Abstract
A process for operating an electrolytic cell having a relatively-massive dual porosity gas electrode particularly well suited and adapted for utilization as a vertically-disposed oxygen gas-bearing electrochemically reducing cathode in electrolytic cells wherein, for efficient and practical, commercially-large-scale-output operations, there are required to be employed substantial electrolyte liquid depths creating considerable head pressures generally greater than at least about 1 psi (ca. 0.69 dynes/cm.sup.2) is comprised of distinct juxtaposed, contiguous, yet separate, diversely porous electrode body wall members or layer sections, one of which for immediate electrolyte contact and handling is of relatively finer pored structure and the other of which for immediate gas contact and handling is of relatively larger or coarse pored structure; the electrode being so embodied and characterizable for given application as to have a bubble point pressure that is larger than the summation of the hydraulic head pressure and the liquid capillary pressure in the coarse pore layer.
