Description of the Invention: [Technical Field] The present invention relates to a fuel cell structure, and more particularly to a fuel cell battery, which is designed to be far-flung and innovative in the soft material package. Fuel cell module designer. 孓~, [previous technology] energy autonomy - straight is a lot of _ care, but also the current family (four) to be economic issues. By the government and the general public to hide s, but also the scale #录钱__ to the more mechanical power, the money family is all actively developing alternatives. Li Niansi (four) enterprises Wei this reduction of private 胄 _: "In order to make medicine, science, Education 'social responsibility and the continuous development and improvement of the quality of life, we must ensure that there is enough money to increase the number of jobs." Therefore, in the case of the gradual exhaustion of oil supply, it is obviously necessary to find alternative energy sources. Things. At present, wind energy, solar energy and nuclear energy are the alternative energy sources that people know better. Recently, many countries in the European Union have begun to develop wind and solar power generation facilities. Less than one percent of the world's electricity is _ wind energy, but Denmark has Twenty percent of electricity is generated by wind power, and the EU continues to install new wind power equipment every year, such as the installation of 5.7 million kilowatts of power generation equipment in 2004. Although wind and solar energy are inexhaustible sources of energy, they are all affected by weather and have limited power supply capabilities. In addition, the Icelandic government allowed a few years ago to develop hydrogen energy, using local abundant hydro and geothermal power to produce hydrogen, and fuel cells to promote cars and boats to reduce carbon dioxide emissions to zero. The fuel cell is a power generation system that can be used multiple times. It uses the redox reaction of hydrogen and oxygen to efficiently convert chemical energy into 5 1318476 and convert it into electric energy, and it does not produce carbon dioxide to cause air pollution. The product is water and a little extra heat. Therefore, in recent years, many countries have begun to develop fuel cell power generation systems such as "solid oxide fuel cells" (referred to as "three-dimensional? (:) is used in large-scale power generation systems,, membrane electrode group fuel cells" (referred to as PEMFC) ) is used in small stationary power generation systems and replaces traditional automobile engines. 'Direct sterol fuel cells' (DMFC) is used in 3C electronic production and supply systems, etc. These applications make fuel cells a hot topic now. Using the electricity required by the electric power grid, it is possible to electrolyze water from the wind power of the solar power line to reduce the use of oil and indirectly reduce the carbon dioxide emissions. Of course, other energy sources such as water can be used again. Force, geothermal and tidal power generation can be used to produce hydrogen. It is further understood that 3C electronic products with unlimited power will be the ones that everyone is looking forward to, and they can enjoy the nature in the long-term or wilderness. At the same time, it has a high quality of life and keeps in touch with the outside world. The portable fuel cell is a small power generation system. As long as there is sufficient fuel, the system can continuously supply power and provide high quality and stable power. ^ Portable room temperature small membrane electrode group fuel cell has become the mainstream of fuel cells in recent years, and its technology is also compared. Mature, but the design required to apply it to high-wattage fixed power generation systems compares lions. But under her, can be fresh ^ pEMF (: power generation secret power is larger than another direct type methanol fuel cell) 'And the design on the system is relatively simple, so there is a chance to have commercialization first. _ PEMFC because of the small current, the management of water heat is relatively simple 'to the temperature of the PEMFC shaft is not high temperature, but because of the use It is pure hydrogen, and the amount of catalyst required for oxidation is less than that of DMFC', which greatly reduces the cost of the battery. The other item of the fuel cell is 6 1318476, which is the way to increase the voltage. In addition to the traditional stacking type, there are also a kind of flat-type method to form a battery module in series, which is usually used to provide a secret, and the battery is provided. The size of the fan is very suitable for use on small portable fuel cells. A. schmitz's group team mentioned in the paper towel of the 3rd year of the heart that they succeeded in making printed circuit boards (PCBs) for the flow path. • The plate is a battery and reaches the current of (10) ffiw/em2 just below the Mv (four) load, and the supply of oxygen in the battery is achieved by diffusion breathing. % However, the conventional small portable fuel cell, The whole fuel formed by stacking and stacking each of the four pools is in a four-fold manner. Usually, it is a hard-fitting material that is sealed into a fuel cell module and forms a flow that can connect the cells. Road space, this _ know miscellaneous battery Huanbao packaged financial still has the following problems: 1, heavy Dong is heavier: the appeal of portable products, lightweight is the key - so the known fuel cell module With the design of the metal material coating positioning, it is difficult to achieve the ideal weight reduction for the weight of the overall product. Lu 2 'Poor air tightness: Due to the internal barrier space of the fuel cell module, the shape of the cladding and positioning is difficult to form - and must be formed by the relative combination of the upper and lower modes; therefore, the conventional fuel cell mode domain Due to the design of the metal material wrap-like position, the upper and lower molds are connected to each other because of the strong recording state, and the financial error is the result of the gas leakage. 3, poor shock resistance: because the portable fuel cell can be used for tearing, in the dynamic environment, the probability of suffering from external impact, face or drop is greatly increased, therefore, the conventional fuel 1318476 battery module by The design of the metal material coating positioning will be relatively lacking the shock absorbing buffer effect due to the hard and brittle characteristics, and it is obviously disadvantageous for the internal battery structure assembly precision and the maintenance of the flow space tightness, thereby shortening the portable fuel cell module. The service life of the group. • Another problem is related to the plates and runners of the fuel cell stack. - The plates and runners account for most of the volume, weight and cost of the entire fuel cell, but the traditional plates are mostly Although graphite has good electrical conductivity, it has the disadvantage of high weight. Although there are also flow channels formed by processing metal plates, the conductivity of the metal flow channel is better (about graphite). One hundred times), but there are also problems of not being light, and it is also a problem to be improved. In view of the problems existing in the above-mentioned conventional fuel cell module packaging and positioning methods, how to develop an innovative design that is more in line with the portable use requirements and is more ideal and practical, is subject to the relevant industry and interested people. Think about breakthroughs. In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. With the above objectives, detailed design and careful evaluation, the inventor has finally obtained the practical invention.
