Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to an electric energy supply device. [Prior Art] In recent years, due to the continuous pollution of traditional energy sources such as coal, oil and natural gas, causing serious pollution of the global environment and the global greenhouse effect, scientists are eager to find solutions to reduce traditional energy (four) use and dependence. And «Battery ((4)' is one of the choices for the development potential and practical value of heavy-duty. Compared with traditional internal combustion engines, fuel cells have high energy conversion efficiency, quiet operation, fast response and very low emissions. The rib point, therefore, the fuel cell quickly becomes a power source for, for example, a motor vehicle, or a mobile generator, or a mobile electric device. As shown in Fig. 1A, it is an exploded schematic view of a structure of a conventional fuel cell 1. The conventional fuel cell wipes include a conductive substrate 12a, a diffusion layer 14a, a membrane electrode 14c' diffusion layer 14b, and a conductive substrate 12b in order from top to bottom. The conductive substrate 12a and the conductive substrate are disposed corresponding to each other and respectively The reaction zone Rla, Rlb and the transfer zone Tia, Ding. For electrical conduction, the diffusion layer 14a adjacent to the conductive substrate 12a and The diffusion layer 14b adjacent to the conductive substrate 12b also has electrical conductivity, and the membrane electrode interposed between the diffusion layer 14a and the diffusion layer 14b, for example, corresponds to the reaction regions RU, R1 on the conductive substrate 12a and the conductive substrate 12b. The membrane electrode 14c has a two-catalyst layer 14 and a proton exchange layer 143 interposed therebetween. The proton exchange layer is a solid electrolyte, and the proton exchange layer 143 is used to separate the catalyst layers 141 and 142. And the fluid flowing between the conductive substrate 12a and the conductive substrate 12b is not mixed with each other. In the fuel cell 1, since the membrane electrode 14c separates the conductive substrate 12a such as the cathode from the conductive substrate 12b such as the anode, Avoiding leakage of fluid flowing between the conductive substrates 12a, 12b or mixing with each other 'a sealing body 18a, 18b' is provided between the membrane electrode 14c and the conductive substrates na, 12b, respectively, to prevent fluid leakage, and Since the general fluid is mostly a gas (for example, hydrogen), the sealing bodies 18a and 8b can also be referred to as a gas seal. In the prior art, the sealing bodies 18a and 18b are respectively disposed on the membrane electrode. Both sides of 14c, therefore, when the fuel cell 1 is assembled, for the positioning of each component, the sealing body 18a or 18b must first be placed on the conductive substrate 12a or the conductive substrate 12b. For example, when the sealing body 18b is placed on After the conductive substrate 12b is placed, the diffusion layer 14b, the membrane electrode 14c, the diffusion layer 14a, the sealing body 18a, and the conductive substrate i2a can be placed by using loose and sealed bodies. However, since the sealing bodies 18a, 18b are not fixed Adhered to the conductive substrates 12a, 12b, the components often have difficulty in positioning due to the sliding or moving of the sealing ribs of the sealing body, and are more likely to cause fluid leakage due to poor sealing effect. In addition, the fuel cell i may also be inaccurately positioned due to the positioning between the male seals 18a, 18b and the membrane electrode 14e, causing the fuel cell 1 to cause the tamper 18a after the -stage operation time due to vibration or heat expansion and contraction. A phenomenon of displacement between the 18b and the membrane electrode Mc affects the power supply performance of the fuel cell 1 nucleation. In addition, the right multi-steam fuel cell is connected in series and stacked on top of each other to form a power supply device of 201128835. The common connection method is as shown in FIG. 1B, and the multi-array fuel cell 1 can be screwed by the screw, by locking the screw up and down. The spiral green S, so that the fuel cells 1 can be closely stacked together to form a complete power supply device. However, as shown in FIG. 1A and FIG. 1B, if the force of the locking screw s is uneven or insufficient, the conductive substrate 12a and the diffusion layer 14a or the diffusion layers 14a, Hb and the film electrode 14c may be caused. Between, or the diffusion layer (10) and (4) the substrate 12b does not "make the touch impedance too ^ step-by-step, may cause the upper and lower two fuel cells} between the conductivity of the (four) impedance is too large and affect the power supply equipment The overall power supply performance. Aspect 'If the force when locking the screw S is too large, it may cause the internal components of the battery 1, such as the conductive substrate 12a, m, layer = 14b, etc. to be deformed or broken, so that the overall power supply of the power supply equipment The performance drop therefore 'how to provide a kind of electric energy supply ^ ^ a ^ 1 this, should be broken, its structure has good energy and two: and the combined power supply equipment also has a good power supply effect for men, for the month IJ is important One of the problems of the present invention is to provide a power supply device with a plug-and-talk effect, a fixed power efficiency, and a good supply for the above purpose.

In this embodiment, the two main surfaces of the conductive substrate 22a and the conductive substrate 22b are provided with the flow paths S2a, S2b, respectively. In addition, since the conductive substrates 22a and 22b must have both proper 201128835 properties (to support and protect the members sandwiched therein), appropriate elasticity (to absorb structural stress during assembly), and good electrical conductivity, Therefore, the materials used for the conductive substrates 22a and 22b are mostly graphite and polymer compositions.

In other words, between the conductive substrate 22a and the power conversion module 24, the first convex portion 261 forms a sealed space, so that the fluid flowing from the conductive substrate 22a to the region T2a can be sealed. Between the substrate 22a and the power conversion module 24, problems such as leakage of fluid or mixing of internal fluid with external fluid are avoided. Furthermore, the sealing structure 26 can be continuously or discontinuously disposed outside the periphery of the reaction regions R2a, R2b of the conductive substrates 22a, 22b, in order to avoid leakage when fluid flows in or out from the fluid transfer regions T2a, T2b.

The positioning structure Ca can be used to position the first protrusion 261 so that the sealing structure 26 can be easily and correctly positioned on the conductive substrate 22a, and the displacement of the sealing structure 26 is prevented to affect the sealing effect. In addition, in addition to the positioning structure Ca described above, at least one fixing structure (not shown) may be disposed at a position corresponding to the conductive substrate 22a, 22b and the sealing structure 26, so that the sealing structure 26 can be fixed by the fixing structure. The conductive substrates 22a, 22b are further provided to further prevent the sealing effect from being affected by the sliding or displacement of the sealing structure 26, wherein the fixing structure may be, for example, a hook body, a convex groove or a bump. The holding structure 28 abuts the periphery of the sealing structure 26 and abuts against the conductive substrates 22a, 22b. Here, the holding structure 28 is adjacent to the sealing structure 201128835 : Γ: wide example. Wherein the holding structure 28 can be, for example, π# / of the gate of the convex substrate 22a, 22b extending outward from the sealing structure 20, and the distance between the two ends of the conductive substrate. In addition, the horizontal extent of the retention structure 28 is limited. Preferably, the outer edge of the conductive substrate 仏, (10) is better, but the thickness of the non-strict (four) Γ structure 28 and the structure _ structure 28 of the galvanic conversion module 24 can be collectively referred to as two conductive substrates. A sealing body 3. . , the structure 26 and the holding structure ~, it is mentioned that 'the above-mentioned sealing structure 26 and the holding structure 28 can be Γ, 'is an independent structure' or can be a body-formed structure, here, - Body forming is an example. In addition, the sealing structure 26 and the holding structure can be composed of an elastic body, and the material of the sealing structure 26 and the contact preventing material 28 is, for example, a stone, a polyvinyl chloride, a polyethylene, a polypropylene, a polystyrene or the above materials. combination. Therefore, the elastic sealing structure % and the holding structure = the flow of assembly in the electric power supply device 2 + can be used to absorb the partial assembly I force. On the other hand, due to the elastic sealing structure 26 and the retaining structure to additionally absorb the assembly The stress allows the power supply device 2 to "encompose the assembly force of the 乂 π" to further enhance the structural strength of the power supply device 2 and achieve sealing and fixing effects. Further, when the plurality of power supply devices 2 are connected in series and stacked one by one, In the case of the power supply device, since each of the power supply devices 2 has the above-mentioned holding structure 28, and the thickness thereof is substantially equal to the thickness of the power conversion module 24, when the core is combined into a power supply device to lock the screws on the screws on both sides, The distance between the two conductive substrates 22a, 22b can be maintained without causing deformation or even cracking of the internal components of 201128835. Therefore, deformation or cracking of internal components caused by too large or too small locking force can be avoided. It is a problem that the contact impedance is too large, so 'not only can the structure of the electric energy supply device 2 have a good fixing effect' and is combined The electric device can also have good power supply performance.
