Description
本發明係與固態氧化物燃料電池之檢測裝置有關，特別是指一種固態氧化物燃料電池檢測裝置之承載結構。The present invention relates to a detection device for solid oxide fuel cells, in particular to a supporting structure for a detection device for solid oxide fuel cells.
固態氧化物燃料電池(SOFC)主要由空氣電極、固態氧化物電解質以及氫氣電極所組成。A solid oxide fuel cell (SOFC) is mainly composed of an air electrode, a solid oxide electrolyte and a hydrogen electrode.
欲檢測固態氧化物燃料電池的效能時，係藉由固態氧化物燃料電池的檢測裝置進行測量，其中，請參閱如中華民國第I456230號專利所提供一種開放式平板型固態氧化物燃料電池單元檢測裝置，其包含一承載機構(1)；一連通設於承載機構一面上之氣體傳輸機構(2)；以及一連通設於承載機構另一面上之燃料傳輸機構(3)。藉此，可將固態氧化物燃料電池設置於承載機構中，並分別由氣體傳輸機構與燃料傳輸機構通入空氣及所需之燃料於承載機構中進行反應，由外部設備檢測固態氧化物燃料電池之效能狀態。When the performance of the solid oxide fuel cell is to be tested, it is measured by the detection device of the solid oxide fuel cell, among which, please refer to an open flat plate type solid oxide fuel cell unit test provided by the Republic of China Patent No. I456230 The device comprises a bearing mechanism (1); a gas transmission mechanism (2) communicated with one side of the bearing mechanism; and a fuel transmission mechanism (3) communicated with the other side of the bearing mechanism. In this way, the solid oxide fuel cell can be arranged in the carrier mechanism, and the gas transmission mechanism and the fuel transfer mechanism respectively introduce air and required fuel to react in the carrier mechanism, and the solid oxide fuel cell can be detected by external equipment. performance status.
習用的承載機構主要包含陰極分流板(空氣電極導流板)、陰極集電網(空氣電極側集電網)、陽極分流板(氫氣電極導流板)及陽極集電網(氫氣電極側集電網)，其中空氣電極導流板及氫氣電極導流板使用之材質係由氧化鋁之陶瓷所組成，其特點是質地較無延展性。The conventional bearing mechanism mainly includes cathode shunt plate (air electrode guide plate), cathode collector network (air electrode side collector network), anode shunt plate (hydrogen electrode guide plate) and anode collector network (hydrogen electrode side collector network), Among them, the material used for the air electrode guide plate and the hydrogen electrode guide plate is composed of alumina ceramics, which is characterized by a relatively non-ductile texture.
固態氧化物燃料電池的運作，主要區分為正反應與逆反應二種運作模式。將固態氧化物燃料電池設置於習用承載機構進行正反應檢測時，係由氫氣電極導流板導入氫氣，空氣電極導流板導入空氣，經過反應後產出水，再由空氣電極導流板排出；於逆反應檢測時，則係由空氣電極導流板導入水及空氣，經過反應後產出氫氣，再由空氣電極導流板導出。The operation of solid oxide fuel cells is mainly divided into two modes of operation: forward reaction and reverse reaction. When the solid oxide fuel cell is installed on the conventional bearing mechanism for positive reaction detection, hydrogen is introduced through the hydrogen electrode guide plate, and air is introduced into the air electrode guide plate. After the reaction, water is produced, and then discharged from the air electrode guide plate. ; When the reverse reaction is detected, water and air are introduced by the air electrode guide plate, and hydrogen is produced after the reaction, which is then exported by the air electrode guide plate.
由於固態氧化物燃料電池於工作的環境溫度是400℃以上的高溫，因此在進行逆反應檢測並自空氣電極導流板導入水及空氣時，因水會經過高溫汽化，而造成體積大幅膨脹，進而容易造成習用由氧化鋁之陶瓷所組成的空氣電極導流板發生破裂之情況。Since the working ambient temperature of the solid oxide fuel cell is a high temperature above 400°C, when the reverse reaction detection is performed and water and air are introduced from the air electrode guide plate, the water will undergo high temperature vaporization, resulting in a large volume expansion, and then It is easy to cause the conventional air electrode guide plate composed of alumina ceramics to crack.
當發生上述空氣電極導流板破裂的情況時，會增加檢測成本，且會連帶樣品(受檢測的固態氧化物燃料電池)破損，也會導致檢測的結果不準確。When the above-mentioned air electrode deflector is ruptured, the detection cost will be increased, and the sample (the tested solid oxide fuel cell) will be damaged, resulting in inaccurate detection results.
鑒於上述問題，本申請人認為，如能增加空氣電極導流板質地的延展性，能有效降低空氣電極導流板發生破裂的情況，進而可以減少檢測時的成本以及提升檢測結果的準確性。In view of the above problems, the applicant believes that if the ductility of the air electrode deflector can be increased, the rupture of the air electrode deflector can be effectively reduced, thereby reducing the cost of testing and improving the accuracy of testing results.
本發明之主要目的乃在於提供一種固態氧化物燃料電池檢測裝置之承載結構，其可增加空氣電極導流板質地的延展性，於逆反應檢測時，能有效降低空氣電極導流板發生破裂的情況，進而可以減少檢測固態氧化物燃料電池效能的成本。The main purpose of the present invention is to provide a support structure for a solid oxide fuel cell detection device, which can increase the ductility of the air electrode guide plate, and can effectively reduce the rupture of the air electrode guide plate during reverse reaction detection. , which in turn can reduce the cost of testing the performance of solid oxide fuel cells.
