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 ...
Thermal expansion of materials in the barium cerate-zirconate system
(2015)
The thermal expansion of proton-conducting materials in the BaCe0.8 - x Zr (x) Y0.2O3 - delta system has been investigated in air. The influence of the zirconium concentration and the measurement mode (heating/cooling) on ...
Investigation of the structural and electrical properties of Co-doped BaCe0.9Gd0.1O3-delta
(2011)
In the present work the effect of cobalt oxide addition on the density and on the electrical properties of gadolinium-doped barium cerate is investigated. A series of BaCe0.9-xGd0.1CoxO3-delta (x = 0.00, 0.01, 0.03, 0.05, ...
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 ...
