Abstract
The subject invention relates to an electrochemical cell in which a fiber containing electrode, a membrane separator, the electrolyte, the second electrode or electrocatalyst of the second electrode complete an electrochemical cell. Further, to a process for fabricating a fiber cell in which the cell is completed by two fibers, one containing, an electrode, a membrane separator, the electrolyte, and the other a second electrode. The two electrodes represent the positive and negative electrodes of an electrochemical cell.
Claims17
An electrochemical cell comprising 1) porous, fibrous, membrane separator, where the length of the membrane fiber extends longer as compared to the fiber diameter, said membrane separator having a bore side, shell side and lumen, 2) an electrolyte disposed in the pores of said membrane separator, 3) electrically conductive fibers in contact or covered with an electrocatalyst forming positive and negative electrodes, 4) at least one food inlet to said electrodes, 5) at least one feed outlet from said electrodes,
- said electrodes comprising an inner electrode, formed from an electrically conductive fiber in contact or covered with an electrocatalyst and housed within the bore of said membrane separator, said housing having a lumen, allowing free passage of liquid or gaseous feed components through the bore side and to the inner electrode, or,
- formed from coating or impregnating an electrocatlyst material on the shell side of a second inner hollow, fibrous, porous separator with fibrous current collectors in contact with the shell side of the inner hollow, fibrous, separator, said electrode housed within the bore of the first hollow fibrous membrane separator, wherein the lumen of the inner hollow, fibrous separator allows for free passage of liquid and gaseous feed components to the inner electrode, or,
- formed from an inner hollow, fibrous, porous separator with distinct fibrous electrodes in contact with the shell side of said inner hollow, fibrous separator, wherein the distinct fibrous electrodes are formed from an electrically conductive fiber covered or in contact with an electrocatalyst material, said electrodes housed within said bore of the first hollow, fibrous, membrane separator, wherein the lumen of the inner hollow, fibrous separator allows for free passage of liquid and gaseous feed components to the inner electrode,
- and said electrodes further comprising an outer electrode, said outer electrode comprising,
- a coating of electrocatalyst material and an electrically conductive material surrounding or impregnating the shell side of said membrane separator, or,
- electrically conductive fibers covered or in contact with a positive or negative elecrocatalyst material surrounding said membrane separator.
