Özet
The hydrogen charge time in metal hydride vessel (MHV) is strongly influenced by the heat transfer from hydride vessel. In this study, the effect of parameters such as reactor geometry and alloy characteristics on hydrogen charge procedure is studied experimentally. In the experimental setup two different types of hydride vessel are designed and manufactured. Both vessels have the same interior volume; the un-finned type vessel cooled with natural convection and the second one was manufactured with fins around the vessel. The temperature variations of the vessel at four locations were measured charging with a range of pressure from 2 to 8 bar. The finned vessel show the lowest temperature increase with the fastest charging time under all charging pressures investigated. The stored hydrogen mass was measured as 0.82, 0.94, 1.15 wt% on un-finned vessel and 0.91, 1.01, 1.24 wt% on finned vessel at 2, 6 and 10 bar respectively. The experimental results show that the charge time of the vessel is considerably reduced, when the used fins manufacture on vessel. Furthermore, the addition of Al to the LaNi5 alloys has caused to reduce the hydrogen charge time and decreased of the stored hydrogen mass.
