Acidic or alkaline direct ethanol fuel cells (DEFCs) can be a sustainable alternative for power generation if they are fuelled with bio-ethanol. However, in order to keep the fuel cheap, ethanol has to be exempted from tax on spirits by denaturing. I

PdRh/C is a highly active electrocatalyst for methanol oxidation reaction in alkaline media. In this study, the methanol oxidation at PdRh/C was investigated electrochemically in half-cell experiments for various temperatures and various methanol con

The electrochemical oxidation of methanol on electrocatalysts is intensively investigated since direct methanol fuel cells (DMFCs) were proposed as a promising alternative as power source for mobile and back-up power applications. In DMFCs, methanol
The oxygen reduction reaction (ORR) mechanism for electrochemical production of hydrogen peroxide is investigated for an Au-Pd catalyst with 25 at% palladium. The sample was prepared by chemical reduction of a precursor solution on a carbon-based sub

Recently, the use of alkaline anion exchange membranes has yielded some enhancement of direct ethanol fuel cells at least with respect to the achieved performances. However, so far reports have been made for cells operated with a large excess of KOH

An ethanol derivative and fusel oil were investigated regarding their possible use as denaturing agents for ethanol for DEFC in 0.5 M sulphuric acid and 0.1 M potassium hydroxide solution at platinum by means of cyclic voltammetry and differential el

In the framework of a project funded by the Fraunhofer Gesellschaft, a direct ethanol fuel cell has been developed. As part of the development, a new catalyst concept for the anodic oxidation of ethanol at an increased CO2 efficiency by using two dif

In order to be tax free, the ethanol for use in direct ethanol fuel cells (DEFC) needs to be denatured. The electrochemical behavior of a number of potential denaturing agents was therefore studied with respect to their compatibility with DEFC operat
