Abstract
Si descrive un procedimento per produrre un elettrodo a gas, comprendente la calcinazione di una miscela di una polvere di carbone e di una polvere di resina al fluoro per formare un foglio come base di un elettrodo a gas, il rivestimento di un solo lato della base in foglio con una soluzione organica preparata sciogliendo un sale di metallo del gruppo del platino in un solvente organico capace di formare un complesso organico con il sale metallico, l'essiccamento dello strato di rivestimento ad una calcinazione dello strato di rivestimento ad una temperatura da 250° a 380°C in una atmosfera inerte, per ridurre l'ossido di metallo del gruppo del platino formando con ciò uno strato di catalizzatore sulla base in foglio. La riduzione (calcinazione) del sale di metallo del gruppo del platino può essere eseguita senza usare il pericoloso idrogeno gassoso e senza concomitanza della decomposizione della resina al fluoro, fornendo con ciò uno strato uniforme di catalizzatore comprendente particelle fini di platino aventi una grande area superficiale con spessore minimizzato.
