Solid oxide fuel cells (SOFCs) can be operated in a reversed mode as electrolyzer cells for electrolysis of H2O and CO2. In this paper, a 2D thermal model is developed to study the heat/mass transfer and chemical/electrochemical reactions in a solid oxide electrolyzer cell (SOEC) for H2O/CO2 co-electrolysis. The model is based on 3 sub-models: a computational fluid dynamics (CFD) model describi...

The electrochemical reduction of 1-([(4-halophenyl)imino]methyl)-2-naphthols on graphite electrodes was studied using cyclic voltammetry, chronoamperometry, constant-potential coulometry and preparative constant-potential electrolysis techniques. The data revealed that the reduction on graphite was irreversible and followed an EC mechanism. The diffusion coefficients and the number of electrons...

We show that energetic charged particles are produced during electrolysis of a D2O solution of Li2SO4 in a cell with a platinum anode and a palladium cathode. CR-39 plastic detectors, designed for recording alpha particles from radon decay, were immersed in the electrolyte during electrolysis. They recorded significantly larger numbers of energetic particle tracks than were recorded by control ...

Electrical field stimulation of isolated, incubated rodent skeletal muscles is a frequently used model to study the effects of contractions on muscle metabolism. In this study, this model was used to investigate the effects of electrically stimulated contractions on creatine transport. Soleus and extensor digitorum longus muscles of male NMRI mice (35-50 g) were incubated in an oxygenated Krebs...

1. In t roduct ion Electrolytic coloring, electrodeposition coating and several other surface finishing techniques for anodized aluminum have been performed by applying secondary and sometimes tertiary electrolysis to anodized aluminum. Upon applying secondary electrolysis to anodized aluminum, thc understanding of (1) the pore filling theory, (2) flaw theory and (3) current recovery phenomena ...

Electrolysis in Pd-LiOD(H), NaOD(H) and KOD(H) systems was carried out to clarify the specific role of the lithium for tremendously high density and the dynamic movement of the deuterium on the surface of the Pd cathode. Only for LiOD system with pulse mode current electrolysis, anomalous high density of deuterium and lithium and the dynamic movement of deuterium are observed on the surface of ...

Excess heat was produced at the rate of about 1.2 watts during electrolysis of heavy water with a titanium cathode weighing 0.0625 g. Analysis of the electrodes before and after electrolysis with a scanning electron microscope (SEM) and an energy dispersive spectrometer (EDS) revealed that new surface topographical features with concentrations of unexpected elements (S, K, Ca, V, Cr, Fe, Ni, an...

Through a variety of material screening experiments, Al was selected as the added metal and constituted a multiple micro-electrolysis system of Fe/C/Al. The metal proportion of alloy-structured filler was also analyzed with the best Fe/C/Al ratio of 3:1:1. The regular Fe/C/Al multiple micro-electrolysis fillers were prepared using a high-temperature anaerobic roasting method. The optimum condit...
