Silver as Anode in Cryolite—Alumina-Based Melts [PDF]

open access: yes, 2007
The anodic behaviour of silver was investigated in cryolite—alumina-based melt. Silver has a lower melting point (ca. 960◦C) than the other metals considered as possible inert materials for aluminium electrolysis.

Effect of Solution Composition on the Passivation of Anode in Copper Electrorefining

open access: yesJournal of MMIJ, 2017
To elucidate the effect of solution composition on the passivation of anode in Cu electrorefining, the potentiodynamic polarization curves were measured by polarizing from -0.2 V versus NHE to 1.0 V using the potential sweep method at 1.0 mV·s−1.

Influence of power quality and stack temperature on the specific energy consumption of alkaline electrolyzer

open access: yesIET Renewable Power Generation
The efficiency of the power‐to‐hydrogen (P2H) alkaline electrolyzer (AE) is the primary factor constraint on its large‐scale application. Decreasing the specific energy consumption (SEC) of AE is positive to enhancing the efficiency of P2H system ...

Oxidation kinetics of a Ni-Cu based cermet at high temperature [PDF]

open access: yes, 2013
The oxidation kinetics of a cermet composed of Ni–Cu alloy and nickel ferrite was studied by thermogravimetry at 960 °C under oxygen in the range 0.5–77 kPa. After an initial mass increase up to 15 g/m2 due to oxidation of surface metallic particles, the
