Embodiment
Fig. 1 represents the schematic diagram of an execution mode of bipolar plate.
Bipolar plate shown in Fig. 1 can also be called flow-field plate (flow-fieldplate).Bipolar plate 10 not only may be used for electrolytic cell, and may be used for fuel cell.Bipolar plate 10 especially may be used for PEM battery (ProtonExchangeMembrane proton exchange membrane), and it is often called PEM-heap (protonexchangemembraneStack proton exchange membrane stack).Bipolar plate 10 is also applicable to other and also can be called in the electrochemical assembly of the battery implementing chemical reaction and/or generating.
In bipolar plate 10 and/or form at least one heat pipe 12 (forming a compact unit with this bipolar plate 10 and at least one heat pipe 12) wherein.This at least one heat pipe 12 can be understood as a thermal conductor, and it allows high density of heat flow rate under the heat of evaporation utilizing medium/cooling agent.Therefore a large amount of heats can be carried on of at least one a heat pipe 12 smaller sectional area.Such as, this at least one heat pipe 12 can comprise at least one heat pipe and/or at least one two-phase thermo-siphon.Especially in the embodiment here enumerated, at least one heat pipe 12, the conveying of medium/cooling agent generally in not additional auxiliary plant equipment, such as, can realize under pump (circulating pump).Relative energy-saving is cooled reliably by means of at least one heat pipe 12 with this bipolar plate 10.In addition, when bipolar plate 10 is equipped with at least one heat pipe 12, owing to cancelling pump whereby, such as circulating pump and save cost.
General each bipolar plate 10 can define an active side 14, and it is directed relative to another bipolar plate and/or semipermeable membrane after bipolar plate 10 is arranged in electrolytic cell or fuel cell.Active side 14 can also be explained as reaction pairing side.(side pointed to leaving mutually with other bipolar plate and/or semipermeable membrane after bipolar plate 10 is arranged in electrolytic cell or fuel cell is often called inactive side 16.) in the embodiment of figure 1, bipolar plate 10 has multiple heat pipe 12, they are extended continuously by bipolar plate 10 parallel with active side 14 (and parallel with inactive side 16).As long as this at least one heat pipe 12 is extended by bipolar plate 10 perpendicular to active side 14 (with perpendicular to inactive face 16), the cooling bipolar plate equably 10 of wishing just can be realized.
The number of 5 heat pipes 12 shown in Fig. 1 is only exemplarily explained.The number of the heat pipe 12 of bipolar plate 10 can be selected so simply, makes the Homogeneous cooling realizing bipolar plate 10 by means of at least one heat pipe 12.
Advantageously, () forms at least one serpentine channels 18 except this at least one heat pipe 12 additionally in bipolar plate 10, can guide at least one gaseous state or liquid medium by it.This at least one serpentine channels 18 can also be called at least one snakelike groove.By at least one serpentine channels 18 (or at least one snakelike groove) at least one by means of this electrolytic cell or fuel cell attainable/educt of chemical reaction that realize and/or at least one chemical reaction product can as at least one gaseous state or liquid medium transport or carrying-offs.Such as, oxygen and/or water can be guided by this at least one serpentine channels as at least one gaseous state or liquid medium.This at least one serpentine channels 18 can have at least one raceway groove entrance (educt entrance/product inlet) 20 and/or at least one channel outlets (educt outlet/product exit) 22.
Because bipolar plate 10 is advantageously equipped with at least one heat pipe 12, remove the necessity using at least one gaseous state or liquid medium (it can be guided by least one serpentine channels 18) to cool bipolar plate 10 from.The flowing velocity of the lowest speed of the needs lower than coolant of this at least one medium is just enough thus.Correspondingly can also at least one serpentine channels 18 be formed smaller.
Another advantage that cancellation cools the necessity of bipolar plate 10 by means of the medium that at least one serpentine channels 18 guides is, temperature identical with existence (substantially) on channel outlets 22 on raceway groove entrance 20.Between raceway groove entrance 20 and channel outlets 22, conventionally often there is temperature contrast (reaching 10 degree of Kelvins), this may cause electrolytic cell or fuel cell (such as, PEM-piles) spatially there is different degenerations, therefore need not tolerate this situation.In addition, because raceway groove entrance 20 is identical with temperature on channel outlets 22, there is identical ion diffusion rates, give the electric current existed in each position thus equal.The risk of the temperature rise that the higher electric current in local causes bipolar plate 10 local stronger is saved with this.Correspondingly there is no the higher electric current in local, exempt to cause the higher degeneration of electrolytic cell or fuel cell (such as, PEM-heap) local.
Conventionally when electrolytic cell or fuel cell operation, the life-span of electrolytic cell or fuel cell is determined by most thermal site, and affect its possible working method, and the favourable long-life of each electrolytic cell or fuel cell and lower deterioration velocity can be reached by means of the cooling of this at least one heat pipe 12 pairs of bipolar plate 10.In addition, electrolytic cell or the colder position of fuel cell is utilized under their possibility need not be tolerated in.Therefore by means of the uniform cooling of this at least one heat pipe 12 pairs of bipolar plate 10, can reach the efficiency improving electrolytic cell or fuel cell, this can contribute to the cell area/Structure of need space of reducing electrolytic cell or fuel cell needs.By by means of advantageously cooling bipolar plate with this at least one heat pipe 12, electrolytic cell or fuel cell are more uniformly made full use of, and can realize less and lighter electrolyte or fuel cell system with this, this especially may be used for movable application.
Preferably this at least one heat pipe 12 at least one cooling agent is filled.Such as, this at least one heat pipe 12 can use carbon dioxide, R410a, water and/or alcohol to fill as at least one cooling agent.Here all cooling agents enumerated all ensure all even reliable cooling of bipolar plate 10.Note, other cooling agents also can cool reliably for bipolar plate 10 in this at least one heat pipe 12.Use water as cooling agent is convenient to implement and nothing danger completely.In addition, the negative pressure (or connecing in two-phase cool cycles thereon at) of several millibars can be set simply in this at least one heat pipe 12, so that it is Celsius to make the boiling temperature of water drop to the several years.Such as, but for many application, bipolar plate 10 piles (temperatures as high 200 DEG C) at high temperature PEM battery/high temperature PEM not to be needed to apply negative pressure to coolant water.
Heat exchanger 24 is connected on this at least one heat pipe 12 of shown bipolar plate 10 in the embodiment of figure 1.At least one heat pipe 12 can pass through the first collection section 26 on each one end, and is connected to heat exchanger 24 by the second collection section 28 on each other end.The cooling device of electrolytic cell or fuel cell is formed with this bipolar plate 10 and heat exchanger 24 (perhaps with collection section 26 together with 28).
Especially by means of collection section 26 and 28, cooling device can be implemented as the equal closed system of pressure, so that under making all heat pipes 12 be in identical pressure.Cooling agent can exist as biphasic mixture in the system closed.Such as, this cooling agent exists with liquid state in the first collection section 26 with at least one heat pipe 12, and this cooling agent is in the second collection section 28 with exist with gaseous state in heat exchanger 24.
In the closed system that pressure is equal, the heat in heat exchanger 24 can be released, and this causes cooling agent condensation in heat exchanger 24.Occur that local pressure declines by being condensate in heat exchanger 24 of cooling agent, the cooling agent of gaseous state is from least one first collection section 26 and/or at least one heat pipe 12 afterflow thus.In this at least one heat pipe 12, the quantity of the cooling agent of evaporation is identical with in the quantity of heat exchanger 22 condensation.Ben, in the closed system that pressure is equal, cooling agent always evaporates in most thermal site.Therefore in the whole plane of bipolar plate 10, identical temperature is automatically adjusted to by means of this mechanism.
Also without the need to driving electric energy to carry out heat to carry in the closed system that pressure is equal.Replace and automatically carry out heat conveying by means of the mechanism described in earlier paragraphs.In addition, the factor of the water conveying fast about 100 of self-adjusting hot delivery ratio in traditional cool cycles, because the conclusive pressure differential between evaporating point and condensation point balances with the velocity of sound of selected cooling agent.
Fig. 2 represents the schematic diagram of electrolytic cell or fuel cell.
Electrolytic cell shown in Fig. 2 or fuel cell can be called that PEM battery/PEM piles (ProtonExchangeMembraneStack proton exchange membrane stack).This electrolytic cell or fuel cell comprise at least one film 50 permeated hydrogen ion.The film 50 of hydrogen ion infiltration is arranged between two electrodes 52.In addition, this electrolytic cell or fuel cell also have two bipolar plate 10.What each bipolar plate 10 was arranged in electrode 52 deviates from the side of sensing with the permeable film 50 of hydrogen ion.
At least one bipolar plate 10 can be formed with the heat pipe 12 of at least one integrated (not shown), and the latter and/or can be formed in this bipolar plate 10 wherein.The execution mode of such as Fig. 1 can be used as bipolar plate 10 in this electrolytic cell or fuel cell.But as an alternative, at least one (not sketching the contours of profile) heat pipe 12 can also be arranged at electrolytic cell or at least one bipolar plate 10 vicinity of fuel cell.This at least one heat pipe 12 especially can contact each bipolar plate 10, and bipolar plate 10 and this at least one heat pipe 12 do not form compact subelement in this electrolytic cell or fuel cell.Even if in bipolar plate 10 or wherein at least one heat pipe 12 not integrated also can realize previously described advantage thus.
Film 50 can be used for implementing electrolysis or implementing fuel cell function for hydrionic permeability.In order to implement electrolytic cell function, electrode 52 generally applies a voltage.The voltage applied, such as, can be used for making molecule (such as, hydrone) be split into single atom.Cation (such as, hydrogen ion/hydrogen atom) is integrated on negative electrode in this case, and anion (such as, oxonium ion/oxygen atom) is attached on anode.(as educt, deionized water can be fed by least one serpentine channels 18 of bipolar plate 10.)
In order to implement fuel cell function, input different educts to electrode 52.Such as fill hydrogen at anode, and negative electrode input oxygen.Hydrogen ion is roamed by film 50 and reacted on negative electrode in this case becomes water.The electronics generation current that this anode discharges, can run for electric apparatus.
Not only when implementing electrolysis, and when implementing fuel cell function, by means of the battery that Fig. 2 schematically shows, between electrode 52 and film 50, all there is used heat.If this used heat is all produced by the electric current that flows through in these two processes, this electric current must overcome the resistance of film 50, electrode 52 and the contact be connected thereon.(thermal power of decline square is multiplied by resistance is provided by current strength.) in addition, when fuel cell operation to the energy of the exothermic reaction carried out as additional thermal release.By means of this at least one heat pipe 12, it or be arranged at least one bipolar plate 10 vicinity, or to be integrated at least one in bipolar plate 10, but the Homogeneous cooling of electrolytic cell or fuel cell can be ensured in both cases.Need not worry that electrolytic cell or fuel cell damage because its temperature improves with this.
