  • a fluid flow path 110a is included on the first electrolysis product generating side 108a and another flow path 1 10b is provided on the second electrolysis product generating side 108b, where the respective flow pathway receives the fluid flow from water or other electrolysis fluid into the pores or apertures and has an outlet fluidly coupled to a corresponding separator 112a, 112b.
  • This allows for water or other fluid to flow through the pores or apertures and into the corresponding fluid flow path, and the water or other electrolysis fluid will carry the generated electrolysis products (e.g., oxygen or hydrogen), depending on the side of the electrode.
  • First electrolysis product e.g., hydrogen

  • Reactant water enters pores of electrode side 108b (i.e., the anode) on the exterior of the electrode 108, passing into the interior of electrode 108 to product fluid pathway 110b, where it then flows out of electrode 108 for collection and separation of purified product.
  • the method may comprise separating purified first electrolysis product, purified second electrolysis product, or both from the pumped electrolysis fluid and collecting the purified first electrolysis product, purified second electrolysis product, or both.
  • Flow along electrode side 108a i.e., the cathode
  • Generation of the hydrogen and oxygen products may occur at the electrically charged surfaces within porous anode and porous cathode 108b, 108a, respectively of electrode 108, and product gases are quickly drawn away through the pores or apertures and into the corresponding fluid pathway 110a, 110b of electrode 108. While flow arrows are only shown on anode side 108b of electrode 108 of Figure 3B, it will be understood that flow also occurs on the opposite cathode side 108a of bi-polar plate electrode 108, where the other product gas is generated and collected. Electrolysis occurs while the water travels through the aperture or pore and into the product fluid pathway 110a, 110b, so that material within the product fluid flow path 110a, 110b includes a mix of water and the respective product gas (i.e., hydrogen or oxygen).

  • Figure 3AA shows a configuration similar to Figure 3A, but in which the pores or apertures of the cathode 108a and anode 108b are disposed at a distal end of the cathode 108a and/or anode 108b, away from the water inlet (e.g., adjacent bottom end 124).
  • fluid may enter and exit on opposite faces of the electrode surface (e.g., water enters at exterior surface along anode 108b, and exits from interior fluid flow pathway 110b).
  • the fluid may enter and exit generally along the same axis as electrical current flow.
  • No membrane is required in order to separate oxygen and hydrogen gaseous products. Gases are separated by an electrically conducting plate 114, not ionically with the aid of a membrane.
  • An electrically conductive path is provided through electrode 108 from one surface defining the side of the fluid flow path (e.g., 110b) to the other surface defining the other side of the fluid flow path (e.g., 110b), so that electrical conduction is not required to be through the electrolyte solution (and the generated gas bubbles). This is possible because the pores or apertures allow a hard metal electrically conductive connection to be made (e.g., through jumpers 116).
  • the system 100 eliminates the need for a membrane as fluid flow takes the generated gas bubbles through the fluid paths 110a, 110b into separators 112a, 112b.
  • the fluid flow also decreases the amount of bubbles in the ion conducting path because as the bubbles are formed, they are removed by the flow of water into the fluid flow path (e.g., 110a, 110b) and downstream to the separators 112a, 112b.
  • This process increases the efficiency and capacity of the individual electrodes and the electrolysis system as a whole (e.g., systems including multiple electrodes in series or parallel for increased product generation or purity).
  • multiple bi-polar electrode plates may be situated together in a given electrolysis chamber.
  • Such a system may include monopolar plates on either end (e.g., a cathode at one end, and an anode at the opposite end) of such a series of bi-polar plates.
  • Figure 4A shows how traditionally configured electrodes result in the formation of gas bubbles 118 adjacent the electrode surface S, which results in an area of high electrical resistance HR adjacent the electrode surface.
  • Such systems may rely on the formation of an electrical circuit through the electrolyte from one electrode to the other (not shown).
  • the resistance caused by such bubbles, as well as the resistance associated with a large distance of electrolyte separating the electrodes can be responsible for the majority of electrical resistance associated with the circuit.
  • the presently contemplated electrodes 108 provide pores or apertures 120 through the electrode 108b, reducing the formation of bubbles that would provide electrical resistance due to their location.
  • the distance of the electrical circuit going through the electrolyte solution is significantly smaller, so that the vast majority of the circuit (e.g., substantially all) is hard wired through the metal structures of the electrode.
  • Figure 5 illustrates an alternative electrode configuration 208 including a single inlet 204 (e.g., for water), and two types of outlets 211a, 211b.
  • the boundary 208a, 208b between the inlet 204 and the respective outlets 21 la, 21 lb is porous so as to include pores or apertures through which the water can enter, generation of the gaseous products can occur, and one gaseous product (e.g., hydrogen) can be withdrawn from one type of outlet (e.g., 211a), while the other gaseous product (e.g., oxygen) can be withdrawn from the other type of outlet 210b.
  • one gaseous product e.g., hydrogen
  • the other gaseous product e.g., oxygen
  • outlets including a relatively large perimeter outlet (one class), with four smaller outlets (another class) centrally disposed within the central inlet.
  • Electrolysis may occur at the boundary between the inlet 204 and outlets 211a, 21 lb, and within the pores or apertures leading from the inlet 204 to the respective outlet.
  • Hydrogen may be drawn off through small central outlets 211a, while oxygen may be drawn off through the single large perimeter outlet 21 lb.
  • assignments of the outlets relative to the hydrogen and oxygen products may be reversed (e.g., by changing the polarity of the electrodes 208a, 208b).
  • Figure 6 illustrates another similar configuration 308 including an inlet 304 and two outlets 311a, 311b in which the inlet 304 is sandwiched between an outlet 31 la at the center of the system and another outlet 31 lb is provided at the perimeter of the system.
  • the location of gaseous products may be similar to as described above with respect to Figure 5.
  • the boundaries 308a, 308b between inlet 304 and the outlets 311a, 311b are similarly porous, including pores or apertures through which the water and generated gaseous products may flow from the inlet 304, across the electrodes 308a, 308b through pores or apertures, and into a corresponding product fluid pathway outlet 31 la, 31 lb.
