V-Shaped sandwich-type cell with reticulate electodes
First Claim
1. An electrolytic cell for the electrolysis of aqueous solutions to produce gaseous products which comprises a housing, a separator traversing said housing to form an anode compartment and a cathode compartment, an anode in said anode compartment adjacent to said separator, a cathode in said cathode compartment adjacent to said separator, means for introducing an electrolyte into and removing said electrolyte from said anode compartment, an outlet for gaseous products in said anode compartment, means for introducing a liquid into and removing a liquid from said cathode compartment, an outlet for gaseous products in said cathode compartment, means for supplying electrical current to said anode and said cathode, at least one of said anode and said cathode comprising a porous electrode having a porosity in the range of from about 30 to about 98 percent, said porous electrode having a first portion in direct contact with said separator and a second portion spaced apart by an angle of inclination from said separator, said second portion being closer to said outlets for gaseous products than said first portion.

Abstract
An electrolytic cell for the electrolysis of aqueous solutions to produce gaseous products is comprised of a housing, a separator traversing said housing to form an anode compartment and a cathode compartment, an anode in the anode compartment, a cathode in the cathode compartment, means for introducing an electrolyte into and removing said electrolyte from said anode compartment, an outlet for gaseous products in the anode compartment, means for introducing a liquid into and removing a liquid from the cathode compartment, and an outlet for gaseous products in the cathode compartment. The electrolytic cell has at least one of the anode and the cathode comprising a porous electrode having a porosity in the range of from about 30 to about 98 percent, the porous electrode having a first portion in direct contact with the separator and a second portion spaced apart from the separator, the second portion being closer to said outlets for gaseous products than said first portion.
The electrolytic cell operates at reduced cell voltages with improved release of gas bubbles formed during electrolysis and improved liquid circulation through the porous electrode.
