Recently, increasingly attentions have been paid to the electro-oxidation of ethanol in alkaline media in the context of using ethanol as a fuel in anion-exchange membrane fuel cell. Alkaline media presents several advantages compared to acidic media. It has been found that the electrocatalytic activity for etanol oxidation in alkaline media is much higher than that in acidic media [1]. Further...

A membrane or an electrode binder to be used in a Solid Alkaline Fuel Cell (SAFC) needs to (i) be insoluble in both aqueous solutions and in the required fuels, and (ii) ha l-0 03 79 23 0, v er si on 1 28 A pr 2 00 9 Author manuscript, published in "J Polym Sci Part A: Polym Chem 47 (2009) 2043-2058" DOI : 10.1002/pola.23290

in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...

High-Performance Alkaline Direct Methanol Fuel Cell using a Nitrogen-Postdoped Anode Report Title A commercial PtRu/C catalyst postdoped with nitrogen demonstrates a significantly higher performance (?10–20?% improvement) in the anode of an alkaline direct methanol fuel cell than an unmodified commercial PtRu/C catalyst control. The enhanced performance shown herein is attributed at least parti...

In the present study, the operating conditions of an anode-supported high temperature direct internal reforming (DIR) planar solid oxide fuel cell (SOFC) are numerically analyzed. SOFCs are the energy conversion devices that produce electricity and heat directly from a gaseous fuel by the electrochemical combination of that fuel with an oxidant. A planar SOFC consists of an interconnect structu...

1.1 Background Thanks to the breakthroughs in microfabrication technologies, numerous concepts of microsystems including micro aerial vehicles, microbots, and nanosatellites have been proposed. Contrary to ordinary electronic devices, these microsystems perform mechanical work and require the extended operation. As their functions are getting complex and advanced, their energy consumption is al...
