| 摘要 |
<p>The invention refers to a fuel cell electrode for oxidation of preferably methanol in a fuel cell with acid electrolyte. The electrocatalytically active material comprises known noble metal catalysts such as mixtures of platinum and ruthenium which have been fortified with lead or lead compounds added in this connection in a large quantity so that the addidtion of lead or lead compounds is above a concentration around 1 mg Pb/cm2. A suitable amount is 5-10mg Pb/cm2. Fuel cell electrodes of this kind can also be used for other fuels for instance hydrogen containing carbon monixide in acid electrolytes up to around 250°C.</p> |
