Rhodium effects on Pt anode materials in a direct alkaline ethanol fuel cell

Pt based anode catalysts for direct ethanol fuel cells

In the present work several Pt-based anode catalysts supported on carbon XC-72R were prepared with a novel method and characterized by means of XRD, TEM and XPS analysis. It was found that all these catalysts are consisted of uniform nanosized particles with sharp distribution and Pt lattice parameter decreases with the addition of Ru or Pd and increases with the addition of Sn or W. Cyclic vol...

Performance of an alkaline-acid direct chloro ethanol fuel cell

This paper reports on the performance of an alkaline-acid direct chloro ethanol fuel cell (AA-DCLEFC) that is composed of an alkaline anode, a membrane and an acid cathode. The effects of membrane thickness and the concentration of various species at both the anode and cathode on the cell performances are investigated. It has been demonstrated that the peak power density of this AA-DCLEFC that ...

High-performance alkaline direct methanol fuel cell using a nitrogen-postdoped anode.

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 partially to the increased electrochemical surface area of the PtRu/C after postdoping with nitrogen.
