Thermodynamic analysis of a hydrogen fed solid oxide fuel cell based on a proton conductor
(2001)
In the present investigation, the thermodynamic analysis of a solid oxide fuel cell based on protonic electrolyte (SOFC(H(+))) and fed with hydrogen is performed. The influence of such parameters as hydrogen purity, air ...
High temperature electrolyzer based on solid oxide co-ionic electrolyte: A theoretical model
(2007)
In the present work a theoretical model of a solid oxide electrolyzer based on an electrolyte having both oxygen ion and proton conductivity is considered. The main parameters of the electrolytic process and an electrolyzer ...
Degradation of perfluorinated sulfonic acid films: An in-situ infrared spectro-electrochemical study
(2009)
The in-situ Fourier transform infrared (FTIR) spectro-electrochemical method was used to evaluate the degradation mechanism of perfluorinated sulfonic acid (PFSA) polymer for the first time. The effect of H 2O 2 concentration ...
Investigation of the protonic conduction in Sm doped BaCeO3
(2008)
In the present work the structural and electrical properties of samarium-doped barium cerate perovskites of BaCe1-xSmxO3-delta formula (with x=0-0.2), prepared by following the solid state reaction method, are investigated. ...
Ethanol/water mixture permeation through a Nafion (R) based membrane electrode assembly
(2007)
In the present work, the permeation behavior of ethanol/water mixtures through a Nafion((R))- 115 based membrane electrode assembly (MEA) has been investigated. The crossover measurements were carried out in a single fuel ...
Textured BaCe(0.5)Zr(0.3)Ln(0.2)O(3-delta) (Ln = Yb, Y, Gd, Sm, Nd and La) ceramics obtained by the aid of solid-state reactive sintering method

Conductivity of Gd-doped BaCeO3 protonic conductor in H-2-H2O-O-2 atmospheres
(2014)
In the present investigation, a radically new and simple method of evaluation of the proton conductivity is proposed. This method is based on the conductivity measurement of ceramic materials depending on the oxygen partial ...
BaCeO3: Materials development, properties and application
(2014)
The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great ...
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. ...
