Direct alcohol fuel cells: Challenges and future trends
(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 ... -
Iron-embedded nitrogen doped carbon frameworks as robust catalyst for oxygen reduction reaction in microbial fuel cells
(2017)A kind of 3D Fe-embedded N doped carbon framework catalyst is successfully developed and tested in the present work as a robust cathode catalyst for microbial fuel cells (MFCs). Due to the well-arranged mesopores, the high ... -
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 ... -
Single-atom catalysis for zinc-air/O2 batteries, water electrolyzers and fuel cells applications
(2022)We summarize the latest progress achieved in precious and non-precious carbon based single-atom catalytic active sites, including Pd, Pt, Ir, Ru, Rh, Au, Fe, Co, Mn, Zn, Sn, and Cu, aiming at facilitating metal-air/O2 ... -
Theoretical modeling of the gas humidification effect on the characteristics of proton ceramic fuel cells
(2019)Proton ceramic fuel cells are promising electrochemical converters that produce electrical energy by oxidizing hydrogen. Understanding the impact of gas humidification on the characteristics of such fuel cells is pivotal ... -
Understanding the electrocatalytic activity of PtxSny in direct ethanol fuel cells
(2011)In the present work, the activity of PtxSny/C catalysts towards ethanol, acetaldehyde and acetic acid electrooxidation reactions is investigated for each one separately by means of cyclic voltammetry. To this purpose, a ...
