Takayuki Terai, Prof., System quantum engineering, Graduate School Engineering course It was when I was in the third grade of elementary school. My class teacher told us we could take back home books that are supposed to be disposed from the library. So I read many books and met biology of scientists like Madame Curie, which helped me be expelled to science. Though I loved Physics, Chemistry and Astronomy, I entered Tokyo University and chose engineering course as I thought it connected to the real world. In 1975, when I entered into atomic engineering in the third grade of university, atomic power plants treating nuclear fission had been commercialized for about 10 years. Troubles at the power plant were on the issue. Nuclear fusion that two atomic nucleuses with less proton and neutron are fused into stable one, which I thought is not more realistic than nuclear fission that one with more proton and neutron fissions into two atomic nucleus. However thinking of futures 30 to 50 years ahead, I thought it might be interesting for my graduation essay. Since then, I've been studying atomic power system, fusion reactor engineering, hydrogen energy system, and fuel cell from hydrogen system. For the theme that hydrogen energy use safe, secured and good for comfortable life, I was working for composition and its application of macromolecule electrolyte film for solid macromolecule fuel cell that works at room temperature, in the "The 21st Century COE Program, Mechanical System Innovation", I succeeded to compose the electrolyte film that has proton conductivity three time as much as available products. Through simulating work for mechanism of the conductivity, I came to find out that cluster of H2O molecule is formed within electrolyte film. Presently, I'm in testing stage of prototype of the fuel cell. My goal for this cell is to overcome disadvantage in cost and durability, and to supply power for mobile phone or PC and even for space or remote areas. Another theme is about development of new catalyst because platinum used as catalyst for fuel cell is limited resource and expensive. I have study that platinum particle gets its diameter to be small to broaden its surface so that reaction efficiency can be improved, I'm also trying to make compound metal from platinum and other metal. I'm engaged in another project that we realize innovation using high energy particles like radiation or plasma. As is known, diamond in nature is formed deep inside of the earth with high pressure and enormous time, If we use plasma, we can make diamond film in a short time. It will be interesting to apply this film to energy system of atomic and hydrogen energy. These two years, I've been stressing on bio suitable material that would help affinity to bio systems of artificial blood tube or catheter or stent improve with high energy particle processing. Speaking of nuclear fusion, I've been keeping it as my study since my university, and I see the possibility of realization of international thermal nuclear fusion reactor(ITER). |
I came up with hints when I was attending meetings or conference, or when I was reading. I take memos on the piece of paper inserted in my pocket notebook. When I'm stuck, for refreshment, I get more sleep, read history of western or Japanese, or renew the web-site of my study room My dream is to contribute to the world through education and study. Material engineering is not so attracting but is one of key technologies. I feel romantic with nurturing people at work as well as my expertise. I want them dressed in sense of management. They should be consciously concerned with the world around. They should set goals and tasks and put it to practice and check and review it, It should be cycled. I want them to produce essay and some things resulting from studies. For that, they should learn how they can produce and control it. It's just life itself. Because life is the piles of projects. |
 High polymer electrolyte film for solid high polymer fuel cell developed in the study class. When simulated by computer, it was proved that the newly developed High polymer electrolyte film (right side)has more H2O clusters formed inside and proton conductivity more increased than current one (left side). |
