Latest Patents

One of Kyoung Ran Han's latest patents is titled "Methods of producing anodes for solid oxide fuel cells." This patent discloses methods for producing Ni/YSZ porous anode bodies. The innovative approach involves using a small amount of a nickel compound or salt as a pore former. Upon heating in air, the nickel compound decomposes into nickel oxide, releasing gases that result in volume shrinkage. This method allows for the economical production of Ni/YSZ porous bodies with a uniform pore size.

Another notable patent is for a "Cement-free high strength unshaped refractory." This invention includes barium aluminate and a dispersant added to a refractory material containing AlO and SiC, along with an alumina sol binder. This combination significantly improves the handling strength of the unshaped refractory, making it suitable for lining that contacts slag in a blast furnace or a gasifier.
