“…To release hydrogen gas to the fuel cell, a desorption process is required by heating the absorbent bed in ambient air at room temperature to increase the pressure of the stored hydrogen [21]. In our system, the adsorption is automatically synchronized with an intermittent solar energy source.…”

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 for fuel cells is simply heating the adsorbent bed. However, in order 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.
