The Structural Materials Evaluation Lab studies why structural materials used in aircraft, Shinkansen trains, automobiles, rockets, and similar applications break. The lab combines 3D/4D imaging at the SPring-8 synchrotron radiation facility, computational science from the atomic scale to the macroscale, and the evaluation of strength in a variety of materials. The materials it handles are centered on metals, and also include ceramics, polymers, and composite materials. By revealing how materials actually fail, the lab aims to contribute to the development of new structural materials and to guidelines for appropriate design.

The Fluid Control Lab mainly studies the various phenomena in the internal flow of fluid machinery and its components. Fluid machinery is the general term for machines that exchange energy with a flowing fluid such as water or air. Machines that give energy to a fluid include pumps, fans, and compressors, while machines that receive energy from a fluid include turbines, wind turbines, and water turbines. Through improving the efficiency of these machines, clarifying the related phenomena, and making effective use of low-energy resources such as low-head water, the lab aims to contribute to society.

The Advanced Hydrogen Systems Lab studies hydrogen energy as one means of making effective use of renewable energy toward a decarbonized energy society. The lab covers both hydrogen production by water electrolysis, which links renewable energy and hydrogen, and fuel cells, which convert hydrogen into electricity. In both, the electrode layer where the reactions take place determines performance, so the lab designs these electrode layers starting from the materials. Besides the materials themselves, such as catalysts, porous carbon supports, and proton conductors, the lab also develops methods to evaluate the role of each separately.

The Hydrogen Storage Systems Lab studies what happens to metal components inside equipment that uses hydrogen. When hydrogen enters a material, its strength and ductility can drop. This is called hydrogen embrittlement. Hydrogen embrittlement is an obstacle to designing equipment safely and to reducing costs. The lab studies a wide range of materials, including stainless steels, martensitic steels, and nickel-based superalloys, examining how fatigue cracks grow and measuring fracture toughness in hydrogen gas. The lab has equipment for tensile and fatigue testing in high-pressure hydrogen gas, as well as a torsional fatigue testing machine and a testing machine that can produce a wide range of temperatures, from low to high, in air. The surfaces of fractured specimens are observed with a field emission scanning electron microscope. EBSD is used to examine crystal orientation, and thermal desorption analysis is used to measure the amount of hydrogen released from a material. Students run the equipment and carry out their experiments themselves, and receive support from technical staff for equipment that requires advanced knowledge and skills.

The Fuel Cell Systems Lab studies electrochemical energy conversion devices such as fuel cells and water electrolyzers. These devices are highly efficient regardless of scale, quiet, and reliable, so they are expected to be at the core of the next-generation energy society. To bring them into widespread use, the lab works on reducing costs and improving durability and performance, taking the perspective of system engineers grounded in mechanical engineering.

The Solid Mechanics Lab studies the strength of materials used in machines, with the ultimate goal of making mechanical structures operate safely. The safety of a machine is evaluated with the Stress-Strength Model, which compares the applied force (Stress) with the strength of the material (Strength), but many problems remain unsolved on the strength side. The lab therefore examines strength experimentally and analytically from the viewpoint of micro-scale mechanics, and links the results to computer-based analysis methods. While investigating metal fatigue and the effects of hydrogen, the lab also works on solving failure problems in real mechanical systems such as automobiles.

The Fluid Design Lab studies the optimization, robustness enhancement, and intelligentization of fluid machinery by combining fluid engineering with mathematical and data science. The lab also studies the flow inside turbomachinery using optical imaging-based measurement methods such as pressure-sensitive paint, temperature-sensitive paint, and particle image velocimetry. Graduate students (including international students) and undergraduate thesis students receive research supervision.

The Bio-Thermal Engineering Lab conducts research in bioengineering, thermal engineering, and bio-thermal engineering, which involves both. Bioengineering is a discipline that addresses and solves problems in medicine and biology from an engineering perspective. Even in research related to cells and medicine, the foundation of the lab's thinking lies in mechanical engineering, including thermal engineering, and the lab values a mechanical engineering perspective. The lab is most interested in minimally invasive cancer treatment using electrical effects on cells, the biomechanics of tendon, bone, and cartilage, and the open-source design of biology education materials.

The Thermal Energy Conversion Engineering Lab aims for innovative, effective use of thermal energy and conducts research on boiling, evaporation, multiphase flow, and adsorption. The generation, conversion, and transfer of thermal energy, as well as temperature control, are major issues in energy technology, electronics, production technology for new materials, and the analysis of environmental problems and safety. Because advanced, effective use of energy is essential in addressing global warming, the lab conducts research toward solving these problems. The lab belongs to the Thermal Engineering Division of the Department of Mechanical Engineering, Faculty of Engineering, Graduate School of Kyushu University.

The Hydrogen Production Process Lab (Matsumoto Lab) takes "environmental and energy electrochemistry" as its keyword and studies the development and application of functional materials centered on solid materials that conduct protons. A proton is the positive ion of hydrogen. Solids that conduct protons can be used in many hydrogen energy applications, such as fuel cell power generation and hydrogen production by electrolysis. In steam electrolysis, the lab has succeeded in highly efficient steam electrolysis experiments by improving electrode materials and making the electrolyte thinner. The lab is also developing new ion-conducting solids and exploring new phenomena and underlying science hidden in the behavior of ions inside solids.
