| 제목 | Stick to New Monolithic Type Solid Oxide Fuel Cells |
| 초록 | Solid oxide fuel cells, that can be operated at the highest possible temperatures of 750-1,000oC, have numerous advantages of the highest electricity generating efficiency, the use of various fuels including coal gasification gas and biogas, and an additional adoptability of gas turbine. However, the high temperature also brings in some critical drawbacks such as sealing, corrosion scale up problems, especially in the typical planar types of cells. For the past 20 years, many different designs of non-planar types, such as tubular, flat tube, and corrugated plate, have been emerged and disappeared. Here, we introduce new ways of designing unit cells of the monolithic type having flat tube structure and of manufacturing stacks using the cells.One type (MEGA cell) is composed of monolithic flat tubes that can be staked in series, and the other type (SEGA cell) is monolithic segmented plat tubes that can be stacked into both parallel and series, for the first time in the world. Showing up is current progress on the manufacturing the unit cells having a size of 30-35 mm in width, 150 -200 mm in length, and 2.5-3.0 mm in thickness, and the latest results on the performance of small scale stacks of an order of 10W.The difficulties in developing new types of cells, necessary materials and manufacturing processes, in a short time period with little experience and accumulated know how, will also be mentioned. |
