A high selectivity quaternized polysulfone membrane for alkaline direct methanol fuel cells
(Elsevier Science, 2015-02)
Alkaline membranes based on quaternized poly(arylene ether sulfone) (QPAES) were characterized in relation to their water and methanol uptake, methanol permeability, electrical conductivity, and mechanicalproperties. The ...
Research on methanol-tolerant catalysts for the oxygen reduction reaction
(Springer, 2015-06)
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 ...
Methanol/air fuel cells: catalytic aspects and experimental diagnostics
(Pergamon-Elsevier Science Ltd, 2008-07)
Methanol/air fuel cell with direct feed of methanol has received growing attention due to the possibility of using a liquid fuel of simple storing. This work comments studies on the preparation of PtRu catalysts for methanol ...

Effect of bimodal mesoporous carbon as PtRu catalyst support for direct methanol fuel cells
(Royal Society of Chemistry, 2020-08)
Mesoporous carbons (MCs) with different pore sizes were synthesized and evaluated as a catalyst support for fuel cells. The MCs were obtained from resorcinol-formaldehyde precursors, polymerized in the presence of ...
High-activity mesoporous Pt/Ru catalysts for methanol oxidation
(American Chemical Society, 2013-10)
High activity mesoporous Pt/Ru catalysts with 2D-hexagonal structure were synthesized using a triblock poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) copolymer (Pluronic F127) template. The normalized ...
