چکیده
The Ni/YSZ composite electrode is conventionally used for solid oxide cells, in electrolysis (SOEC) as well fuel cell (SOFC) operation. For enhanced durability and C-tolerance, alternative materials are needed. In this paper, we compare the performance of two distinct Ni:CGO electrocatalyst coated A-site deficient lanthanum doped strontium titanate (La 0.4 Sr Fe 0.03 Ni Ti 0.94 O 3 , LSFNT) based anodes, integrated into metal supported cells (MSCs), to SoA anode mode first time. three were investigated electrochemically by impedance spectroscopy (EIS) under applied current (iV-curves) at temperatures 750˚C, 700˚C, 650˚C, novel 620˚C steam/hydrogen methane/steam. Additionally, one MSCs was CO/steam. Furthermore, galvanostatic tests conducted 4% MS-cells low temperature (650˚C) medium-high utilization (50%).

Numerical Modeling of Single-Chamber SOFCs with Hydrocarbon Fuels
A two-dimensional numerical model of a single-chamber solid oxide fuel cell SCFC operating on hydrocarbon fuels is developed. The SCFC concept is a simplification of a conventional solid oxide fuel cell in which the anode and cathode are both exposed to the same premixed fuel-air mixture, and selective catalysts promote electrochemical oxidation of the fuel at the anode and simultaneous electro...
متن کاملBi-Based Oxide Anodes for Direct Hydrocarbon SOFCs at Intermediate Temperatures
Doped Bi-based oxides were investigated as potential anode materials for direct hydrocarbon solid oxide fuel cells ~SOFCs! at intermediate temperatures. (Bi2O3)0.85(Ta2O5)0.15 met this criterion most successfully. A fraction of Bi2O3 in this material was reduced to BiO and Bi metal under fuel conditions, which yielded high conductivities ~,1 S cm! based on oxide ions and electrons above 500°C. ...

Background: Although anaerobic system has been successfully used for treating the strong industrial wastewater, its efficiency for low-strength wastewater as municipal wastewater is not satisfying. This study aimed to enhance the capability of an anaerobic baffled reactor (ABR) for treating municipal wastewater. Methods: A 7-L ABR with 5 compartments was operated for a 287-day period fed with ...

Pressure-induced superconducting state of europium metal at low temperatures.
Divalent Eu (4f;{7}, J=7/2) possesses a strong local magnetic moment which suppresses superconductivity. Under sufficient pressure it is anticipated that Eu will become trivalent (4f;{6}, J=0) and a weak Van Vleck paramagnet, thus opening the door for a possible superconducting state, in analogy with Am metal (5f;{6}, J=0) which superconducts at 0.79 K. We present ac susceptibility and electric...
