Latest Patents

One of Yeo's latest patents is a ZnO-based varistor composition. This composition includes zinc oxide (ZnO) as the main component and a calcium (Ca)-containing compound as an accessory component. The varistor composition is notable for its excellent electrostatic discharge (ESD) characteristics and physical properties, such as a nonlinear coefficient and a clamping voltage ratio. Importantly, it does not include BiO, which enhances work safety by avoiding the use of SbO, a compound regulated for environmental purposes. Additionally, this varistor composition reduces manufacturing costs by eliminating Pr-based components that require high-temperature sintering.

Another significant patent by Yeo is related to solid oxide fuel cells and their manufacturing method. This invention involves a solid oxide fuel cell that integrates multiple unit modules. Each module consists of first and second solid electrolyte layers, with fuel electrodes arranged in a strip shape. The design allows for efficient fuel and air paths, optimizing the performance of the fuel cell.
