Materials and Chemical EngineeringMaking fuel cells a more familiar energy systemDivision of Chemistry and MaterialsI am developing two types of fuel cells that do not use platinum, which is expensive, as a catalyst. One is a solid oxide fuel cell (SOFC) that operates at high temperatures. The other is polymer electrolyte fuel cell (PEFC) that uses a non-platinum catalyst, specifically silk-derived activated carbon. Reaction activity and transport phenomena for gas, ions, and electrons in the electrodes are important in both cases, and I am working to develop new materials and to optimize the electrode structure.Hiroshi FukunagaAssociate ProfessorAssociate Professor Fukunaga took his current position in 2009 after serving in the Faculty of Textile Science and Technology at Shinshu University as an assistant professor. His principal areas of research include chemical engineering and electrochemistry as regards solid oxide and polymer electrolyte fuel cells.Fuel cells are a dream technology that can extract energy eciently. A growingarray of applications use fuel cells in large-scale power plants, in residential and automotive power systems, and as a power source for portable devices and articial organs.Outlook for researchChemical engineering can be put to use in a wide range of domains, including chemicals, electricity and electronics, automobiles, and energy.Outlook for students after graduationA power-generating device that uses a solid oxide fuel cellAn electrode for a solid polymer fuel cell that my lab created36Materials and Chemical EngineeringFiber as the key to preventing global warming: Working not only to reduce CO2,but also to lower costsDivision of Chemistry and MaterialsI am researching a new technology for separating and collecting CO2 from exhaust fumes. Specifically, by applying an absorbing liquid that reacts with CO2 to the inside of a cylindrical hollow fiber membrane, I hope to absorb only the CO2 from the exhaust gas on the outside. If this technology can be developed, I expect it to lower the cost of separation and collection.Nobuhide TakahashiProfessorAfter obtaining his doctorate at Tokyo University, Professor Takahashi worked as an assistant professor and associate professor in the Faculty of Textile Science and Technology at Shinshu University before taking his current position in 2014. His areas of specialization are chemical engineering and environmental engineering, and he bases his research on the concept that CO2 + water + soil + sunlight + knowledge + technology = happiness.In addition to CO2 separation and collection technology, my research has ramications for tree-planting in dry areas as well as ecient conversion of wood biomass to solid fuel̶all areas that suggest it has immediate application to solving environmental and energy problems and contributing to the prevention of global warming.Outlook for researchGraduates pursue diverse paths in addition to employment at chemical plant manufacturers and water treatment technology companies.Outlook for students after graduationA student analyzes the process of absorbing CO2 using a hollow ber membrane to compare its eectiveness. Students designed the absorption and diusion device themselves and carry out their own experiments.Students are examining the eects of membrane pore size and surface shape on CO2 absorption.Research and development on a new absorbent material based on biomass
