Conductivity of Gd-doped BaCeO3 protonic conductor in H2-H2O-O2 atmospheres
Medvedev, D.; Murashkina, A.; Demin, A.; Tzorbatzoglou, F.; Tsiakaras, P. (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 ... -
Direct alcohol fuel cells: Challenges and future trends
Brouzgou, A.; Tzorbatzoglou, F.; Tsiakaras, P. (2011)Among the most considered future alternative energy conversion systems are fuel cells. A fuel cell is an electrochemical device that continuously and directly converts chemical energy to electricity with the most common ... -

Tzorbatzoglou, F.; Brouzgou, A.; Tsiakaras, P. (2015)Carbon-supported (Vulcan XC-72) Pd, Rh, and PdxRhy (20 wt%, x:y = 1:1, 3:1, 1:3) electrocatalysts are prepared according a modified pulse-microwave assisted polyol synthesis method and their electrocatalytic activity toward ... -
Exergy Analysis of an Intermediate Temperature Solid Oxide Fuel Cell-Gas Turbine Hybrid System Fed with Ethanol
Stamatis, A.; Vinni, C.; Bakalis, D.; Tzorbatzoglou, F.; Tsiakaras, P. (2012)In the present work, an ethanol fed Solid Oxide Fuel Cell-Gas Turbine ( SOFC-GT) system has been parametrically analyzed in terms of exergy and compared with a single SOFC system. The solid oxide fuel cell was fed with ... -

Preparation of graphitic mesoporous carbon for the simultaneous detection of hydroquinone and catechol
Yuan, X.; Yuan, D.; Zeng, F.; Zou, W.; Tzorbatzoglou, F.; Tsiakaras, P.; Wang, Y. (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, ... -
A review of the most efficient low-Pt and Pt-free electrocatalysts for hydrogen PEMFCs
Tzorbatzoglou, F.; Brouzgou, A.; Tsiakaras, P. (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 ...
