Description
本發明係有關一種燃料電池，尤指為一種平面式燃料電池模組。 The invention relates to a fuel cell, in particular to a flat fuel cell module.
燃料電池(Fuel Cell)是一種利用化學能轉化為電能的發電裝置，相較於傳統發電方式，燃料電池具有低污染、低噪音、高能量密度以及較高的能量轉換效率等優點，是極具未來前瞻性的乾淨能源，且其可應用的範圍包括攜帶式電子產品、家用發電系統、運輸工具、軍用設備、太空工業以及大型發電系統等各種領域。 Fuel cell is a type of power generation device that uses chemical energy to convert electricity. Compared with traditional power generation methods, fuel cells have the advantages of low pollution, low noise, high energy density, and high energy conversion efficiency. Future-proof clean energy, and its application scope includes various fields such as portable electronic products, home power generation systems, transportation vehicles, military equipment, space industry and large-scale power generation systems.
燃料電池的運作原理依其種類之不同會有些許差異，以直接甲醇型燃料電池(Direct Methanol Fuel Cell,DMFC)為例，藉由甲醇水溶液在陽極觸媒層進行氧化反應，產生氫離子(H+)、電子(e-)以及二氧化碳(CO2)，其中氫離子可以經由電解質傳遞至陰極，而電子則經由外部電路傳輸至負載作功之後再傳遞至陰極，此時供給陰極端的氧氣會與氫離子及電子於陰極觸媒層進行還原反應並產生水。 The operating principle of a fuel cell varies slightly depending on its type. Taking a direct methanol fuel cell (DMFC) as an example, an aqueous methanol solution is oxidized on the anode catalyst layer to generate hydrogen ions (H + ), Electrons (e-), and carbon dioxide (CO2), where hydrogen ions can be transferred to the cathode through the electrolyte, while electrons are transferred to the load through external circuits and then transferred to the cathode. And electrons undergo a reduction reaction in the cathode catalyst layer and generate water.
另因燃料電池每個基本電池單元所能提供的電壓很 小，因此在實際應用時必須串聯多個電池單元，才能達到所需求的操作電壓。 In addition, the voltage provided by each basic battery cell of the fuel cell is very large. It is small, so in practice, multiple battery cells must be connected in series to achieve the required operating voltage.
傳統兩燃料電池單元串聯時，主要是以導電的雙極板(Bipolar plate)透過機械壓力使電池單元串聯並分隔陰陽極的燃料，然而，使用雙極板的作法往往必須導入較大型的流體輸送元件，對於小功率或是體積較小型的燃料電池而言，電池單元組合傾向平面式的設計，因此平面式的電池單元串聯方式將是必須克服的課題。 Traditionally, when two fuel cell units are connected in series, a conductive bipolar plate is used to connect the battery cells in series and separate the cathode and anode fuel through mechanical pressure. However, the use of bipolar plates often requires the introduction of larger fluid transport. For a small-power or small-sized fuel cell, the combination of battery cells tends to a flat-type design. Therefore, a planar battery-cell series connection method will be a problem that must be overcome.

於一實施例中，該複數膜電極組單體係排列於同一平面。 In one embodiment, the plurality of membrane electrode groups are arranged in a single system on the same plane.

於一實施例中，該集電層單體表面之無抗氧化層區域係為移除連接該些集電層單體之間的連接柄或架橋所形成。 In one embodiment, the area without the oxidation-resistant layer on the surface of the current-collecting layer monomer is formed by removing a connecting handle or a bridge connecting the current-collecting layer monomers.
