Verfahren zur Herstellung einer porösen Metallelektrode für galvanische Zellen

摘要

A porous metal electrode for an electro-chemical cell is produced by casting an alloy of electrode-forming metal and a second metal having a lower boiling or sublimation point, solidifying the alloy in the mould by cooling from one side only and removing the second metal by evaporation or sublimation to give an electrode having interconnected pores.
