Tohoku University Technology: Method for producing Proton-containing oxides : T21-224
To enrich the variety of ceramic materials developed that contain protons.
Research and development of high-proton-conducting oxides, which are stable at intermediate temperatures around 300 ~ 600°C, have been carried out for practical applications in electrochemical devices such as fuel cells. However, since most of the existing materials are synthesized through high-temperature sintering, they are limited to perovskite-type or related crystal systems or specific material systems, and the degree of freedom of crystal structure and composition is limited, which limits the development of practical materials. The present invention relates to a manufacturing technique for obtaining a proton-containing oxide by introducing a proton into an oxide by reacting a basic oxide with a carboxylic acid melt. According to this method, it is possible to introduce a proton into various ceramics, which are conventionally difficult to examine, and the range of material selection can be expanded. The present invention, which does not select the shape of the raw material, is expected to be applicable to components such as electrochemical devices, and contributes to the practical application of proton-conducting oxides.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of April 1, 2026): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University - Asahikawa Medical University
