Effect of activation procedure on Sm-Co-Fe-Zr-B compound for low temperature efficient hydrogen storage
S. S. Makridis, Ch. N. Christodoulou, E. S. Kikkinides +1
The present research work is focused on the effect of activation procedure on the hydrogen absorption-desorption properties of new rare earth transition metal compound based on Sm(…
Structure, microstructure and hydrogen storage properties of melt-spun V55Ti21Cr17Fe7 and V55Ti21Mn17Fe7
A. Ioannidou, S. S. Makridis, M. Gjoka +4
The hydrogen sorption performance of V55Ti21Cr17Fe7 and V55Ti21Mn17Fe7 alloys and their ribbons were evaluated by pressure composition temperature tests. Their hydrogen absorption…
Perforation Effect on a Rectangular Metal Hydride Tank for the Hydriding and Dehydriding Process by Using COMSOL Multiphysics Software
E. I Gkanas, S. S Makridis, E. S Kikkinides +1
In this paper, a 3 Dimensional dynamic model of a perforated rectangular metal hydride tank is presented. The metal hydride tank consists of powder LaNi5 and the tubes are organize…
Two-stage Hydrogen Compression Using Zr-based Metal Hydrides
Evangelos Koultoukis, Sofoklis Makridis, Daniel Fruchart +1
Zr-based AB2-Laves phase type alloys containing the same type of A and B metals, have been prepared from pure elements by melting and subsequent re-melting under argon atmosphere b…
Synthesis and Characterization of TiFe0.7-xMn0.3Vx (x=0.05, and 0.1) and Ti1-yTayFe0.7Mn0.3 (y=0.2, and 0.4) Nanostructured Metal Hydrides for Low Temperature Applications
N. G. Anagnostou, S. S. Makridis, E. S. Kikkinides +2
Metal hydrides (MH) are often preferred to absorb and desorb hydrogen at ambient temperature and pressure with a high volumetric density. These hydrogen storage alloys create promi…
Synthesis, Structural, Electrical and Microchemistry Properties of Novel (LSCFM) LaxSr1-xCo1-y-zFeyMnzO3-δ (x=0.4, 0.6, 0.8, y=0.4, 0.8 and z=0.1, 0.2) Perovskites for SOFC Applications
E. A. Tsiligkeridis, S. S. Makridis, E. Pavlidou +2
Perovskites are mixed oxides with the general formula ABO3. Many different compositions have been found to be possible and their number is growing rapidly due to their characterist…
