Composites of LSCF(La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_{3-delta} and CGO(gadolinium doped ceria) is an efficient candidate cathode material with CGO electrolytes. In this study, LSCF with exact perovskite structure was synthesized by using solid state reaction(SSR) method. The optimized temperature to synthesize La_{0.6}Sr_{0.4}Co_{0.2}Fe_{0.8}O_{3-delta} with rhombohedral structure. was 1100?C. The polarization resistance of the LSCF/CGO(50:50 wt.%) was smaller than those of other composite cathodes. The analysis of the EIS data of LSCF/CGO suggests that the diffusion and adsorption-desorption of oxygen can be the key process in the cathodic reaction of SOFC using LSCF/CGO as cathode material.

Membrane reactors have been showing a promising future and attracted increasing attention in the scientific community as they possess advantages in terms of enhanced catalytic activity and selectivity, combination of processes (reaction and separation), simplicity in process design, and safety in operation. In particular, solid electrolyte membrane reactor principles are realized in fuel cells, electrolyzers and reactors for hydrogenation of carbon dioxide and other economically viable reactions.

LCD TV와 컴퓨터 모니터에는 스크린을 밝게 할 목적으로 냉음극관이 장치되어 있는데 이러한 냉음극관 대부분에는 수은이 봉입되어 있으므로 폐 LCD의 재활용 시 적절히 취급되어야 한다. 아울러 이러한 폐 LCD내의 냉음극관의 처리는 2002년에 채택된 EU의 WEEE 와 RoHS 지침에 따라 취급되고 제거되어야만 한다. 본 연구에서는 폐 LCD의 몰드 프레임에 장착된 CCFL을 안전하고 효율적으로 제거한 다음 여기 함유된 수은과 형광체 화합물을 환경친화적으로 분리하여 무해화 처리할 수 있는 건식 공정을 개발하였다. 이를 통해서 실용적이고 경제성 있는 폐디스플레이 자원 재활용 통합공정 개발에 기여할 목적으로 CCFL 무해화 시스템의 설계 및 제작, 이를 운용한 수은/형광체 화합물의 환경친화적 무해화 처리 효율을 평가해 보았다. CCFL 무해화 시스템을 이용하여 처리된 CCFL내 잔류 수은의 양을 정량적으로 평가해 본 결과 무해화율 99% 이상을 달성하였다. LCD televisions and monitors use cold cathode fluorescence lamps (CCFLs) to illuminate the screen. Most CCFLs contain mercury and they have to be carefully handled at the end of their lives as per minimum treatment standards under the Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances (RoHS) directives. CCFLs were carefully separated from mold frames of waste LCD units for primary decontamination of mercury/fluorescent compound mixture using CCFL decontamination system designed and fabricated in the present research. Residual mercury was further removed by employing a pyro-process, where crushed CCFL tubes transferred from primary decontamination process were subject to heat treatment at $550^{\circ}C$ in a box furnace: more than 99% of mercury was removable from waste CCFLs.

KIER has been developing the anode supported flat tubular SOFC stack for the intermediate temperature (700~800℃) operation. For this purpose, we have first fabricated anode supported flat tubular cells by the optimization between the current collecting method and the induction brazing process. After that we designed the compact fuel & air manifold by adopting the simulation technique to uniformly supply fuel & air gas and the unique seal & insulation method to make the more compact stack. For making stack, the prepared anode-supported flat tubular cells with effective electrode area of 90 ㎠ connected in series with 12 modules, in which one module consists of two cells connected in parallel. The performance of stack in 3 % humidified H2 and air at 800℃ shows maximum power of 507 W. Through these experiments, we obtained basic & advanced technology of the anode-supported flat tubular cell and established the proprietary concept of the anode-supported flat tubular SOFC stack in KIER.

국내 디스플레이 산업의 핵심기술과 글로벌 점유율은 세계 최고 수준이지만 폐 디스플레이의 재활용 관련한 전반적 기술은 매우 미흡하고 폐 디스플레이의 유리소재는 전량 매립하고 있는 실정이다. 본 논문에서는 폐 초박막 액정표시장치(Thin Film Transistor Liquid Crystal Display) 유리를 고강도 콘크리트 파일 및 발포체의 원료로 재활용 하는 연구, 초박막 액정표시장치 제조 공정에서 발생하는 불량품인 파유리를 장섬유 및 단섬유 등으로 재활용 하는 연구 동향에 대하여 조사하였다. 폐유리를 재활용한 원료 성분은 고강도 콘크리트 파일과 발포체 원료로 재료 재활용이 가능한 것으로 입증되었으며 특히 콘크리트 파일의 경우 기존 제품보다 향상된 특성을 나타내었다. 이외에도 파유리를 장섬유나 단섬유로 재활용 하는 기술은 이미 상용화 단계에 있으므로 향후 폐 디스플레이 유리 소재의 상용화 재활용 시스템을 구축할 수 있는 기술을 확립하는 방향으로 연구를 진행할 필요가 있다. Although Korea is a top market sharing and world leading producer and developer of flat panel display devices, relevant recycling technology is not up to her prestigious status. Besides, most of the waste glass arising from flat panel displays is currently land-filled. The present paper mainly reviews on development of recycling systems for waste TFT-LCD glass from end-of-life LCD TVs and monitors and TFT-LCD process waste of crushed glass particles with target end uses of raw material for high strength concrete pile and glass fibers, respectively. Waste LCD glass was recycled to fabricate ingredients for high strength concrete piles with enhanced physical properties and spherical foam products. The waste LCD glass recycling technology is already developed to fabricate long and short fibers at commercial level. In view of these, future R & D on waste LCD glass materials is to be directed toward implementation of commercial materials recycling system therefrom.
