Name Masahiro Yasutake Title of the Research Developing Porous Transport Electrode for Low Iridium Loading and High Current Density Operation of Polymer Electrolyte Membrane Water Electrolysis (PEMWE) Outline of Research Green hydrogen production by water electrolysis is a key technology for realizing a decarbonized society. The issue of high green hydrogen production cost is primarily due to operating expenditure and capital expenditure. PEMWE especially has a clear advantage over other water electrolysis technologies due to its ability to operate at high current density. The overall electrode area could be reduced at high current density operation, leading to an overall reduction in capital expenditure. A significantly high amount of platinum group metal (PGM) catalyst used in the anode due to rate-determining anode reaction is also another issue. The objective of this research is to therefore develop a low PGM loading anode, while realizing high performance and high current density operation for overall reduction of capital expenditure. Currently, we have developed a novel anode, which has the potential to exhibit high catalytic activity and suppress mass transport resistance at high current density operation. Activity Report, etc

Name Hikona Sakai Title of the Research Elucidation of turbulence-driven transport physics in hydrogen isotope plasmas through the development of measurement equipment Outline of Research Through developing a turbulence measurement system, a comprehensive understanding of plasma confinement by focusing on two physical phenomena in hydrogen isotope plasmas is aimed. The first is to clarify the behavior of turbulence and its contribution to transport inside the ITB (internal transport barrier), which has been reported to improve transport through experiments and simulations. Second, the interaction between macroscopic fluctuations and turbulence excited by fast ions simulating α-particles generated in a fusion reactor and their transport changes will be pursued.

Name WEI XUESONG Title of the Research Dramatic improvement of critical current density based on the analogy of boiling and water electrolysis Outline of Research The world’s energy consumption is increasing year by year, and renewable energy power generation has received a great deal of attention in recent years. For the demand of using the excess energy generated by renewable energy more efficiently without wasting, there is a need to develop alkaline water electrolysis, which can transform excess generated electricity into hydrogen, as a large-scale and low-cost electricity storage technology. Therefore, based on the analogy between boiling and water electrolysis, we applied the cooling method by using a honeycomb porous plate, which significantly improved boiling Critical Heat Flux to alkaline water electrolysis and improved the performance of water electrolysis. To clarify the mechanism of water electrolysis improvement from the microscale, we develop a honeycomb porous electrode creation technology with which a honeycomb porous structure can be formed by a self-organization process, then build a theoretical model based on the experimental results.

Name Takahiro Uemura Title of the Research The Determination Mechanism of Fatigue Strength of Bended Pipe for High-Pressure Hydrogen Equipment Outline of Research Hydrogen refueling station equips hundreds of cone-and-thread fittings for connecting pipes, which increases construction cost. In addition, periodic confirmation works to prevent screw loosening also raise the regular maintenance cost. In such a situation, the use of bended pipes is required. Although the domestic regulation limits radius of bended pipe for use in high-pressure gas, its rationale is not established. This study aims to reveal the fatigue strength of bended pipes, which can be affected by various influencing factors, e.g., residual stress, work hardening and thickness change, by means of both experiments and numerical analyses, leading to a reasonable review of the existing regulation.
