Abstract
The present invention relates to an immersible gaseous oxidant cathode for an electrochemical cell system. The electrochemical cell system is configured to utilize an oxidant reduction electrode module containing an oxidant reduction electrode mounted to a housing to form a gaseous oxidant space therein that is immersed into the ionically conductive medium. A fuel electrode is spaced from the oxidant reduction electrode, such that the ionically conductive medium may conduct ions between the fuel and oxidant reduction electrodes to support electrochemical reactions at the fuel and oxidant reduction electrodes. A gaseous oxidant channel extending through the gaseous oxidant space provides a supply of oxidant to the oxidant reduction electrode, such that the fuel electrode and the oxidant reduction electrode are configured to, during discharge, oxidize the metal fuel at the fuel electrode and reduce the oxidant at the oxidant reduction electrode, to generate a discharge potential difference therebetween for application to a load.

The completed cell module 690 that comprises ionic conduction medium module 450, battery component 290a and 290b and circuit module 640 has thereon been described in Figure 17.In certain embodiments, the ionic conduction medium that usually will flow to fluid intake 480 and effluent fluid outlet 490 is kept in holder R (not shown), and stream pump FP (also not shown) can be used to carry out pumping by 690 pairs of ionic conduction media of one or more battery modules.In certain embodiments, a plurality of fluid intakes 480 can by manifold connect and each other fluid ground be connected, but so that the stream of stream pump FP parallel drive by each battery module 690.(be head remain in outlet disperser chamber 520 and thus in the situation that flow export 490 places) in other embodiments, can be connected with the inflow entrance 480 fluid ground of battery module 690 subsequently at the flow export 490 of front battery module 690, so that the ionic conduction medium flows through each battery module 690 serially from reservoir R.In certain embodiments, battery module 690 can crossfire with and the combination of stream and fluid ground is connected.In certain embodiments, each battery module 690 can comprise its oneself stream pump FP.In certain embodiments, each battery module 690 can be configured to make its dielectric supply of ion guide that oneself arranges circulation more therein, and flow export 490 can directly lead in stream pump FP thus, directly the logical flow export 480 of same battery module 690 of getting back to.
In certain embodiments, one or more oxidant inlet connectors 670 can be connected with oxidizer source.Although oxidizer source can be the surrounding environment gaseous oxidizer in certain embodiments, can provide in other embodiments gaseous oxidizer pump AP to flow through gaseous oxidizer path defined in the oxidant reducing electrode module 10 to set up gaseous oxidizer or other oxidants.As the liquid path that comes self-flow pump FP, the gaseous oxidizer path of gaseous oxidizer pump AP can be connected in series or in parallel with oxidant reducing electrode connector 670.In certain embodiments, within one or more gaseous oxidizer pump AP can be embedded in circuit module 640, and can draw gaseous oxidizer by oxidant inlet connector 670 and be drawn to outside oxidant outlet connector 680.In certain embodiments, one or more gaseous oxidizer pump AP can be positioned at along the gaseous oxidizer path Anywhere, and can by gaseous oxidizer is drawn or push away to set up gaseous oxidizer or other oxidants flow to set up stream.Gaseous oxidizer pump AP can be any appropriate configuration or configuration, including, but not limited to axial fan, centrifugal blower, crossflow blower fan or so-called " on-bladed blower fan ".
By disperser gaseous oxidizer entrance 500, gaseous oxidizer is offered the gaseous oxidizer disperser in addition for the identical gaseous oxidizer pump AP that oxidant is offered oxidant reducing electrode module 10 in certain embodiments.In other embodiments, the disperser gaseous oxidizer pump DAP (also not shown) that separates with gaseous oxidizer pump AP offers disperser gaseous oxidizer entrance 500 with gaseous oxidizer, and described gaseous oxidizer is under than the higher pressure of the gaseous oxidizer that offers oxidant reducing electrode module 10 in certain embodiments.For example, gaseous oxidizer pump AP can provide the increase of the pressure of the about 1/4PSI on the atmospheric pressure of side 45 to the oxidant of oxidant reducing electrode 20 in an embodiment, this can provide the power perpendicular with oxidant reducing electrode 20, and it especially can help the ionic conduction medium of oxidant reducing electrode 20 is carried out balance towards the dielectric power of ion guide on side 40.Similarly, disperser gaseous oxidizer pump DAP can be provided to the increase of the pressure of the about 1/2PSI on atmospheric pressure in disperser gaseous oxidizer entrance 500 in an embodiment, after this provides it at least entrance disperser chamber 510 (and offer in certain embodiments outlet disperser chamber 520).The pressure that gaseous oxidizer pump AP and/or disperser gaseous oxidizer pump DAP provide is different because of embodiment, and therefore can use any suitable pressurization (if at all having).
The oxidizer source of oxidant reducing electrode module 10 can be the source (such as for example oxygen tank) of (contained) oxidant of control in certain embodiments.In an embodiment, making can recirculation from the oxygen of electrochemical cell, such as disclosed in U.S. Patent application 12/549,617 and by with reference to its integral body is combined in this.Similarly, when oxidant was oxygen from the surrounding environment gaseous oxidizer, oxidizer source can be thought transfer mechanism widely, and no matter be passive or initiatively (for example, pump, air blast etc.), can allow oxidizer source to flow to oxidant reducing electrode 20 by this.Therefore, term " oxidizer source " intention comprises for being sent to from the oxygen of surrounding environment gaseous oxidizer oxidant and/or the arrangement of the control of oxidant reducing electrode 20 passively or on one's own initiative.
In various embodiments, oxidant reducing electrode module 10 be configured to and from the aligning of fuel electrode module 160 can be different with the explanation here.For example, oxidant reducing electrode module 10 can comprise a pair of relative oxidant reducing electrode 20 in certain embodiments, and this is configured to be aligned between a pair of relative fuel electrode 170 to relative oxidant reducing electrode 20.In some this embodiment, baffle plate 158 can be from the top section 60 of module 30 and base section 90 extend to the gaseous oxidizer space, the a pair of mounting panel 50 of wherein placing oxidant reducing electrode module 10 surrounds baffle plate 158, to limit the gaseous oxidizer passage of the outlet 130 from gaseous oxidizer entrance 120 to gaseous oxidizer, this gaseous oxidizer passage can make gaseous oxidizer contact with two oxidant reducing electrodes 20.In certain embodiments, the fuel electrode that separates by the oxidant reducing electrode module 10 that has therein a pair of oxidant reducing electrode 20 can share ionic conduction medium (being that oxidant reducing electrode module 10 and two fuel electrodes 20 are dipped in the same ion conducting medium) to 170.Similarly, as mentioned above, in fuel electrode 170 one or both can be coupled with oxidant reducing electrode module 10.In certain embodiments, a pair of oxidant reducing electrode module 10 can be surrounded common fuel electrode 170 between it or the fuel electrode 170 of a pair of link between it, and with at U.S. Patent Application Serial Number No.13/362, described in 775 and by this those are similar can form double cell in certain embodiments with reference to being combined in.
As noted above, in certain embodiments the baffle plate within air space 158 or other supporting constructions can be usually by providing common rigidity supporting structure to promote alleviating of the power of liquid ions conducting medium on oxidant reducing electrode 20 or other distributions for the oxidant reducing electrode 20 in the gaseous oxidizer space.The material stiffness than shell 30 is less usually can to will be appreciated that the material that is assembled in oxidant reducing electrode 20, and thereby has tendency in the gaseous oxidizer space that is bent between baffle plate 158 in being immersed in the ionic conduction medium time under the dielectric fluid pressure of ion guide.This bending can have many side effects, including, but not limited to tension force being placed in on the adhesive that oxidant reducing electrode 20 is fixed to installation frame 50 and make electrical field deformation between oxidant reducing electrode 20 and fuel electrode 170.Therefore, can will be appreciated that baffle plate 158 can be arranged in the gaseous oxidizer space in order to support the zone of oxidant reducing electrode 20 with the trend of reduction oxidant reducing electrode 20 bendings under fluid force.
For example, Figure 18 shows the embodiment of oxidant reducing electrode module 10, and its common fine and close arrangement that baffle plate 158 has been described is flow through this air duct with steering current AF in order to the air duct that is limited between it is narrowed down on the illustrated direction of arrow.Utilize this fine and close arrangement of baffle plate 158, due to larger support being provided, oxidant reducing electrode 20 otherwise the zone that can bend under fluid force have reduced.In addition, can will be appreciated that baffle plate 158 itself can be enough thick so that for oxidant reducing electrode 20 provides further support, as described in more detail below in an embodiment.In certain embodiments, the thickness of baffle plate 158 and between the interval can be proportional to one another in order to make the support of oxidant reducing electrode 20 is maximized, also make simultaneously the air-flow by air duct maximize and make oxidant reducing electrode 20 be exposed to air or other gaseous oxidizers.
Although be not restriction, in the explanation embodiment of Figure 18, the thickness x of baffle plate 158 can be approximately 1mm on Width.In addition, in the illustrated embodiment, the interval y between baffle plate 158 can be approximately 2mm on Width.In other embodiments, thickness x and interval y can change and can depend on the relative rigidity of oxidant reducing electrode 20.For example, in the situation that oxidant reducing electrode 20 has common rigidity or strengthens character, can utilize the more wide interval y of baffle plate 158.As example, in certain embodiments, the interval y of baffle plate 158 can be greatly between 1-50mm, such as being approximately 20mm in an embodiment, approximately being 10mm or being approximately 5mm.Similarly, in certain embodiments the thickness x of baffle plate 158 can be greatly about 0.5 and 10mm between, such as being approximately 5mm in an embodiment or being approximately 2mm.
Figure 19 has described the perspective cross-sectional view of dwindling of the regional XVIII that highlights in the embodiment of Figure 18.Again, baffle plate 158 can be configured to make air-flow AF to separate different direction (namely in passing through the air duct of oxidant reducing electrode module 10).As what can recognize in the view of Figure 19, can be by making the hydrostatic pressure of coming on the contrary the equilibrium ion conducting medium that oxidant reducing electrode 20 (transparent illustrate to illustrate with baffle plate 158 contact) is applied from the ionic conduction medium power of passing baffle plate 158 of the rear portion 100 of shell 30.Thereby, the ionic conduction medium that enters oxidant reducing electrode 20 can be pressed onto the oxidant of oxidant reducing electrode 20 supporting zone 700 towards side 45 in the contact-making surface 710 of baffle plate 158 towards the ionic conduction medium power of side 40, and itself receives from the dielectric relative ionic conduction medium power of the ion guide among the rear portion 100 that is pressed onto shell 30.Therefore, can offset ionic conduction medium power by the length of baffle plate 158, among the air duct that this restriction oxidant reducing electrode 20 is deformed in those supporting zones 700.In addition, the effect of reduction hydrostatic pressure can prevent that electrolyte from passing through the speed increase that oxidant reducing electrode 20 flows out.Adhesive such as PTFE may can little by little change pore size under pressure, described pressure otherwise can make air space that the ionic conduction medium flows out to oxidant reducing electrode module with to the air duct between baffle plate 158.Therefore, by reducing the effect of hydrostatic pressure, the useful life that can improve oxidant reducing electrode 20.
Again, the restriction that makes interval y between baffle plate 158 have a certain size so that baffle plate 158 provides across the oxidant of oxidant reducing electrode 20 towards enough supports of side 45 or prevent the distortion (namely as described, in unsupported regional 720) of the oxidant reducing electrode 20 between adjacent contact face 710.Yet, although can will be appreciated that baffle plate 158 can be formed by the dense material structure in certain embodiments, but can be common breathable in the part of the baffle plate 158 of contact-making surface 710 near-ends itself at least in other embodiments, in order to promote to absorb the gaseous oxidizer at those supporting zones 700 places of oxidant reducing electrode 20.Similarly, to such an extent as to the oxidant of oxidant reducing electrode 20 enters into oxidant reducing electrode 20 oxidant is offered supporting zone 700 towards side 45 is enough ventilative with the contacted oxidant of supporting zone 720 not in certain embodiments.
