Protonics is based on integrated sciences and technology for utilizing hydrogen atoms and molecule, hydrogen radical, proton (hydron), and hydride. It can contribute to the future hydrogen society through fuel cells, which are one of the ideal power sources for the next generations.
Since we found enhancement phenomena of the proton transport in the confined polymer thin films (so-called Nanoprotonics) on 2008, our group develops highly proton –conductive polymers for the energy devices by our own concept.
Our interest is to investigate the relation between the polymer organized structures and high proton transport property. A well known Nafion for a high proton conductive polymer is a less ordered structure, however, our group has developed some highly proton-conductive organized polymers with both the confined space and organized structure.
With many collaboration to international universities, institutes and companies, we are challenging to develop future technologies for not only fuel cells but also related energy sectors to create science and technology of Protonics.
