Liquid fuel cells
The advantages of liquid fuel cells (LFCs) over conventional hydrogen-oxygen fuel cells include a higher theoretical energy density and efficiency, a more convenient handling of the streams, and enhanced safety. This review focuses on the use of different types of organic fuels as an anode material for LFCs. An overview of the current state of the art and recent trends in the development of LFC...
متن کاملLiquid methanol concentration sensors for direct methanol fuel cells
Liquid-fed direct methanol fuel cells (DMFCs) are one of the most promising candidates for portable power electronics and automotive pplications due to their potentially high-energy density, simple storage, and distribution of the fuel. The concentration of methanol in the fuel irculation loop of a DMFC system is an important operating parameter, because it determines the electrical performance...
متن کاملanalysis of liquid - fuel vortex
for a long time, many efforts have been taken on improving gas turbine performance to increase the propulsive force and keep the chamber walls cool. in this regard, implementation of cyclonic and vortex engines have been proposed. according to increasing in the engine efficiency and keeping the chamber walls cool, the bidirectional vortex flow which is exited in the vortex engine, makes researc...
متن کاملSynthesis of Sulfonated Polystyrene/acrylate–ionic Liquid (Si-SPS/A–IL) Hybrid Membranes for Methanol Fuel Cells
In this paper, the silicon-containing sulfonated polystyrene/acrylate–ionic liquid (Si-SPS/A–IL)hybrid membranes was prepared to obtain the proton exchange membrane (PEM) materials withhigh methanol barrier and good selectivity. The Si-SPS/A–IL hybrid membranes characterized asthe function of IL to evaluate their potential as PEMs in direct methanol fuel cells (DMFCs).Fourdifferent Hybrid mater...
متن کاملAdvances in Desulfurization Research of Liquid Fuel
The new requirements for sulfur content in liquid fuels demand the use of novel deep desulfurization processes. 4-methyldibenzothiophene, 4,6dimethyldibenzothiophene and their alkyl-substituted derivatives are the key substances that need to be separated from diesel fuel and fuel oil. These compounds require higher hydrogen consumption in the hydrodesulfurization process and the use of addition...
