A review of the most efficient low-Pt and Pt-free electrocatalysts for hydrogen PEMFCs
(2013)
The main target of the PEMFC's scientific community is to reduce the total Pt loading to ca. 150 g cm-2 MEA, maintaining simultaneously high PEMFCs performances. The last years, promising results have also been reported ...
PEM vs. AEM fuel cells fed with hydrogen or hydrogen-rich alcohols: Physico-electrochemical phenomena and performance characteristics
(2013)
This review focuses on: (a) describing the physicoelectrochemical transport phenomena in alkaline Anion Exchange Membrane Fuel Cells (AEMFCs) and acidic Proton Exchange Membrane Fuel Cells (PEMFCs) fed with hydrogen or ...
Preparation of graphitic mesoporous carbon for the simultaneous detection of hydroquinone and catechol
(2013)
A graphitic mesoporous carbon (GMC) had been successfully synthesized using Ni-Fe layered double hydroxide (LDH) as both template and catalyst under a relatively low pyrolysis temperature. The techniques of X-ray diffraction, ...
PdxRuy/C binary catalysts for glucose electrooxidation
(2013)
PdxRuy/C (x:y=1:2, 1:3, 2:1 and 3:1) electrocatalysts are prepared by a modified pulse microwave assisted polyol method and are studied for glucose electrooxidation in alkaline media. The effects of glucose's concentrations ...
PEMFCs and AEMFCs directly fed with ethanol: a current status comparative review
(2013)
The last decade's research on the performance of proton-exchange membrane direct ethanol fuel cells (PEM-DEFCs) and anion exchange membrane direct ethanol fuel cells (AEM-DEFCs) is included in the present review. Future ...
Conductivity of Gd-doped BaCeO3 protonic conductor in H2-H2O-O2 atmospheres
(2013)
This work proposes a radically new simple method of evaluation of the proton conductivity based on measurement of the conductivity of ceramic materials depending on the oxygen partial pressure (pO2) at a gradual transition ...
Ethanol Steam Reforming in a Two-Step Process. Short-Time Feasibility Tests
(2013)
This paper describes a two-step process for hydrogen generation consisting of low-temperature (573 K) dehydrogenation of ethanol over copper chromite, followed by steam reforming (SR) over Ni/MgO at higher temperature (923 ...
New mixed ionic-electronic composite materials based on SRTI0.5FE0.5O3-Δ and CE0.8(SM0.8SR0.2)0.2O2-Δ

The crystal, electrical and electrochemical properties of the new composite materials of (1-x)SrTi0.5Fe0.5O3-δ-xCe0.8(Sm0.8Sr0.2)0.2O2-δ (0≤x≤1, Δx= 0.25) prepared by solid phase method. Composites have no phase interaction. ...
Novel composite solid state electrolytes on the base of BaCeO3 and CeO2 for intermediate temperature electrochemical devices
(2013)
In the present work, nano-sized powders of (1-x)Ce0.8Sm0.2O2-delta-xBaCe(0.8)Sm(0.2)O(3-delta) (x = 0, 0.3, 0.5, 0.7 and 1) were obtained by solution combustion synthesis (self-combustion synthesis, SCS) method of nitrate ...
Performance modeling of an alkaline anion exchange membrane-based direct glucose fuel cell
(2013)
An AEM-based DGFC performance model is developed and compared against literature experimental results. Performance predictions for different anode and PtAg/C cathode catalysts, using the 1-D flux-based model, are reported. ...
