Field of the Invention The present invention relates to a fuel cell, and more particularly to a fuel cell having a multi-layered identical structure. [Prior Art] With the global energy consumption and the rise of environmental awareness, traditional energy sources such as oil and firepower have become less and less used, making research on new energy sources more and more, research on fuel cells. This is a very important part of it. The energy conversion efficiency of the fuel cell is high, up to 40%. If the technology of 5 忒 忒 ( (3〇§6116^^011) is used to recover the waste heat released during the reaction, the total thermal efficiency may exceed Eighty percent. In addition, the fuel cell 2 power generation process will hardly cause any pollution, and the fuel cell noise is also quite low. Currently, the fuel cell has a wide range of applications, including the power industry, transportation, space, military. In various fields, & has a number of products, such as power plants, backup batteries, portable power, stackers, robots, electric vehicles, small submarines, and even spacecraft and space shuttle power. In the battery, the proton exchange membrane (pEM; Pr〇t〇n with pyrazole # Membrane) fuel cell has the advantages of low reaction temperature, high energy density and material selection. The principle of proton exchange membrane fuel cell is hydrogen fuel and two The oxygen in the gas reacts electrochemically to generate electricity and water, and its basic structure includes the following components: a proton exchange membrane, a gas diffusion layer (including a catalyst layer), and Bipolar plate. The gas diffusion layer is placed on both sides of the proton exchange membrane, and is used for electrochemical reaction to generate electricity by the diffusion of hydrogen and oxygen into 200816552. The bipolar plates are respectively disposed on the proton exchange membrane and Both sides of the combination of gas diffusion layers are used to transport gas and collect current. However, the fuel cell of this basic structure has a fixed voltage and its fixed voltage is only about 1.23V, so it is necessary to connect a plurality of cells in series. In order to increase 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 are not compatible with portable electronic products. The need for miniaturization. In addition, 'the conventional stacked fuel cell needs to be designed with a locking element: and a gas delivery system (such as a pump or a fan) to make the fuel cell tightly assembled into a body and supply a gaseous fuel. Moreover, the weight, volume and manufacturing cost of the fuel cell are greatly increased. [Explanation] A fuel cell can be greatly reduced
