Evaluation of Ethanol, 1‐Propanol, and 2‐Propanol in a Direct Oxidation Polymer‐Electrolyte Fuel Cell: A Real‐Time Mass Spectrometry Study
Open accessAbstract
Ethanol, 1‐propanol, and 2‐propanol have been evaluated as alternative fuels for direct methanol/oxygen fuel cells. The relative product distributions for the electro‐oxidation of these alcohols under fuel‐cell conditions were determined using on‐line mass spectrometry. For water/ethanol mole ratios between 5 and 2, ethanal is the main product, while is a minor product. However, an increase of the water/ethanol mole ratio increased the relative product distribution of slightly. Propanal was the main product of the electro‐oxidation of 1‐propanol with a similar percentage of being formed as for ethanol. In contrast, the electro‐oxidation of 2‐propanol yielded practically only acetone. Between 150 and 190°C, the product distributions for the electro‐oxidation of ethanol, 1‐propanol, and 2‐propanol do not depend significantly on the temperature. No differences in the product selectivities of Pt‐Ru and Pt‐black were found. Ethanol is a promising alternative fuel for direct methanol fuel cells (DMFCs) with an electrochemical activity comparable to that of methanol. Conversely, 1‐propanol and 2‐propanol are not suitable as fuels for DMFCs due to their low electrochemical activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
