fuel cell vehicle” describes a startup process that considers how long the fuel cell has been stopped and its average cell voltage. Depending on those measurements, the system can switch to a catalyst-activating mode, lower the average voltage below a specified threshold, and start the fuel cell by supplying air to its cathode.
