[Prior Art] With the global energy consumption and the rise of environmental awareness, traditional % sources such as oil and firepower have become less and less useful, making the research and development of new energy sources more and more, fuel cells The study is a very important part of it. The energy conversion efficiency of fuel cells is high, up to 40%. If combined with the technology of cogeneration of cogeneration, the waste, release, and recovery of the reaction will be more than 100%. ten. Plus, the battery is charged: the power generation process will hardly cause any pollution. Moreover, the sound level of the fuel cell is also quite low.

Bipolar plates are placed on either side of the combination of the proton exchange membrane and the gas diffusion layer to deliver gas and collect current. However, the fuel cell of this basic configuration generally has a fixed voltage and its fixed voltage is only about 1.23V, so it is necessary to connect a plurality of cells of the fuel cell in series to improve the overall output voltage. Conventional stacked fuel cells are formed by directly stacking a plurality of fuel cells in series. However, the overall volume and weight of such stacked fuel cells are relatively increased, and thus do not meet the micro (four) requirements of portable electronic products. In the past, conventional stacked fuel cells need to be designed with a locking component net gas delivery system (such as a pump or a fan to make the fuel cell tightly assembled into a body that supplies gaseous fuel, volume, volume and manufacturing cost. Therefore, the present invention is based on the method of providing a fuel cell and a plurality of battery cells electrically connected to the same plane. In order to increase the overall voltage back to the mountain. Pull out and avoid greatly increasing the volume and weight of the fuel cell. Another method of the invention is to make the material "provide a fuel cell and its manufacture without using it."

Referring to Figures 1 and 2, Figure 2 shows the first % according to the present invention. The structure of the battery unit is composed of a membrane electrode assembly iio, an anode conductive sheet 120 and a cathode conductive sheet 13〇, and the membrane electrode assembly 11 is disposed on the anode conductive sheet 12 and the cathode. Between the conductive sheets 13 。. The electrode group 1 10 is a sheet-like structure formed of an electrolyte material, for example, a phosphoric acid type, a molten carbonate type, a solid oxide type or a proton exchange membrane type electrolyte material.

Referring to Figure 3, there is shown a cross-sectional view of a series battery unit in accordance with a first embodiment of the present invention. Since the single battery unit 1 has only a fixed power output, the fuel cell of the present invention electrically connects a plurality of battery cells 100 in series to increase the overall power output. As shown in Fig. 3, the battery sheets are arranged side by side on a plane, but each two adjacent battery cells 100a and lb have a gap a to separate each two. Battery cells I 1 (10)' and 1 〇 Gb. In the embodiment, the void a may be filled with, for example, an insulating material to isolate every two battery cells i 00 . When the electrical connection is made, the anode conductive sheet 120a of each battery unit 100a is electrically connected to the cathode conductive sheet 130b of the other battery unit i〇〇b on the adjacent side by the wiring 14〇. The battery cells 100a*1〇〇b are electrically connected in series, so that the fuel cell of the first embodiment can select the overall power output corresponding to the series number of battery cells.曰 It is worth noting that 'in Figure 3A, the two adjacent battery sheets 200816549 yuan 100a and 100b are used for detailed description, but the fuel cell of the present invention does not limit its battery unit. The number of series of turns is determined by the number of series connected to its battery cells 100 depending on the demand for electrical output. Referring to FIG. 1 and FIG. 3, when assembled, the battery cells 1 are first arranged on a plane and electrically connected to each other, and then the first platen 2 and the second platen 600 are tightly stabilized. The battery cells 1 are pressed together to the fuel supply device 500, and the battery cells are assembled by the cover plate 4 on the fuel supply device 500, thereby forming the fuel cell of the present invention. When the fuel cell is generating electricity, the fuel supply device 500 can uniformly supply hydrogen gas to the battery unit 1 , and the oxygen in the outside air can enter the battery unit 100 from the cover 4 , thus eliminating the need for a pump or fan system. The auxiliary cycle provides fuel. In addition, the battery cells (10) are arranged and electrically connected in series on the plane of the fuel supply device 500, so the fuel cell of the present invention can increase the overall output power' without significantly increasing the overall thickness and volume, and can meet the miniaturization of the fuel cell. Demand. Please refer to FIG. 4 to FIG. 6 , FIG. 4 is a schematic diagram showing the unfolded structure of the conductive sheet set according to the second embodiment of the present invention, and FIG. 5 is a schematic cross-sectional view showing the battery unit according to the second embodiment. Figure 6 is a perspective view showing a single battery unit according to the second embodiment of the present invention. Compared with the anode conductive sheets 12A and the cathodes of the battery cells (10) of the second embodiment, the lengths of the sheets (4) are shorter, and are connected and combined with the % pole conductive sheets 120 by using a connecting portion 15? And the cathode conductive sheet ^ ^ the power blocking sheet 130 to form a conductive sheet group 15 〇 4 ® such that the anode conductive sheets 12G are located on the side of the connecting portion - the cathode conductive sheets (10) are located at the connecting portion 15G - 12 200816549 = and the anode conductive sheets 12G and the cathode conductive sheets are electrically connected in series. The connecting portion 15G is made of an insulating material, and the combined position of the anode conductive sheet 120 and the cathode conductive sheet 130 corresponds to the set position of the battery unit (8). When the fuel cell of the embodiment of FIGS. 4 to 6 is roughly mounted, the plurality of membrane electrode groups 110 are first arranged on a plane, and then the two conductive sheet groups 16 〇 are used to correspond to the membrane electrode groups. 11〇, (as shown in FIGS. 5 and 6), and the anode conductive sheet i2Q and the cathode conductive sheet 130 of the conductive sheet group 16G are respectively sandwiched between the opposite surfaces of the membrane electrode groups 11 and thus formed. The battery cells 100' of each of the battery cells are electrically connected to the cathode conductive sheets of the battery cells i 与其 on the adjacent side thereof by the wires 140. Next, the assembled battery unit 1 is tightly pressed against the fuel supply device 500 by the first pressure plate 2 (8) and the second pressure plate 600 to form the fuel cell of the second embodiment. Therefore, by: the electric piece & 160 corresponding to the end of the membrane electrode assembly 11〇, so that the battery: the overall structure of the crucible 100 can be more encrypted 'to avoid the occurrence of structural combination The situation thus increases the power generation efficiency of the fuel cell. It can be seen from the above embodiments of the present invention that the fuel cell of the present invention can make the fuel supplied from the material supply device and the oxygen in the outside air uniform and enter the battery cells, thereby improving the overall power generation. effectiveness. Since the =^ milk system is directly supplied by the fuel supply device and the outside air, there is no "or fan to supply hydrogen and oxygen to the shield ring, thereby reducing the overall design of the components to reduce the volume and weight of the fuel cell. The structure of the fuel cell of the present invention is closely sealed and thus can further provide power generation efficiency. Although the present invention has been disclosed above by way of example, it is not intended to limit the present invention. It is expected that: meat, hibiscus a, without departing from the sleeves 4 of the present invention, shall be subject to the definition of the patent application scope and the scope of the patent application.
