금속수소화물(DiNi5-H2 system)의 수소 흡수-방출 특성과 반복 효과에 관한 연구
A Study on the Cycling Effects and the Hydrogen Absorption-Desorption Characteristics Of Metal Hydrides (DiNi5-H2 system)
초록
이 논문은 새로운 에너지 개방을 위한 금속수소화물에 대한 기초연구를 요약한 것이다. DiNi5 합금의 수소 흡수 및 탈착 특성을 조사하였다. 30℃에서 DiNi5 합금의 최대 수소흡착량은 H/M=1.04였고 30℃에서 히스테리시스가 가장 작았다. 이 합금의 수소 흡 ·탈착 능은 우수하였다. 30℃에서 수소의 흡 ·탈착 반복회수는 약 9000번 정도 였으며, 수소 탈착속도는 40℃에서 최대를 보였다.
This paper summarizes fundamental research on a metal hydrides for the development of new energy. We made a study of the characteristics of the hydrogen absorption-desorption of DiNi5 alloys. As a result, we found that the maximum amount of the hydrogen absorption of DiNi5 alloys (the maximum in the absorption equilibrium pressure section) was H/M=1.04 at 30℃. The hysteresis was the smallest at 30℃. The capability of the hydrogen absorption-desorption was excellent. The number of cycles of the hydrogen absorption-desorption was about 9000 times at 30℃. We found also that the rate of the hydrogen desorption was the largest at 40℃.
