Steady State Simulation Of Ysz Intermediate-Temperature Fuel Cell, Zi-Jing Lin, Ye Gu, Xiao-Hua Zhang

Journal of Electrochemistry

With a coupled 2D electrochemical and thermal modeling software, the characteristics of the steady state operation of the intermediate-temperature fuel cell with thin yttria-stabilized zirconia(YSZ) electrolyte was analyzed. The parameters of I-V equation were obtained from fitting the experiment results and the choice of grid points was determined by balancing the accuracy requirement and computational efficiency. The temperature fields at different operation circumstances such as flow designs, material choices for interconnect, were examined. The dependences of the output power and cell efficiency on the operating voltage at different temperatures were studied. Based upon the analysis of the temperature profile, it …

Mechanistic Study Of Oxidation Of Hypophosphite On Pt Electrodes By Sniftirs, Tai-Xiang Jiang, Hui-Huang Wu

Journal of Electrochemistry

The oxidation of hypophosphite on a polycrystalline platinum electrode was studied by SNIFTIRS and cyclic voltammetry, the in-situ IR spectra were analyzed as a function of Pt electrode potentials in the solution of 0.5 mol/L H₂SO₄+0.1 mol/L NaH₂PO₂. It was found that the dissociative adsorption of hypophosphite ions occurs on Pt surface, and the oxidation product is H₃PO₄, rather than H₂PO₃^- which was considered to produce on Ni electrodes, thereby a new insight into mechanism of hypophosphite oxidation on Pt in acidic media was …

Studies On The Inhibition Of Yki-05 Corrosion Inhibitor To 907a Steel In Different Immersed Environments, Hui Yu, Jian-Hua Wu, Hong-Ren Wang, Jian-Hua Qian, Guang-Zhang Chen

Journal of Electrochemistry

The inhibition of YKI-05 Corrosion inhibitor in different conditions was studied using potentiodynamic polarization technique. The resuled shown that (i) the inhibitor film layer was formed stably on the surface of 907A steel electrode when it was persistently immersed in static seawater and the inhibition efficiency reached 90% or so. The inhibition mechanism is negative catalytic effect. (ii) the inhibitior film layer was not stable when the electrode was periodically immersed in seawater and was destroyed more significantly with the increase of electrode exposing time. The film was only a covered layer on the surface of electrode and it retarded …

Preparation And Performance Of Lifeo2 Coated Nickel Oxide Cathode For Molten Carbonate Fuel Cells, Chun-Ming Wang, Fei Li, Ke-Ao Hu

Journal of Electrochemistry

A novel cathode for molten carbonate fuel cells was prepared by coating LiFeO₂ over the surface of porous NiO cathode by a simple combustion process. The analytical results of X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDAX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated that the LiFeO₂ coating on the surface of NiO particles consisted of nonometer-sized LiFeO₂ grains and sintered tightly with the NiO particles. The LiFeO₂ coating dramatically reduced the contacting area of NiO with the carbonate melts, thus the solubility of NiO in the carbonate melts was decreased. Meanwhile, …

Electrocatalytic Oxidation Of Formic Acid On Molybdate-Modified Platinum Electrode, Jun-Hua Du, Xue-Hui Xu, Hong Li, Hong-Yu Cheng, Wei-Shan Li

Journal of Electrochemistry

The electrochemical behavior of molybdates on a platinum electrode in H₂SO₄ solutions with different H₂SO₄ concentrations was studied by cyclic voltammetry and double chronoamperometry. Molybdates were reduced to adsorb hydrogen molybdenum bronzes on the platinum electrode in H₂SO₄ solutions during cathodically potential sweep. The hydrogen molybdenum bronzes were oxidized to different forms of hydrogen molybdenum bronzes with less hydrogen, depending on the H₂SO₄ concentration. Platinum electrode was modified by these hydrogen molybdenum bronzes. However, this modified electrode was not stable in H₂SO₄ solutions. The modified …

Manufacture Of 1 Kw Molten Carbonate Fuel Cell Stack, Sheng Sui, Xin-Jian Zhu, Zheng-Yu Fan, Guang-Yi Cao

Journal of Electrochemistry

A molten carbonate fuel cell stack with an active area of 240 mm×140 mm consisted of 30 cells. The gas feed system works via interior manifolds, and the stack placed in a couple of self-chest, coupled with a heater at the bottom and other fours surrounded,to keep uniformity of temperature.Under ambient pressure and 650 ℃, fed with hydrogen and air as anode and cathode gases respectively, the stack gave a current density of 150 mA/cm² at an average cell voltage of 0.7 V. The peak output of the stack was 1.06 kW during its performance of 300 h.

The Galois Correspondence For Branched Covering Spaces And Its Relationship To Hecke Algebras, Matthew Ong

Mathematical Sciences Technical Reports (MSTR)

There is a very beautiful correspondence between branched covers of the Riemann sphere P¹ and subgroups of the fundamental group π₁(P¹ − {branch points}), exactly analogous to the correspondence between subfields of an algebraic extension E/F and subgroups of the Galois group Gal(E/F). This paper explores the concept of a Hecke algebra, which in this context is a generalization of the Galois group to the case of non- Galois covers S/P¹. Specifically, we show that the isomorphism type of a Hecke algebra C[H\G/H] is completely determined by the decomposition of …

Analysis Of Longitudinal Marginal Structural Models , Jennifer F. Bryan, Zhuo Yu, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

In this article we construct and study estimators of the causal effect of a time-dependent treatment on survival in longitudinal studies. We employ a particular marginal structural model (MSM), and follow a general methodology for constructing estimating functions in censored data models. The inverse probability of treatment weighted (IPTW) estimator is used as an initial estimator and the corresponding treatment-orthogonalized, one-step estimator is consistent and asymptotically linear when the treatment mechanism is consistently estimated. We extend these methods to handle informative censoring. A simulation study demonstrates that the the treatment-orthogonalized, one-step estimator is superior to the IPTW estimator in terms …

Stolen Generations And Vanishing Indians: The Removal Of Indigenous Children As A Weapon Of War In The United States And Australia, 1870-1 940, Victoria Haskins, Margaret D. Jacobs

Department of History: Faculty Publications

As a central component of the assimilation agenda in the United States and of absorption plans in Australia, child removal became a systematic government policy toward indigenous peoples in both countries in the nineteenth and twentieth centuries. Using the rhetoric of protecting and saving indigenous children, reformers and government officials touted child removal as a means to "uplift" and "civilize" indigenous children. Modern-day historians, until very recently, have characterized child removal in similar ways: as a well-intentioned, though ultimately misguided, alternative to warfare and violence against indigenous peoples.

If we turn our attention to the perspectives of the indigenous peoples …

Proofs Of Soundness And Strong Normalization For Linear Memory Types, Heng Huang, Chris Hawblitzel

Computer Science Technical Reports

Efficient low-level systems need more control over memory than safe high-level languages usually provide. As a result, run-time systems are typically written in unsafe languages such as C. This report describes an abstract machine designed to give type-safe code more control over memory. It includes complete definitions and proofs.
