A materials strength lab that studies the strength of metals used in hydrogen environments.

The lab studies how metallic materials exposed to hydrogen gas are changed by the effects of hydrogen. Hydrogen embrittlement, in which hydrogen enters the interior of a material and reduces its strength and ductility, is an obstacle to the safe design and cost reduction of equipment that uses hydrogen. The lab works on elucidating the mechanisms of hydrogen embrittlement, establishing criteria for selecting metallic materials used in hydrogen gas, and establishing strength design methods for hydrogen equipment. On the lab's website, it is introduced under the name "Hydrogen Storage Systems Lab (Matsunaga Lab)".

The lab uses electron microscopy to study fuel cell materials at the atomic level.

Professor Junko Matsuda is a faculty member of the Hydrogen Utilization Process Lab and is involved in research that examines fuel cell materials with electron microscopes. The Hydrogen Utilization Process Lab aims to realize a hydrogen energy society centered on fuel cells, which convert energy to generate electricity and heat without combustion. Observation with atomic-resolution high-resolution electron microscopy has become an essential technique in research on a wide variety of fuel cell materials. This site belongs to the lab headed by Distinguished Professor Kazunari Sasaki.

The lab studies gas diffusion layers that improve the power generation performance of fuel cells.

The Kitahara Team of the Fuel Cell System Lab researches gas diffusion layers to improve the performance of fuel cells. The team makes gas diffusion layers coated with a microporous layer (MPL), varying the composition, pore size, porosity, and thickness, and examines the effects on water repellency and on gas and water permeability. The goal is to establish design guidelines for high-performance gas diffusion layers that resist drying out even under low-humidity, unhumidified conditions. This site introduces the research of the Ito Team, the Kitahara Team, and the Nakajima Team together.

A hydrogen energy lab that makes the inside of fuel cells visible.

Associate Professor Yuya Tachikawa is developing high-temperature fuel cells and methods to analyze them, with the theme of achieving high-efficiency power generation aimed at reducing CO2. In the Hydrogen Utilization Process Lab, Associate Professor Tachikawa and colleagues are researching how to visualize, through numerical analysis and experiments, the temperature changes, chemical reactions, and thermal stress distribution that occur inside fuel cells. Based on a vision of a future hydrogen-based society, the lab also examines the effects of producing hydrogen with renewable energy and develops technologies toward CO2-free energy. This lab site belongs to the Hydrogen Utilization Process Lab headed by Professor Kazunari Sasaki, and Associate Professor Tachikawa is listed as a member.

The lab designs the electrodes and cell structures of fuel cells and water electrolyzers.

The Electrode Materials and Porous Diffusion Layers Lab studies fuel cell and water electrolysis technologies, which handle energy conversion for renewable energy and hydrogen. In water electrolysis, which splits water with electricity to produce hydrogen, the lab works on designing cell structures that achieve both high efficiency and high durability while reducing the amount of precious metals used. For solid oxide cells, which operate at high temperatures, the lab investigates the relationship between electrode degradation and the acid-base properties of the electrode surface through international collaborative research. The lab's website presents it within the research of the Hydrogen Utilization Process Lab.
