Compared to hydrogen fed fuel cells, direct alcohol fuel cells (DAFC) have the advantage of easier system design and operation [1].
Improving the CO tolerance of Pt-based catalysts is very meaningful for the application in proton exchange membrane fuel cells and direct alcohol fuel cells.
Then when alcoholic rats take alcohol, the cells become more fluid, moving to zero instead of minus two as might be the effect of alcohol on the cells of nonalcoholic rats.
This prepared Pd-Au-Ag(1 1 1)/RGO catalyst should have great potential for use in direct alcohol fuel cell.
Ethanol has been recognized as the ideal fuel for direct alcohol fuel cell (DAFC) systems due to its high energy density, non-toxicity and its bio-generation.
The electro-catalysts are characterized using XRD, SEM-EDX, ICP-OES, TEM, Cyclic Voltammetry (CV), Choronoamperometry (CA), Electrochemical Impedance Spectroscopy (EIS) and direct alcohol fuel cell test (DAFC).
The mechanism(s) by which alcohol causes cell injury are still not clear but a major mechanism appears to be the role of lipid peroxidation and oxidative stress in alcohol toxicity.
As the PEM porous substrate is wetted and imbibed well by the methanol compared to ethanol, it is expected that the cross over of methanol would be higher than that of ethanol in direct alcohol fuel cell.
This metal presents high overpotentials for the oxidation of organic compounds and the poisoning of active sites by strongly adsorbed intermediates, mainly CO, which decrease the efficiency of a direct alcohol fuel cell (DAFC).
The development of an internal reforming alcohol fuel cell (IRAFC) poses an ambitious technological and research challenge, which requires the effective combination of various technological approaches as regards materials development, chemical reaction engineering and stack design.
