Latest Patents
Hee Mang Lee holds a patent for a "Fuel cell system and method of controlling same." This invention proposes a fuel cell system that includes a discharge valve designed to adjust the flow rate between an inlet and an outlet. The system is connected to a water trap linked to the anode of a fuel cell stack, with an external exhaust line at the outlet. The controller in this system derives an error value based on the difference between the condensate water production amount and the discharge amount of the anode when the discharge valve is open. It also corrects the condensate water production amount based on this error value when the valve is closed and opens the discharge valve when the corrected production amount exceeds a predetermined reference value. This innovative approach enhances the management of water in fuel cells, which is crucial for their performance.
