New energy technologies and manufacturing technologies are essential toward 80% reduction of CO2 emission of the IPCC 2ÅãC scenario until 2050, because itÅfs difficult to solve imbalance between power supply of solar and wind and electricity demand by present technologies.
Hydrogen can be synthesized from water and electric power, and hydrogen related technologies realizes large amount of energy storage and transportation and new industrial technologies. Regionally produced and consumed renewable energy is important, but overseas renewable energies are also essential to get absolute amount to maintain Japanese industrial sector.
Electrochemistry is direct energy conversion process between electricity and chemical energy, and water electrolysis and fuel cell are key technologies which are hydrogen production from water and electricity, and power generation from hydrogen and air(O2). These technologies can apply to new manufacturing processes of hydrogenation and dehydrogenation of organics.
Our educational research subjects are alkaline water electrolysis, polymer electrolyte water electrolysis, direct electrohydrogenation of toluene for energy carrier synthesis, which produce hydrogen or chemicals using renewable electricity and polymer electrolyte fuel cells, which is a hydrogen utilization technology. Especially, we focused on the analysis of electrocatalyst degradation mechanisms and the development of low or none precious metal oxide oxygen electrocatalysts to use fluctuated renewable electricity.
