Water Electrolysis Cells and Hydrogen Storage Materials Lab
Machine-translated · View original
A lab that explores water electrolysis, hydrogen storage, and fuel cells from the standpoint of materials.
AboutAbout the lab
Combining renewable energy and hydrogen energy.
The Advanced Hydrogen Systems Lab aims to combine renewable energy and hydrogen energy, and studies the whole chain from hydrogen production by water electrolysis to hydrogen storage and power generation in fuel cells.
Its main subjects are polymer electrolyte fuel cells (PEFCs) for automobiles, polymer electrolyte water electrolysis cells, and hydrogen storage using metal hydrides.
Focusing on electrocatalysts, which determine fuel cell performance, the lab covers everything from materials design at the nanometer scale to the fabrication and evaluation of devices.
Applicants from a variety of backgrounds, including mechanical engineering, electrochemistry, materials engineering, and chemistry, are welcome.
Key terms
- Electrocatalyst
- The part that determines fuel cell performance. It is made of platinum nanoparticles placed on spherical carbon.
- Polymer electrolyte fuel cell (PEFC)
- The type of fuel cell this lab mainly studies for use in automobiles.
- Porous carbon
- A carbon material with nanometer-sized pores.
ResearchResearch themes
The lab aims for the stable use of renewable energy and the full-scale spread of hydrogen energy. Centering on fuel cell electrocatalysts, it also studies catalysts for water electrolysis cells and hydrogen storage materials.
*Illustrative imageNanochannel carbon electrocatalysts
By introducing platinum nanoparticles into the pores of porous carbon with nanometer-sized pores and suppressing aggregation of the particles, the lab aims to improve the performance and durability of electrocatalysts.
*Illustrative imageHigh-temperature operation of fuel cells
To raise the efficiency of fuel cells, the lab is examining operation at high temperatures of about 100°C to 120°C. Higher temperatures also accelerate catalyst degradation, so the lab operates cells at high temperatures to identify problems and feeds the results back into materials design.
*Illustrative imageWater electrolysis catalysts tolerant of fluctuations
The lab designs anode catalysts for water electrolysis that can withstand the voltage fluctuations of renewable energy. Research on catalysts for water electrolysis cells is carried out in collaboration with Professor Ito of Kyushu University.
*Illustrative imageHydrogen storage materials
The lab also works on hydrogen storage using metal hydrides (MH), jointly with Professor Akiba of Kyushu University.
