| 摘要 |
<p>The invention provides electrodes for water electrolyzers that (a) are cheaper than electrodes composed wholly of sintered particles and (b) give as good, or lower overpotentials in tho release of gases as the said electrodes. The electrodes according to the invention have an impervious, electrically conductive substrate and, bonded to the substrate, a porous metallurgically bonded layer from 25 to 275 mu m thick made of nickel, nickel-iron alloy, iron or iron-carbon alloy particles having a diameter of 2 to 30 mu m that are sintered to a theoretical density of from 45 to 60%. </p> |
