Tohoku Univ. Technology： Analysis of Nano-Microscale Transport Phenomena： S13-012

Large-Scale numerical simulations for development of fuel cells, secondary batteries, semiconductor film formation, etc.

【Fuel cell】 In order to construct a fuel cell system with high efficiency, high durability and low cost, it is necessary to clarify the transport phenomena of proton, oxygen, and water in the cell. By analyzing nano and micro scale flow phenomena and clarifying the correlation between the structural characteristics and the transport mechanism of each component, PEFC performance is expected to be improved. 【Secondary battery】 Due to increasing energy demand and environmental problems, secondary batteries that can be charged and discharged without emitting CO2 or nitrogen oxides are attracting attention. We have a track record of analyzing nano and micro scale flow phenomena such as ion flow in the electrolyte inside liquid and all-solid-state lithium-ion batteries. 【Semiconductor】 For advanced semiconductor devices, controls on the atomic layer level with a thickness error of ±0.5 Å on the wafer is required for the deposition process. In the past, it was necessary to optimize a large amount of experimental data in order to form a precise thin film. At Tokumasu Laboratory, we will elucidate the mechanism through numerical simulation and search for the optimum deposition mechanism.
