Investigation on the physical and electrochemical properties of typical Ni-based alloys used for the bipolar plates of proton exchange membrane fuel cells

Investigation of the Performance of Hastelloy X as Potential Bipolar Plate Materials in Proton Exchange Membrane Fuel Cells

“…Hastelloy X exhibits a WCA value of 79.5°, which is larger than that of 304SS (76.2°). Meanwhile, the hydrophobicity of Hastelloy X was significantly better than in our previous studies on Hastelloy C-276 and Hastelloy B [25]. However, both of the WCA values of Hastelloy X and 304SS are less than 80°, indicating poor hydrophobicity.…”

Unravelling the effect of paramagnetic Ni2+on the13C NMR shift tensor for carbonate in Mg2−xNixAl layered double hydroxides by quantum-chemical computations

“…Layered double hydroxides (LDH) are a class of layered inorganic ionic solids characterised by the general formula M( ii ) 1− x M( iii ) x (OH) 2 An x / n · y H 2 O, where M( ii ) [M( iii )] is a divalent [trivalent] cation in the metal hydroxide layers, the layers are separated by an interlayer containing anions (An) with a charge of n − and a variable amount of water. 1–3 The M( iii ) content, x , ranges between 1/6 and 1/3, hence these materials are often referred to as “M( ii )M( iii )-LDH”. The anions are weakly bound and highly exchangeable, which renders LDH a rare example of anion-exchange materials, 4–7 and therefore allows potential use for, e.g.…”
