Effects of cyclic hydriding–dehydriding reactions of Mg2Ni alloy on the expansion deformation of a metal hydride storage vessel

Experimental investigation of the swelling/shrinkage of a hydride bed in a cell during hydrogen absorption/desorption cycles

“…(14)) corresponds to the difference between the volume occupied in the hydrided state (V H k ) and the unhydrided state of the following cycle indexed kþ1 (V U kþ1 ). (14) For the hydriding in cycle 7 (Eq. (15)), the situation is rather different, because the initial volume corresponds to the unhydrided state (V 0 7 ).…”

A tool for modelling the breathing of hydride powder in its container while cyclically absorbing and desorbing hydrogen

“…The stress level predicted by the model should then be compared to experimental values, like those obtained in the literature [16,22,24,49]. The realism of particle shapes and particle size distribution could be improved using particles packing inspired from 3D tomography imaging of hydride powder samples.…”

Review of thermal management technology for metal hydride reaction beds

“…179 Aer multiple cycles of hydrogen charge and discharge, the number of small particles increases and they gradually accumulate at the bottom of the MHR, leading to powder agglomeration, which not only causes a decrease in the amount of hydrogen absorbed and released but also causes dramatic stress. 180 Long-cycle mechanical stability of the MHB is maintained by pressing treatment. 141,181 The joining of foams, ENG, aluminum powder, etc., can also play a role in hindering the agglomeration of MH powder.…”
