The storage of hydrogen by adsorbent materials has been addressed by several researchers. These materials can serve as a reservoir of hydrogen at a very lower temperature, and the emptying operation to supply the fuel cell is simply heating the adsorbent bed. However, to maximize the ability of the adsorbent materials to meet the instantaneous hydrogen demand, adequate knowledge of desorbed hydrogen flow rate (DHR) must be investigated. The objective of this study is to model the control of the DHR induced by heating. The results show that the excess of hydrogen stored in the adsorbent material can be completely released at room temperature and the DHR increases with temperature. A solution is proposed for stabilizing the DHR, which consists in controlling the fuel cell supply section and, consequently, the power to be produced.

吸附剂材料对氢的储存已被一些研究人员提出。这些材料可以在非常低的温度下用作氢气的储存器，而为燃料电池供电的清空操作仅是加热吸附床。但是，为了使吸附材料满足瞬时氢气需求的能力最大化，必须研究足够的解吸氢气流速（DHR）知识。这项研究的目的是模拟加热引起的DHR的控制。结果表明，在室温下可以完全释放出吸附剂中存储的过量氢，并且DHR随温度升高而增加。提出了一种用于稳定DHR的解决方案，该解决方案包括控制燃料电池的供应部分以及由此产生的功率。
