The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims. [Embodiment] An embodiment of the present invention will be described with reference to the drawings. Fig. 2A is a perspective view showing a fluid flow field plate assembly of one embodiment of the present invention, and Fig. 2B is a schematic cross-sectional view showing a fluid flow field plate in the direction of one of the fluid flow paths in Fig. 2A. As shown in Figures 2a and 2B, an exemplary fluid flow field plate assembly can be used in a fuel cell system or as part of a fuel cell system. Although a rectangular or rectangular-like structure is shown in Figures 2A and 2B, the fluid flow field plate assembly 1 can be constructed in a variety of shapes, sizes, and designs depending on its application. The fluid flow field plate assembly 10 can include one or a plurality of flow channels C exposed to a first side S1 thereof, and the flow path c can have a direction extending in different directions but extending substantially along a central axis or a fluid distribution plane The pipe section of 201121121, such as the axis or plane shown by line A of the fluid flow field plate assembly 10. Furthermore, the fluid flow field plate assembly 10 can include a first manifold 11 and a second channel 12 formed in the flow channel C and connected to the flow channel C. As shown by the arrows in Figures 2A and 2B, a reactant/incoming fluid can enter the first manifold 11 from a first end 101, for example, via a fluid inlet of the fluid flow field plate assembly 10. A portion of the incoming fluid can flow through one of the flow channels C, which provides a reaction zone to the fluid (release fluid) that is released into the conduit, for example, a reaction zone having a membrane electrode set of a fuel cell system. The fluid can then be discharged via the second manifold 12, and the effluent fluid can exit the fluid flow field plate assembly via a second end 102, which can be one of the fluid flow field plate assemblies 10 fluid outlets. In one embodiment, the fluid flow field plate assembly 10 can include a first manifold 11 , a second manifold 12 , and one or more fluid streams coupled between the first manifold 11 and the second manifold 12 .

The first manifold 11 has its fluid inlet for receiving the incoming fluid and extending in a first direction (eg, in the directions indicated by the arrows in the upper right of FIGS. 2A and 2B) to provide for One direction is partially delivered into one of the fluid conduits. The second manifold 12 has its fluid outlet for discharging a discharge fluid, and the discharge fluid as described above may include a portion of the incoming fluid (or all of the incoming fluid that has been reacted). The second manifold 12 may extend in a second direction (eg, in the direction indicated by the arrow in the lower left in FIG. 2A and FIG. 2B) to provide a portion for discharging the exhaust fluid in the second direction. pipeline. As shown in Fig. 2B, the second manifold 12 receives the effluent fluid via at least one effluent fluid inlet 14 located in the second manifold 12. Fluid flow path C, 201121121, as shown in FIGS. 2A and 2B, may be at least one of a distribution outlet (eg, distribution outlet 15) coupled to the first manifold]1 and a discharge fluid inlet of the second manifold 12. Between at least one of (e.g., the discharge fluid inlet 14) for dispensing at least a portion of the fluid from the first manifold. In one embodiment, fluid flow path C can have a plurality of conduit regions extending in at least two directions and extending substantially along the fluid distribution plane, which is parallel to line A shown in Figure 2A. Therefore, a portion of the released fluid can flow through the fluid flow path C and through the distribution outlet to the second manifold 12 as an exhaust stream. As shown in Fig. 2A, the first direction and the second direction may be substantially parallel to the fluid distribution plane. In one embodiment, the first manifold 11 and the second manifold 12 may be embedded in a fluid flow field plate assembly. For example, the fluid flow field plate assembly 10 can have a first manifold 11 and a second manifold 12 incorporated into the assembly that can be fabricated as one or more molded parts. The first and second manifolds 11 and 12 may extend substantially along the central axis or fluid distribution plane A (or substantially parallel to the central axis or fluid distribution plane A). In some embodiments, the flow resistance can be reduced to provide a uniform or substantially uniform flow rate and/or to provide a uniform or substantially uniform concentration of the reactant fluid being dispensed. In some embodiments, increased consistency in flow rate or concentration may improve the efficiency of a fuel cell device having a fluid flow field plate assembly. Figure 2C is a schematic cross-sectional view showing one of the first manifolds in the fluid flow field plate assembly of Figure 2A.

The first manifold 11 may have one or more openings 110 as a distribution outlet, and the openings 110 may be opposite, one of the sections of one of the first-channels u occupying approximately one of the first lanes. An angle range from one degree to about 180 degrees Θ. In one embodiment, the opening 110 can be formed on the lower left side thereof and can be in communication with one or more flow paths C. As an example, a reference point may be set at a bottom point of the first lane 11 with respect to a center point of a section of the first lane π. As shown in Fig. 2C, the opening 11 occupies an angular range θ (e.g., 75, 80 or 85 degrees) which is close to 90 degrees and can be opened from a point (bottom point) of about 〇 to about 70 to 85 degrees. If a similar opening is made in the lower right quarter of the circular section, the opening 110 will extend from approximately the point of the twist (bottom point) to approximately _7 至 to -85 degrees. Similarly, the second manifold 12 has a circular cross section and an opening that can serve as an exhaust fluid inlet 14 in one of the second manifolds, at least in a portion of the wall region. In an embodiment, the opening may occupy an angular position from about _9 () degrees (3 o'clock position) to -180 such as 2 o'clock position) relative to the center of the cross section of the second channel, for example, The structure in Figure 2 is shown. In some embodiments, the opening in each of the lanes may be in any angular range from about the center of the cross-section of the manifold to the extent of the extent of the lane-to-area to about 180 degrees. In one embodiment, the fluid flow field plate assembly 1 may be a combination of one, two or more seven pieces. Figure 3 is a perspective view showing a fluid flow field plate assembly according to another embodiment of the present invention, and a third drawing showing a section of the fluid flow field plate assembly in the direction of the fluid flow path according to Figure 3A. schematic diagram. As shown in Figures 3A and 3B, the fluid flow field plate assembly 10 can include a body 13, a first channel element B1, and a second channel element B2. The body 13 may include one or a plurality of flow passages C formed on its side. The first lane 11 and the second lane 12 may be embedded in the first channel element B1 and the second channel element B2, respectively. As shown in FIGS. 3A and 3B, the first channel element B1 and the second channel element B2 may have a substantially elongated shape and are bonded or attached to the upper and lower sides, respectively. The main body 13 is such that the flow path C can communicate with the first and second channels 11 and 12.

As shown in Figures 4A and 4B, each of the fluid flow field plate units 1 further has a first passage 111 and a second passage 112 extending through. The first passages 111 of the adjacent fluid flow field plate units 1 are connected to each other, and the second passages 112 of the adjacent fluid flow field plate units 1 are connected to each other. Therefore, the plurality of first passages 111 and second passages 112 may respectively include a first lane 11 extending through the fluid flow field plate assembly 10 and a second passage 21 . In particular, the fluid flow field plate assembly 10 in FIGS. 4A and 4B includes two plugs B disposed on the first end 1 and the second end 1〇2 to seal the first difference. An opening in one of the ends of the track 11 and the second manifold and avoiding cold leakage of the reactant fluid. In addition, the fluid flow field plate assembly 1 further includes a first protruding portion 1110 and a second protruding portion 1120. The first protruding portion 1110 and the second protruding portion 1120 are respectively connected to the adjacent fluid flow field plate unit 1 One channel 11 丨 and second channel. Referring to the figure, the first channel 111 and the second channel I12 of the adjacent fluid flow field plate unit 1 may also be connected by the elastic tube T to form a force il body flow field plate assembly having a plurality of flow paths c. 10 ° The present invention provides a fluid flow field plate assembly for a planar fuel cell device. The fluid flow field plate assembly can include at least one of the first channels exposed to its sides and one of the first and second channels connected to the flow path via a fluid transfer. A reactant fluid can enter the first manifold from one of the first ends φ of the fluid flow field plate assembly and flow through the flow passage to the second manifold. The reactant (or reacted) fluid can then be discharged from the second end of the fluid flow field plate assembly via the second manifold. In some embodiments, since the first and second channels are embedded or integrated into the fluid flow field plate assembly, the flow resistance can be effectively reduced to promote the flow through the fluid field plate assembly. Fluid transfer. Further, in some embodiments, the inconsistent distribution concentration of the reactant liquid in the fluid flow field plate assembly (or cross flow channel) can be avoided or reduced' to improve the efficiency of a fuel cell device.
