Methanol tolerant electrocatalysts for the oxygen reduction reaction
Direct methanol fuel cells (DMFCs) represent an interesting alternative in obtaining electricity in a clean and efficient way. Portable power sources are one of the most promising applications of passive DMFCs. One of the ...
Effect of water content in the gas diffusion layer of H2 O2 PEM fuel cell
(Journal of Materials Science and Engineering, 2016)
The heart of a fuel cell is the membrane-electrode assembly consisting of two porous electrodes, where the electrochemical reactions take place, and the ionomer conductive membrane, which allows the proton exchange from ...
Searching for suitable catalysts for a passive direct methanol fuel cell cathode
Trimetallic PtMRu/C cathode catalysts with M ¼ Co or Fe obtained by an impregnation procedure using ethylene glycol and NaBH4 as reducing agent, with suitable activity for the oxygen reduction reaction (ORR) and improved ...
Research on methanol tolerant catalysts for the oxygen reduction reaction
Direct methanol fuel cells (DMFCs) generate electricity in a clean and efficient way, so they are a valuable alternative to traditional environmentally harmful technologies. Portable power sources are one of the applications ...
Síntesis de nano catalizadores para celdas de combustible de metanol directo
(Revista Tecnología y Ciencia UTN, 2014)
Las celdas de combustible de metano/ directo, DMFCs, permiten una conversión completa de la energía de la reacción química (CH)3OH(ac)+3/2 O2(g)=7CO2(g)+2H2O(l) en energía eléctrica. El platino es el catalizador más utilizado ...
Preparation and evaluation of carbon supported catalysts for ethanol oxidation
Supported PtSnIr/C, PtSn/C, and IrSn/C catalysts with potential application in a direct alcohol fuel cell were prepared by chemical reduction employing Pechini methodology. The catalyst particles were characterized by ...
