为了最大限度地利用不稳定的可再生能源，储能技术的进步必不可少。氢作为一种储存介质，极有可能成为一种主导能源。提出了由燃料电池、水电解槽、金属氢化物储罐及其辅助设备组成的整体式氢能管理系统（THEM-System）。本文首先介绍了金属氢化物储罐的数值分析模型。通过计算结果与实验结果的对比，证实了数值分析计算可以合理地估计5 kW级系统中金属氢化物贮箱的动态特性，并证实了利用该模型可以合理地设计THEM-System中金属氢化物贮箱的结构和运行条件。此外，还介绍了根据不稳定的天气条件进行适当控制的光生电解水系统。使用这种不稳定的氢气供应，金属氢化物氢气罐的特性也进行了数值和实验研究。
In order to carry out the maximum use of unstable renewable energy, progress of energy storage technology is indispensable. Hydrogen which is one of the storage media has a high possibility of becoming a leading energy career. We proposed the totalized hydrogen energy management system (THEM-System) that consists of fuel cells, water electrolyzes, metal hydride tanks and their auxiliaries. Firstly this paper presents the developed numerical analysis model of metal hydride tanks. From the comparison between calculated results and experimental results, it has been confirmed that the numerical analysis calculation can estimate reasonably the dynamics of the metal hydride tank in the 5 kW class system, and moreover, it has been confirmed that by using this model, the structure and the operation conditions of metal hydride tanks can be designed rationally for the THEM-System. Furthermore, Photovoltaic-Water electrolyzer system which performs suitable control in accordance with unstable weather conditions was introduced. Using this unstable hydrogen supply, the characteristic of the metal hydride hydrogen tank is also examined numerically and experimentally.Copyright © 2007 by ASME
