200826339 九、發明說明： 【發明所屬之技術領域】 本發明係為一種具有電壓量測裝置之燃料電池組，特 別係為量測單燃料電池單元電壓量測裝置之燃料電池組。 【先前技術】 燃料電池單元之操作電壓一般為0. 6〜0. 9伏特，但如 此小的電壓值並不足以推動大部分的用電裝置，因此實際 f 應用時必須將燃料電池單元串聯成燃料電池組用以提高燃 料電池組之電壓。燃料電池組至少需由兩個以上之燃料電 池單元組成，而串聯之數目依實際需求電壓決定◦根據電 學原理，燃料電池組之總電壓係為所有燃料電池單元之電 壓加總而成。 理想狀況下，當串聯燃料電池單元時，因為流經各燃 料電池單元之電流均相同，所以各燃料電池單元應該有相 同的電壓，但從熱力學及動力學的觀點來看，由於每個燃 I 料電池單元在不同區域溫度之分佈及反應氣體之流動條件 下操作，因此將會造成各燃料電池單元電壓之差異。再者， 在組裝燃料電池組時產生之誤差，亦會造成部分燃料電池 單元漏氣或氣體交叉流動（crossover)之現象，使得各燃料 電池單元電壓上有所差異。 在燃料電池組中只要有一個燃料電池單元發生斷路， 會使得整個燃料電池組無法發電，所以量測燃料電池單元 之電壓，對於燃料電池組之性能具有相當大的影響性，並 可以得知在組裝燃料電池組時，是否發生問題或是某一個 5 200826339 燃料電池單元發生斷路，可做為診斷燃料電池健康之依據。 量測燃料電池之燃料電池單元之電壓最簡單的方法是 以三用電表直接量測，然而在大部分的燃料電池組中，至 少都具有數十個以上之燃料電池單元，若要量測每一個燃 料電池早元之電壓，將勢必花費許多的時間。而另一個方 法是將電線端子直接附著於各燃料電池單元上，再將電線 端子外接至電壓記錄器。此方式又可分為兩種方法，一種 方法是在各燃料電池單元上鑽孔，再將電線端子埋入燃料 C 電池單元中，而另一種方法則是將電線端子黏著於各燃料 電池單元上再進行量測。但上述之方法最大的問題是在於 必須對每個燃料電池組進行相同且重複之工作，並且電線 端子與燃料電池單元間之電性連接常無法有效接觸，在測 試完成後又需將每一條電線端子取走，相當不符合實際量 測上之經濟效益。 【發明内容】 本發明係為一種具有電壓量測裝置之燃料電池組，燃 料電池組包括兩個以上之燃料電池單元，藉由在相鄰兩個 不同燃料電池單元之雙極板上設置一雙極板凹槽，導電插 頭母座插設於雙極板凹槽内，再將導電公插頭與導電插頭 母座作電性連接，並將導電公插頭固設且電性連接於電路 板上，使電壓量測裝置係與燃料電池組相結合。 爲達上述之功效，本發明提供一種具有電壓量測裝置 之燃料電池組，其包括：一燃料電池組，其具有至少二燃 料電池單元，每一燃料電池單元具有一第一極板及一第二 6 200826339 極板’任兩相鄰且不同單元之第一極板及第二極板處設有 -雙極板凹槽；至少-導電插頭母座，係為一彈片且具有 =㈣折部’錢卡設於該雙極板凹㈣並與雙極板凹槽 ^電接觸，又導電插頭母座具有—第—結合部及—第二社 二:少一導電公插頭’其係與第〜結合部及第二結合 =電制H電路板，固設且電性連接於導電公插 f, ^達上述之功效，本發明提供1燃料電池組之電壓 心衣置’係應用於一具有電壓量測襄置之燃料電池組， ^ 導電插頭母座’係為〜彈片且具有數個彎 简，、月力於該雙極板凹槽内與讀雙極板凹槽導電接 導^頭母座具有Γ第—結合部及—第二結i 、略/ Wa插頭’其係與該結合部導電接觸；以及 梵路板，固設且電性連接該導電公插頭。 %粗1達=述之x力效，本發供—種具有雙極板凹槽之 麵:二杯且係應用於-具有電壓量測裝置之燃料電池 冬,=7_電池組’其具有至少二燃料電池單元， 相鄰且不同單元之二J一極板及-第二極板，任兩 每旧槽。之4弟一極板及該第二極板處設有一雙極 康及=====置;使用可棱性之導電母插 間祛佳之電性接以提供電壓量測裝置與燃料電池單元 計，將電壓量測，，並針對不同燃料電池組之尺寸與設 量消彳後，可直拄衣置拉組化，且在完成燃料電池組之電壓 將以模組化之電壓量蜊裝置直接取下，以 200826339 節省電壓量測之時間。 藉由本發明的實施，至少可以達到下列之進步功效： 一、 提供一電壓量測裝置模組，並配合不同設計及尺寸大 小之燃料電池組，用以量測燃料電池單元之電壓。 二、 利用導電公插頭與導電插頭母座導電接觸，使得電壓 量測裝置與燃料電池組具有良好之導電接觸。 三、 利用導電公插頭可插拔之特性，方便量測燃料電池組 之電壓，以節省電壓量測之時間和成本。 【實施方式】 圖一係為本發明之一種燃料電池雙極板凹槽之立體實 施例圖。本實施例為一種具有電壓量測裝置之燃料電池組 10，其包括：一燃料電池組11 ;至少一導電插頭母座12 ; 至少一導電公插頭13 ;以及一電路板14。 燃料電池組11，其具有至少二燃料電池單元111，每一 燃料電池單元111之雙極板112具有一第一極板113及一 I 第二極板114，並於任兩相鄰且不同單元之第一極板113 及第二極板114處設有一雙極板凹槽115 ◦如圖一所示，雙 極板凹槽115係可設置於雙極板112之周邊或周邊之彎折 處。 至少一導電插頭母座12，其係為一彈片且具有數個彎 折部，其能卡設於雙極板凹槽115内並與雙極板凹槽115 導電接觸’又導電插頭母座12具有一第一結合部121及一 第二結合部122。其中，導電插頭母座12之材料係為一可 撓性材料。 8 200826339 圖 係為本發明之_ ^ ^ ± 離樣一。罔二技& 士 種^電插頭母座之立體實施例圖 _態‘ 導電㈣母座之平面實施 具有-第一脊折“二^母/12彈片_，使其 彈片部124及-第二彈片邱^成“有同方向延伸之一第一 g - ZS μ 邛25，再將第一彈片部124及 弟一弹片邛125向内側彎折，分 ^ ^ 弓何刀別形成一第二彎折部120， 由弟一穹折部126分 结人邻127 I伸出一弟一結合部121及一第二 Ο 二結合部121與第二結合部⑵再次沿 第-辯妬# H ^成一弟二彎折部127，進而由 弟二穹折部127分別延伸 田 圖二所示之形狀。 弟-弹片。P 128 ’以形成如 圖四係為本發明之一種導帝 態樣二。圖五係為纽日Λ 頭母座之立體實施例圖 例匕样-. —種導電插頭母座之平面實施 2 。將可撓性之導電插頭母座12彈片彎折，使立 部折I!23'’以形成同方向延伸之一第一結i 二及一弟一結合部122，，再將第一結合部i2二 f。22’向外側彎折，分別形成-第二彎折部I26,，二 第三彎折部！27，，進而由第-^^方向讀’以形成一 弟二穹折部127,分別延伸出一筮 二弹片部128,，如圖四所示之 斗忐a闽-斗、回 ν狀將^電插頭母座12設 广成如圖一或圖四之形狀，可使 板凹槽115作緊密之導雷桩缺 月W丄U興雙極 凹槽】財 ’且可穩固地插狀雙極板 至少—導電公插頭13，其係與導電 結合部】2〗及第二結合部】22 之弟一 年私接觸。其中，導電公插 200826339 頭13之材料係為一可撓性材料。 電公插頭之立體實施例圖。圖七係為太菸發明之一種導 插頭之平面實施例圖。如圖六所示，、、曾心^明之一種導電公 需與導電插頭母座12相符合，使得$ = ^插頭13之形狀 電插頭母座12之第一結合部121 /楚插頭丨3可與導 之導電接觸。 ” 一、、、"合部122作緊密 %%双1 a又丘电性迷接於 '[Technical Field] The present invention is a fuel cell stack having a voltage measuring device, in particular, a fuel cell stack for measuring a single fuel cell voltage measuring device. [Prior Art] The operating voltage of the fuel cell unit is generally 0. 6~0. 9 volts, but such a small voltage value is not enough to drive most of the electrical devices, so the actual fuel cell must be connected in series. The fuel cell stack is used to increase the voltage of the fuel cell stack. The fuel cell stack must be composed of at least two fuel cell units, and the number of series connected is determined by the actual demand voltage. According to the electrical principle, the total voltage of the fuel cell stack is the sum of the voltages of all the fuel cell units. Ideally, when the fuel cell units are connected in series, since the currents flowing through the respective fuel cell units are the same, each fuel cell unit should have the same voltage, but from the viewpoint of thermodynamics and kinetics, The battery cells operate under different regional temperature distributions and reaction gas flow conditions, thus causing differences in the voltages of the various fuel cell units. Furthermore, errors in the assembly of the fuel cell stack may also cause leakage or gas crossover of some of the fuel cell units, resulting in differences in the voltage of each fuel cell. As long as one fuel cell unit is disconnected in the fuel cell stack, the entire fuel cell stack cannot be generated. Therefore, measuring the voltage of the fuel cell unit has a considerable influence on the performance of the fuel cell stack, and it can be known that When assembling a fuel cell stack, whether a problem occurs or a 5 200826339 fuel cell unit is broken can be used as a basis for diagnosing the health of the fuel cell. The easiest way to measure the voltage of a fuel cell of a fuel cell is to measure it directly with a three-meter meter. However, in most fuel cell stacks, there are at least dozens of fuel cell units. The voltage of each fuel cell in the early morning will inevitably take a lot of time. Another method is to attach the wire terminals directly to the fuel cell units and then externally connect the wire terminals to the voltage logger. This method can be further divided into two methods, one is to drill holes in each fuel cell unit, and then the wire terminal is buried in the fuel C battery unit, and the other method is to stick the wire terminal to each fuel cell unit. Then measure. However, the biggest problem with the above method is that the same and repeated work must be performed for each fuel cell stack, and the electrical connection between the wire terminal and the fuel cell unit is often ineffective contact, and each wire is required after the test is completed. The terminal is taken away, which is quite inconsistent with the economic benefits of actual measurement. SUMMARY OF THE INVENTION The present invention is a fuel cell stack having a voltage measuring device that includes more than two fuel cell units by placing a pair on a bipolar plate of two adjacent different fuel cell units.
