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 ...
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, ...
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 ...
New mixed ionic-electronic composite materials based on SRTI0.5FE0.5O3-Δ and CE0.8(SM0.8SR0.2)0.2O2-Δ
(2013)
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. ...
