Outline of Final Research Achievements

Fuel cell devices that convert hydrogen into energy are a key technology in building a hydrogen society. In order to create an excellent fuel cell, it is important to design each of the fuel cell components such as electrodes, electrolytes, separators, and catalysts, but it is also extremely important to control the interface of these components. In particular, the interface where all three phases (fuel phase/electrolyte phase/catalyst phase) come into contact is called three-phase interface, which functions as a reaction active site. It is important to expand the three-phase interface in the system for improving power generation efficiency. In this research, we attempted to create a material that contributes to the expansion of the three-phase interface by utilizing the unique three-dimensional gyroid nano-structure.
