燃料電池係一種藉著電化學反應，直接利用含氫燃料和空氣中氧產生電力和熱能的裝置。由於具有低污染、高效率的乾淨發電技術，可應用於發電機組、車輛動力與可攜式電力等，因此成為近年來美、日、歐各國爭相研發及推廣的對象。雙極分隔板(Bipolar current collector-separator)是燃料電池(Fuel Cell)重要組件，雙極分隔板主要功能有五：(1)當作燃料氣體(如氫氣H2)及氧化劑(如氧氣O2或空氣)氣體分隔板，(2)在雙極分隔板兩表面有氣体導流凹槽分佈當作氣体導流槽，(3)當作在陰極及臨近另一電池(cell)陽極之電流傳導，(4)當作電流收集器，(5)也可在雙極分隔板內部加入冷卻劑導流管去除電池熱量。它可防止燃料氣體(如氫氣)與氧化劑(如氧氣)相混合，因此，雙極分隔板必須是對氣體有高不透氣性、高的電傳導性及耐腐蝕的薄片，在使用設計上也希望 雙極分隔板薄片能做得儘可能薄化，使燃料電池體積變小，並且改進電及熱傳導性，以便達到更經濟性及多樣化之燃料電池。 A fuel cell is a device that directly uses hydrogen fuel and oxygen in the air to generate electricity and heat through an electrochemical reaction. Due to its low-pollution and high-efficiency clean power generation technology, it can be applied to generator sets, vehicle power and portable power. It has become the target of research and development and promotion in the United States, Japan and Europe in recent years. Bipolar current collector-separator is an important component of fuel cell. The main function of bipolar separator is five: (1) as fuel gas (such as hydrogen H2) and oxidant (such as oxygen O2). Or air) gas partitioning plate, (2) having a gas guiding groove on both surfaces of the bipolar separator plate as a gas guiding groove, and (3) acting as a cathode and adjacent to another cell anode Current conduction, (4) as a current collector, (5) a coolant conduit can also be added inside the bipolar divider to remove battery heat. It prevents the fuel gas (such as hydrogen) from mixing with the oxidant (such as oxygen). Therefore, the bipolar separator must be a sheet with high gas impermeability, high electrical conductivity and corrosion resistance. also wish The bipolar separator sheet can be made as thin as possible, the fuel cell volume is reduced, and electrical and thermal conductivity are improved to achieve a more economical and diverse fuel cell.

Therefore, it can be quickly combined with electronic components to generate high-temperature and high-heat electronic components (such as a central processing unit, a light-emitting diode, a laser diode, etc.). The heat is conducted out, so it can be used as a heat dissipating element as a bipolar separator sheet.

以上之概述與接下來的詳細說明及附圖，皆是為了能進一步說明本創作達到預定目的所採取的方式、手段及功效。而有關本創作的其他目的及優點，將在後續的說明及圖式中加以闡述。 The above summary and the following detailed description and drawings are intended to further illustrate the manner, means and effects of the present invention in achieving its intended purpose. Other purposes and advantages of this creation will be explained in the following description and drawings.
以下係藉由特定的具體實例說明本創作之實施方式，熟悉此技藝之人士可由本說明書所揭示之內容輕易地了解本創作之優點及功效。 The embodiments of the present invention are described by way of specific examples, and those skilled in the art can readily understand the advantages and effects of the present invention from the disclosure of the present disclosure.
本發明之主要目的在於利用金屬基薄片具有良好之延展性、導電性、機械加工性、氣密性及成本低等優勢， 結合具有良好之抗腐蝕性的高導熱石墨紙，並加上蓬鬆石墨片或粉，以製備出散熱效果良好、導電度高及抗腐蝕之金屬基薄片複合石墨薄片。 The main object of the present invention is to utilize the advantages of good ductility, electrical conductivity, machinability, airtightness and low cost of the metal-based sheet.

The present invention utilizes a metal-based sheet to puncture a hole or make an expanded web, thereby forming a porous metal-based sheet. The perforated metal-based sheet has a roughened surface with a metal sharp corner protruding due to the punching relationship, and the rough surface of the metal sharp corner forms a mechanical bond when combined with the high thermal conductive graphite paper. When the other high-conductivity graphite paper is directly pressed with the porous metal-based sheet, the metal-based sheet holes cannot be filled, so in this embodiment, fluffy is added between the high-heat conductive graphite paper and the porous metal-based sheet. Multi-layer graphene or worm-like graphite or fluffy graphite powder as interface material, its function can not only fill the pores of metal-based sheets, but also flatten the wrinkled high-conductivity graphite paper and increase the heat of high thermal conductivity graphite paper.

And strengthen the bonding force between the metal-based sheet composite graphite sheet material, the process steps are as follows: first obtain a stainless steel metal-based sheet, a worm-like graphite sheet, a pyrolytic graphite paper (thermal conductivity coefficient 1600W / mK); stainless steel metal The base sheet, the worm-like graphite sheet, and the thermally cracked graphite paper are continuously placed in the mold, and then the mold is hot pressed in the mold, wherein both sides of the worm-like graphite sheet are sprayed or coated with epoxy resin to strengthen the metal. The strength of the base sheet composite graphite sheet was measured to have a resistance of about 16 to 23 mΩ, and the stainless steel sheet was measured to have a resistance of about 240 to 600 mΩ.
