  • Optimizing hydrogen storage in TiFe–V alloys: Influence of sample purity and heat treatment
    Satya Prakash Padhee, Kouji Sakaki, Vivek Shukla, Kyubin Hwang, Young Whan Cho, Young-Su Lee
    International Journal of Hydrogen Energy, 2025
    This study investigates the hydrogen storage properties of titanium-iron (TiFe) alloys with vanadium (V) addition, using industrial-grade materials. The research aims to optimize TiFe–V alloys for practical hydrogen storage applications by improving activation kinetics, maximizing useable capacity, and enhancing long-term stability. Three compositions—Ti 48 Fe 47 V 5 (V5), Ti 47 Fe 47 V 6 (V6) and Ti 46 Fe 47 . 5 V 6.5 (V6.5)—were examined to assess their response to heat treatment and purity of raw materials. The addition of 3 wt% Ce to low-purity alloys effectively prevents the formation of the Ti 4 Fe 2 O x phase, increasing the B2 phase proportion and improving hydrogen storage capacity. Mischmetal (Mm) addition similarly reduced the Ti 4 Fe 2 O x phase and enhanced activation kinetics, offering a cost-effective alternative to Ce. Short-term heat treatments (4–8 h) at 1000 °C were found to dissolve 60–80 % of the C14 phase into the B2 matrix, enabling efficient production without the need for prolonged homogenization. The Mm-added V6.5 alloy, after 8 h of heat treatment, demonstrated fast hydrogen absorption at 40 °C and achieved a useable capacity of approximately 1.44 wt%. These results indicate that Ce and Mm additions, combined with optimized heat treatment, can facilitate the scalable production of TiFe alloys with high hydrogen storage performance.

    In the present study, we aimed to destabilize the Ti–Al system with nonmetallic oxygen. The synthesis of α‐(Ti, Al)[O] starting from TiO2, Ti, and Al was carried out through the arc melting method, resulting in three different oxygen content levels, 3.4, 10, and 20 at%. The room temperature activation of α‐(Ti, Al)[O] was not successful, and the activation was performed at 300°C under 5 MPa H2 pressure. The structural changes after hydrogenation (maximum absorption capacity of 3.74 wt% hydrogen) arose from the transformation of α‐(Ti, Al)[O] to cubic (Ti, Al)[O]Hx (c‐(Ti, Al)[O]Hx); nonetheless, they recovered their original lattice parameters, which are meaningfully larger than those of α‐Ti, after dehydrogenation. The hydrogen storage capacities for various α‐(Ti, Al)[O] compositions generally decreased with increasing oxygen (3.4 and 10 at%) and aluminum content in the alloy. In contrast, for the compositions with a higher oxygen content of 20 at%, the hydrogen storage capacity slightly increased as the Al concentration increased: Ti0.790Al0.010O0.200 absorbed 2.91 wt% hydrogen, whereas Ti0.767Al0.033O0.200 absorbed 3.04 wt% hydrogen. The thermogravimetric analysis showed that samples with 20 at% O released hydrogen at lower temperatures even though the major phase after hydrogenation is c‐(Ti, Al)[O]Hx regardless of the oxygen content.

    In here, we report on the pulse electrodeposition of nickel–chromium–phosphorous (Ni–Cr–P) coatings on AISI 1020 low carbon steel using an aqueous electrolyte consisting of NiCl2, CrCl3, and NaH2PO2. We evaluated the effectiveness of Ni–Cr–P coatings for polymer electrolyte membrane fuel cell metallic bipolar plates. Coatings deposited at pH 3.0 and room temperature show nearly three orders improvement in corrosion resistance compared to bare AISI 1020. The corrosion current (Icorr) of Ni–Cr–P samples coated at 25 °C is 1.16 × 10−4A/cm2, while that of bare carbon steel is 1.05 × 10−2A/cm2. The improvement in corrosion resistance is due to the increase in Cr content in the Ni–Cr–P coatings. Cr forms a stable oxide barrier layer and inhibits pitting corrosion. The interfacial contact resistance increases with an increase in Cr content and immersion time in the corrosion media. The increase in interfacial contact resistance is also due to the formation of a stable oxide barrier.
