Latest Patents
One of his latest patents is a method of manufacturing a metal column using 3D printing technology. This method includes several steps, such as creasing a 3D-CAD design for printing, printing the metal column, pretreating the inner surface of a channel at low temperature, and coating the inner surface with a stationary phase. This innovation allows the metal column to effectively separate a gas mixture into its components.
Another significant patent is related to the bipolar plate of a polymer electrolyte membrane fuel cell. In this design, a plurality of channel elements have varying widths, which increases the fluid flow velocity from the inlet to the outlet. This design ensures that water generated during condensation can be discharged smoothly. Additionally, the contact angles of the channel elements are optimized to enhance the concentration of the reaction gas on the gas diffusion layer, preventing performance reduction even when gas concentration decreases.
