摘要
The present invention provides a cathode that has a conductive substrate and a catalyst layer formed on the conductive substrate. The catalyst layer comprises a first layer and a second layer. The first layer at least includes palladium element and platinum element. The second layer at least includes iridium element and platinum element. The first layer is located on the conductive substrate, and the second layer is located on the first layer. The cathode is useful because it has a low hydrogen overvoltage and degradation and peel-off of the catalysis layer is reduced against reverse current generated when electrolysis is stopped.
