    ABSTRACT: Cyclic voltammetry and differential electrochemical mass spectrometry (DEMS) have been combined to study the cycling performance of the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) at a gold electrode in non-aqueous dimethyl sulfoxide (DMSO) and N-methyl-2-pyrrolidone (NMP) based LiClO4 and N(Bu)4ClO4 containing electrolytes. An Au-sputtered Teflon membrane (with a thickness of Au of only 50 nm resulting in an extremely short pore length on the electrolyte side) has been used as a model for a gas diffusion electrode (GDE) in this study: The oxygen molecules diffuse through a membrane from the gas side and are reduced at Au on the electrolyte side. The redox couple O2 −•/O2 is the redominant reaction during ORR in N(Bu)4ClO4 based electrolytes whereas the calculated number of electron transferred is one. In presence of Li-ions, the average number of electrons transferred is 2 during oxygen reduction, which indicates the formation and oxidation of peroxide during ORR and OER respectively. The mass spectrometric cyclic voltammograms (MSCVs) data show that the maximum true coulombic efficiency of OER/ORR in DMSO and NMP is about 60% and 25%, respectively, with the evolution of CO2 in NMP at 0.1 V (vs. Ag+/Ag) due to the decomposition of the electrolyte.

    ABSTRACT: An elementary kinetic model is developed and applied to explore the influence of sulfur poisoning on the behavior of solid oxide fuel cell (SOFC) anodes. A detailed multi-step reaction mechanism of sulfur formation and oxidation at Ni/YSZ anodes together with channel gas-flow, porous-media transport and elementary charge-transfer chemistry is established for SOFCs operating on H2/H2O mixtures with trace amounts of hydrogen sulfide (H2S). A thermodynamic and kinetic data set is compiled from various literature sources. The derived chemical model, validated against sulfur chemisorption isobars taken from literature, is used to analyze performance drops of SOFCs working under typical fuel cell operating conditions. Electrochemical results show that at relatively low H2S concentrations SOFC button-cell performance can be interpreted using chemical sulfur formation. However, when the concentration is sufficiently high, the inclusion of second stage degradation and triple-phase boundary reconstruction is necessary to describe the performance decrease. Additionally, it is shown that the sulfur surface coverage increases with increasing current density. In order to shed more light on advanced fundamental understanding of cell poisoning, sensitive analyses toward total anode resistance and sulfur coverage for different operating conditions were performed.

    ABSTRACT: Energy dispersive X-ray diffraction (EDXRD) with photons of high energy and high flux is used to map crystalline discharge products within alkaline AA cells following discharge at various rates: C/160, C/80, C/40, C/20, C/10, and C/5. During the study, the sealed cells are never opened and thus never exposed to air. The technique’s resolution allows the various manganese oxide discharge products to be distinguished, which has previously proven difficult. In particular, colocalized Mn3O4 (hausmannite) and ZnMn2O4 (hetaerolite) phases are resolved at C/160, C/80, and C/40 rates. Following more rapid discharge at C/20, no hausmannite is observed: instead, two well-defined zones result, one consisting only of hetaerolite, and the other only of α-MnOOH (groutite), with a small transition region where both phases are detected.Modeling suggests the observed hetaerolite-groutite boundary positions are consistent with hetaerolite formation in regions of greater active material utilization. Radial hetaerolite and hausmannite profiles are calculated and found to be a function of the discharge current, which also determines discharge capacity. Results also show formation of a α-MnOOH phase from oxidation states MnO1.7 to MnO1.53 with relatively little γ-MnOOH character.

    ABSTRACT: Metal–supported solid oxide fuel cells with the structure of Ni–Ce0.8Sm0.2O2-δ (SDC) infiltrated porous 430L anode, YSZ electrolyte and in–situ sintered (Bi2O3)0.7(Er2O3)0.3–Ag (ESB–Ag) cathodewas fabricated and a high power density of 1.3Wcm−2 was obtained at 750◦C. Cell performance was enhanced by the Ni–SDC infiltrated porous 430L anode applied here. Replacing the cell electrolyte by SSZ with higher oxide ionic conductivity than that of the YSZ resulted in an improved power density of 1.55 W cm−2 at 750◦C and the improvement was more obvious at the low temperature. Moreover, cell stability was improved by the application of ESB–Ag–La0.74Bi0.10Sr0.16MnO3-δ (LBSM) composite cathode.

    ABSTRACT: The electrochemical behavior of 1-amino-4-hydroxy-9,10-anthraquinone (1-AHAQ) was studied in acetonitrile, dimethyl formamide and dimethyl sulphoxide. In such solvents 1-AHAQ undergoes successive two one-electron reduction forming semiquinone andquinone dianion respectively in which the first step is completely reversible and the second step is quasi-reversible. The reduction and oxidation potentials are dependent on the polarity of the media. The electrochemical parameters are evaluated and correlated with the polarity index of the media. During such reductions a comproportionation reaction operates between the quinone (1-AHAQ) and its dianion (1-AHAQ2–) to form a semiquinone radical (1-AHAQ• –). The apparent comproportionation constants are calculated to find a comparative account on the stability of the radical intermediate in such solvents. In the presence of benzoic acid the electrochemical behavior of 1-AHAQ is altered significantly which is determined in this study. Role of the polarity of the solvents, intra or intermolecular hydrogen bonding and acidic additives on the stability of the radical species is evaluated. In aqueous buffer the reduction of 1-AHAQ follows a one step two-electron process where a kinetic study was carried out to determine the apparent charge transfer rate constants at various scan rates. The results show that electrochemical behavior of 1-AHAQ in non-aqueous and aqueous media mimics the action of anthracycline anticancer drugs which may find a similarity in their biological activities at thecellular level.
