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 ...
Searching for suitable catalysts for a passive direct methanol fuel cell cathode
(Pergamon-Elsevier Science Ltd, 2015-12)
Trimetallic PtMRu/C cathode catalysts with M = 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 ...
Methanol tolerant electrocatalysts for the oxygen reduction reaction
(Springer, 2014-09-18)
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 ...
Oxygen Reduction on Methanol-Tolerant Carbon-Supported PtxSy Nanoparticles Prepared by a Single-Step Low-Temperature Method
(Springer, 2019-09-01)
In direct methanol fuel cells (DMFCs), the methanol crossover from the anode to the cathode is a major cause of power density loss because of the overpotential arising due to the parasitic reaction of methanol oxidation ...
Oxygen reduction activity and methanol tolerance of carbon-supported PtV nanoparticles and the effects of heat treatment at low temperatures
(2016-04-01)
This paper reports on oxygen reduction activity and methanol tolerance of PtV/C prepared by a polyol method and the effects of heat treatments in reducing environments at low temperatures (up to 300 °C). The as-prepared ...
Methanol tolerant electrocatalysts for the oxygen reduction reaction
(Springer, 2017)
Oxygen reduction on PtFe/C electrocatalysts prepared in microemulsions
(2008-12-22)
PtFe/C nanocatalysts of different compositions and nearly constant particle size were prepared by a microemulsion method. Crystallite sizes and degree of alloying were determined by X-ray diffraction. Particle size and ...
