Abstract

Une électrode réductrice d'oxygène possède un substrat en carbon à faible teneur en cendres, tel que des coquilles de noix de coco converties en charbon. Le substrat est chargé avec un catalyseur tel que i) de la phtalocyanine de platine ou ii) de l'oxyde de plomb-ruthénium. Dans ce deuxième cas (ii), afin de produire l'électrode, des ions plomb sont adsorbés sur le substrat, qui est ensuite traité avec une solution d'oxyde de ruthénium (VI), pour provoquer la précipitation du catalyseur sur le substrat.An oxygen reducing electrode has a low ash carbon substrate, such as coconut shells converted to carbon. The substrate is loaded with a catalyst such as i) platinum phthalocyanine or ii) lead-ruthenium oxide. In this second case (ii), in order to produce the electrode, lead ions are adsorbed on the substrate, which is then treated with a solution of ruthenium oxide (VI), to cause precipitation of the catalyst on the substrate.
