Latest Patents

One of Aoki's latest patents is a hydrogen separation membrane. This invention pertains to a polycrystalline membrane containing metal nitride particles represented by the general formula MN. The membrane features a crystallite size determined by transmission electron microscopy of 10 nm or less. At least some of the crystallites have a rock salt-type structure, exhibiting (111) orientation while substantially not exhibiting (100) orientation. The invention also includes a method for manufacturing this polycrystalline membrane through sputtering on a substrate at temperatures below 200°C. This hydrogen-permeable TiN microparticle membrane demonstrates higher mixed hydride ion (H)-electron conduction.

Another significant patent by Aoki is related to a proton ceramic fuel cell (PCFC). This invention features a hydrogen-permeable film as an anode, with an electrolyte material composed of BaZrCeYO. An electron-conducting oxide thin film, with a thickness of 1-100 nm, is present between the cathode and the electrolyte. The method for producing this PCFC involves forming a thin film between the cathode and the electrolyte, which enhances the output of the fuel cell, exceeding a benchmark of 0.5 W cm at 500°C.
