Experimental results of an air-cooled lab-scale H2 storage tank based on sodium alanate

Catalytic Influence of Various Cerium Precursors on the Hydrogen Sorption Properties of NaAlH4

“…Consequently, the volume of the material decreases and shrinkage occurs. In fact, agglomeration of NaAlH 4 doped with CeCl 3 was observed after cycling in a tank test 40…”

Nanoscopic Al1−xCex phases in the NaH + Al + 0.02CeCl3 system

“…In [10], a high temperature PEMFC stack was developed specifically for use with NaAlH 4 , with demonstrated service of over 5000 h running at 200 C. The first prototype NaAlH 4 storage tank contained 19 kg of catalyzed NaAlH 4 [11], a thermally optimized tank containing 8 kg of NaAlH 4 was trialed in [12], and NaAlH 4 hydrogenation kinetics were optimized based on cell diameter in [13]. The most recent work utilizes a 304 g labscale tank of NaAlH 4 þ 0.02CeCl 3 [14].…”

Metal hydride hydrogen and heat storage systems as enabling technology for spacecraft applications

“…Although the properties of the metal hydride are vital for final systems performance, they are secondary to technological system implementation since one metal hydride can be readily substituted for another as long this creates no conflict with system parameters. For that reason, we implement the system with 2.5 mol% titanium trichloride doped sodium alanate because the thermal properties of this material are well known and its high cyclic stability has already been demonstrated on various similar applications [6][7][8][9]. However, in order to have a significant advantage over next generation batteries at system level, the cyclic gravimetric hydrogen storage capacity of Ti-doped NaAlH 4 of 3 Á x wt.% should be exceeded as far as possible.…”
