from 0.31 m2/g to 0.45 m2/g. The V(Ⅱ)/V(Ⅲ) redox reaction is electrochemically reversible on the TPGF electrode, while the V(Ⅳ)/V(Ⅴ) couple is a quasi reversible process. The diffusion coefficients...: vanadium; redox flow battery; graphite felt; diffusion coefficient. 1 Introduction The vanadium redox flow battery proposed by SKYLLAS-KAZACOS et al[1-3], becomes the most practical candidate......
and aluminum diffusion couple [J]. Intermetallics, 2013, 32: 297-302. [18] LEE K S, KWON Y N. Solid-state bonding between Al and Cu by vacuum pressing [J]. Transactions of Nonferrous Metals Society of China...-based coating was deposited on the pure Al substrate by immersion plating, and the Al/Cu bimetals were prepared by diffusion bonding in the temperature range of 450-550 °C. The interface microstructure......
behavior of Ti-Mo binary system in the β-phase was investigated in the temperature range of 950-1 050 ℃ by using Ti-Mo binary system as diffusion couple. The interdiffusion coefficients were calculated... diffusion couple; interdiffusion; impurity diffusion; activation energy; frequency factor ......
. In the presence of manganese oxide on carbon electrode, the couple Mn3+/Mn4+ reacts with the O2 adsorbed on carbon sites forming radicals and acceletes the dismutation of , which contributes to the catalytic effect of manganese oxide for OR reaction.
Key words: oxygen reduction; manganese oxide; gas diffusion electrode; AC impedance
, and the influences of splicing defects were discussed in detail. The regularities of the effects were studied according to the first order derivation of couple efficiency formula, and a simplified formula for couple efficiency calculation was presented under the circumstance of slight misalignment, with respect to wavelength, λ, and in a good agreement with the theoretical model. The simplified formula......Wavelength dependent loss of splice of single-mode fibers
