Bi4Cu0.2V1.8O11-delta based membrane electrochemical reactors for propane oxidation at moderate temperatures
(2005)
Bi4Cu0.2V1.8O11-delta membrane material was synthesized by following the solid-state method. The oxygen permeation flux at 673 K was found to be 0.5 ml/cm(2) by the use of an external electric power source. The oxidation ...
Performance of a SOFC Powered with External Ethanol Steam Reforming
(2001)
In the present study, a solid oxide fuel cell (SOFC) system was considered being fed by the equilibrium products of the steam reforming of ethanol. The thermodynamic analysis of ethanol steam reforming was undertaken at ...
Energy and exergy analysis of a solid oxide fuel cell plant fueled by ethanol and methane
(2003)
The method of exergy analysis is presented for a SOFC power plant involving external steam reforming and fueled by ethanol and methane. The optimal operation parameters of the integrated SOFC plant are specified after ...
Electrochemical Promotion of Pt During the Oxidation of Ethanol
(2001)
The reaction of ethanol oxidation has been examined over a Pt polycrystalline film deposited on an yttria stabilized zirconia (YSZ) electrochemical reactor. Experiments were carried out at 325 degrees C at atmospheric total ...
Ethanol And Methane Fueled Solid Oxide Fuel Cells: A Comparative Study
(2001)
Ethanol and methane are compared as candidate fuels for generation of electrical power in Solid Oxide Fuel Cells (SOFCs). The thermodynamic analysis of both alternatives was undertaken considering that a SOFC operates with ...
Catalytic and electrocatalytic oxidation of ethanol over a La0.6Sr0.4Co0.8Fe0.2O3 perovskite-type catalyst
(2000)
The catalytic and electrocatalytic behavior of the perovskite-type La0.6Sr0.4Co0.8Fe0.2O3 catalyst was investigated during ethanol oxidation. Experiments were carried out at atmospheric pressure in a fully yttria-stabilized ...
Pt-based anode catalysts for direct ethanol fuel cells
(2004)
In the present work, several carbon supported PtSn and PtSnRu catalysts were prepared with different atomic ratios and tested in direct ethanol fuel cells (DEFC) operated at lower temperature (T=90 degreesC). XRD and TEM ...
Direct methanol fuel cells: Methanol crossover and its influence on single DMFC performance
(2004)
In the present investigation, the methanol crossover rate through Nafion((R))-115 membrane at different temperatures and different concentrations had been investigated in a fuel cell test apparatus by using gas chromatography ...
Influence of sintering additives of transition metals on the properties of gadolinium-doped barium cerate
(2008)
In the present work the effect of MOx (where M =Cu, Ni, Zn, Fe, Co, Ti) addition on the densification behavior and electrical conductivity of BaCe(0.9)d(0.1)O(3-delta) ceramics is investigated. It was found that the small ...
