Fuel cells can be traced back to scientists in the 19th century in Europe. As early as 1838, Professor CF Schonbein discovered the electrochemical effects of fuel cells and emphasized that the gas or oxygen on the hydrogen and platinum electrodes could undergo a chemical reaction. The electric φ flow is generated, and in the next year, in the experiment of water electrolysis in 1839, Sir William R. Gr〇ve used electricity to decompose water into hydrogen and oxygen and in turn reversed the reaction of hydrogen and oxygen to generate electricity, thus proving the fuel. The principle of battery operation, and the fuel cell "Full cell" word was proposed by two chemists, L. Mond and C. Langer in 1889, to replace oxygen and hydrogen with air and industrial gas respectively to create the first practical The fuel cell. However, due to the extensive exploitation of oil and the widespread use of internal combustion engines, the development of fuel cells is like ice, but there are still research and applications related to fuel cells, the most representative of which is the 1960 Gemini space mission. The fuel cell used in the battery is lighter than the battery, and its chemical characteristics are higher than the stability of the power density. The battery of the battery can be used as the drinking water of the spaceman, so the fuel cell plays the main power of the spacecraft. source. ^ In the past few years, 'finding alternative energy sources are widely studied and discussed by all walks of life." Fuel cells, one of the future alternative energy sources that are very important to the party. The principle is to convert chemical energy directly into electrical energy. Today, fuel cells have evolved over the years, depending on electrolytes and operating temperatures. Many different forms of 1328307 P32-011 have emerged. If separated by electrolytes, they can be divided into alkaline fuel cells (AFC). Proton exchange membrane fuel cell (PEMFC), phosphoric acid fuel cell (pAFC), molten carbonate fuel cell (MCFC), solid oxide fuel cell (s〇FC), direct methanol fuel cell (DMFC). Right by operating temperature 'Can be divided into low-temperature fuel cells (operating 'with a degree of 5 〇 ~ 2 〇〇 C), common AFC, PEMFC, DMFC; medium temperature fuel cell (surface temperature 160 ~ 220. 〇, common with pAFC; High-temperature fuel cells (operating four degrees 600~1000 °C), common are mcfc, s〇fc. The characteristics of various fuel cells are as follows: (1) Accredited fuel cell (AFC) with asbestos net as the carrier of electrolyte , potassium hydroxide $〇 The printing solution is an electrolyte, and the operating temperature is between 7G and 12G ° C. AFC uses pure hydrogen as the anode fuel gas and pure oxygen as the cathode oxidant. The fuel limit is very strict. The electrolyte rot # is strong, so the battery life is short. The scorpion father's membrane fuel cell (pEMFC) uses a solid polymer membrane with conductivity as the electrolyte, and the operating temperature is below l〇〇t>C. PEMFC uses § gas as fuel, but not excessive c Helium gas (the tolerance is <1 Oppm). In order to avoid poisoning of the anode catalyst, the only liquid in pEMFc is water. The management of 4 water is an important factor affecting the efficiency of the fuel cell. (3) Acid filling The fuel cell (pafc) uses 1 〇〇/〇 phosphoric acid as the electrolyte, and the operating temperature is about 16 〇 22 22 °. The PAFC fuel must be externally reformed and the concentration of cq in the fuel gas must be less than 0.5%. 'Otherwise it will lead to catalyst poisoning. Due to the influence of acidic electrolytes, the life of PAFC will be more than 4 〇, 〇〇〇 hours.

Because the smelting carbonate is corrosive and volatile, the battery life is short. (5) Solid oxide fuel cell (s〇FC) The electrolyte used is solid non-porous metal oxide. The substance is generally used as YSZ (exchanged into the oxidation of O2, 1 jzed_Zr〇2). The operating temperature is between 650 and 1 〇〇 (TC. Because the operating temperature required by S0FC is very high, the metal and ceramic materials are not easy to seal, and the battery startup time is long, so it is not suitable for emergency electric φ adjustment, - ' (6) Direct methanol fuel cell (DMFC) 'DMFC is an extension of the PEMFC series, which uses a polymer membrane as an electrolyte.

Therefore, the proton exchange membrane can be solved due to water content. Insufficient, resulting in the problem of reduced proton exchange membrane conductivity. The new catalyst of DMFC is still being developed, and if it can enhance the catalytic activity of methanol, it can greatly improve the battery performance. X • , the above various fuel cells directly methanol Fuel cells are considered to be the most promising applications for low-power 3C electronics because they provide high energy and power density, low pollution, temperature close to room temperature, and rapid and effective replenishment of solutions. In the product. Although the main advantage of the direct-type battery is a simple system, it is more likely to be applied to the electronic products that can be used, but it also has two biggest problems that must be solved: - the penetration of methanol The problem is that the other is the low activity of the catalyst of the anode for methanol oxidation. The above two problems are caused by the direct sterol fuel cell. The main factors that are limited and the cost cannot be reduced, 34]. Currently, the widely used dipolar plates of dmfc contain flow channel design, and have the function of transporting fuel and collecting electrons. Most = 1328307 p32-011 layer is metal collector plate The electrons are connected to the cathode of the external circuit through the anode metal collector plate to form a loop. The main material classification of the bipolar plate is as follows: graphite bipolar plate, metal bipolar plate and composite bipolar plate. Generally direct methanol fuel cell single The design of the battery of the Single Cell is mainly based on the grid type flow channel, the gate block type flow channel, the meandering flow channel, and the interdigitated flow channel. However, since the anode fuel is liquid, the density is high. Therefore, it is better to use a design with lower flow resistance. In addition, for more battery cells, the sterol fuel needs to be uniformly supplied to each cell, so that each cell can have uniform performance. The current development of direct methanol fuel cells is highly valued, but most of them are currently in the laboratory stage and have not yet been commercially available. Among them, bipolar plate replacement materials or new processing methods. It is a research that is highly valued because it can reduce costs and has the potential for mass production. In the above various fuel cells, the battery characteristics and power generation capacity are shown in the market. In portable power applications, there are PEMFCs. SOFC, DMFC, and in vehicle power applications, there are PEMFC, MCFC, SOFC in commercial power applications, MCFC, SOFC in industrial power, and SOFC in distributed power plants. Today, after the first century, there are many experiences and applications in the world that use fuel cells. Today's society is also beginning to develop fuel cells as portable or multi-purpose mobile electronic products. The DMFC has a simple system structure. The high density unit density, low battery operating temperature and other characteristics, so direct methanol fuel cells are particularly suitable for power applications, mobile phones, PDAs, notebook computers 1328307 p32-0ii. The first figure is a schematic diagram of the reaction mechanism of a conventional direct methanol fuel cell (DMFC). The basic structure is divided into an anode 11, an anode diffusion layer 14', an anode catalyst layer 13, a proton exchange membrane PEM, a cathode catalyst layer 15, and a cathode diffusion layer 16. And the cathode gas flow path 12 and the like. The anode is an aqueous methanol solution, methanol (CH3〇H) and water (h20) are passed through the anode diffusion layer 14 to the anode catalyst layer, and the methanol (CH3〇H) molecule is decomposed into positively charged hydroquinone protons, carbon monoxide (C). 〇 2), with electron e-' hydrogen ions passing through the porous proton exchange membrane ρεμ to the cathode; the cathode gas is passed through the cathode diffusion layer 16 to the catalyst layer 15, and the oxonium is cleaved into a negatively charged oxygen ion 'electron Through the external circuit to the cathode, electrons form water with zero hydrogen ions and oxygen ions. The total chemical reaction is as shown in formula (1), the fuel of the anode is sterol and water, and the anode product is carbon dioxide; the fuel of the cathode is oxygen, and the product is water, and its basic direct methanol fuel cell (DMFC) The reaction formula is as follows: Anode reaction: CH3〇H + H2〇_► C〇2 + 6H++6e·, En =0.046V (1) 3 Cathodic reaction: i〇2 + 6H++6e- ~~► 3H2 〇* En =1.229V (2) Total reaction: CH3OH+|〇2 + H2〇__► C02+2H20, En = 1.183V (3) In equation (1), En is the electromotive potential of the fuel cell , or called open circuit voltage (0pen-circuit v〇itage, 〇cv). At present, the single cell flow channel plate design of the proton exchange membrane fuel cell is mainly based on the grid type flow channel, the gate block type flow channel, the meandering flow channel, and the finger fork, etc. 1328307 p32-011 Directly Alcohol fuel cells basically use the above form, but since the anode fuel is liquid and has a high density, it is preferable to adopt a design with a lower flow resistance. In addition, for a battery pack with more cells, it is required that fuel can be uniformly supplied to each cell, so that each cell can have uniform performance. In addition, the yin-yang bipolar plates of direct sterol fuel cells (DMFC) are similar to proton exchange membrane fuel cells (PEM FC) and should have the following basic functions to achieve good battery performance: (1) Separating oxidant and reducing agent To avoid the effect of hydrogen (PEM FC) sterol (DMFC) through the plates to create a crossover. (2) Excellent mechanical strength so that the bipolar plate can be in balanced contact with the MEA to collect current. (3) Appropriate flow channel design, so that the fuel can be evenly distributed into the Cell, producing a uniform electrochemical reaction, and the product carbon dioxide is discharged at the anode, and the cathode can take away the product water to avoid the phenomenon of water accumulation and reduce the battery. efficacy. (4) Good thermal conductivity, uniform temperature inside the battery, and heat and temperature control. (5) Excellent electrical conductivity to collect current. (6) The appropriate opening ratio of the electrode plate, the ratio of the flow field groove area to the total electrode area should have an appropriate ratio. If the opening is too high, the contact resistance between the MEA and the bipolar plate will be too high and the performance will be reduced. If the opening is too low, the utilization of the MEA catalyst will be reduced, and the resistance of the internal flow field will be too high, which will also reduce the battery efficiency. 1328307 p32-011 (7) Low density to reduce the weight of the battery. Currently widely used bipolar plates, many of which contain flow channel design, have the function of transporting fuel and collecting electrons, the outermost layer is a metal collector plate, and the electrons are connected to the cathode of the external circuit through the anode metal collector plate to form a loop. The main materials of the bipolar plates are classified as follows: (1) Graphite bipolar plate non-porous graphite plate, which needs to be mixed with graphite powder and 2500 °C after being mixed with graphitizable resin, requires a long carbonization time, and needs to be mechanical after forming. The way of depicting the flow field is quite expensive. Therefore, the addition of graphite powder to the thermoplastic or thermosetting resin by hot pressing or injection molding of carbon-polymer composites can reduce the cost, but it will increase the double The resistance of the plate. (2) Metal bipolar plates are made of metal as a bipolar plate material. They are an alternative material, such as aluminum, titanium alloy, stainless steel, etc. The main considerations are low cost and easy to manufacture, but due to the proton exchange membrane fuel cell or direct Methanol fuel cells are acidic after the reaction and therefore require corrosion protection. (3) The composite bipolar plate combines the characteristics of various materials, and is made of thin gold metal (0.1-0.2 nm) as a partition plate. The frame is framed by polycarbonate or the like to bond it to the metal to be injection molded. The porous carbon plate prepared by baking is used as a flow field plate, and a thin layer of conductive adhesive is bonded between the metal and the carbon flow field plate. 12 1328307 - p32-〇n On the other hand, the disc production technology is quite mature, but it has not been applied to the production of fuel. Therefore, how to make the shape of the fuel cell by the production technology of the disc The shape of the sheet, in order to increase the scope of application of the fuel cell, is the concern of this case. SUMMARY OF THE INVENTION φ The purpose of this case is to address the lack of conventional technology, to propose - innovative process and device 'application disc production technology in the production of fuel cells, thereby reducing production costs, volume, and light weight Practical purpose.
