Title: Innovator Kyoung-Hwang Lee: Pioneering Fuel Cell Technology
Introduction
Kyoung-Hwang Lee, an accomplished inventor based in Gwangju, South Korea, holds three patents in the field of fuel cell technology. His innovative work has significantly contributed to advancements in fuel cell efficiency and performance. Operating under Doosan Corporation, Lee has demonstrated a commitment to enhancing sustainable energy solutions through his inventions.
Latest Patents
One of his latest patents involves a groundbreaking fuel cell separator and stack along with a method for reactant gas control. This inventive approach enables reactant gas to be supplied to the passages of the fuel cell separator even during low-load operation, reducing the length of the passage by 50% compared to previous designs with a single reactant gas passage. This improvement allows for effective gas supply without pressure loss.
In high-load conditions, the reactant gas is strategically introduced into separate passages, optimizing the usage across the electrode area. This dual-pass system increases the flow rate of reactant gas—by two times—that efficiently discharges moisture and prevents flooding, a common issue in high-load operations. Lee's method ensures that the flow and operating conditions maintain stability without causing pressure loss or reducing the utilization rate.
