Description
本發明是有關高效率燃料電池發電模組，尤指一種可回收剩餘燃料並減少低效率的燃燒反應，以有效提昇燃料使用率及整體發電效率的燃料電池發電模組。 The invention relates to a high-efficiency fuel cell power generation module, in particular to a fuel cell power generation module capable of recovering surplus fuel and reducing inefficient combustion reaction, thereby effectively improving fuel utilization rate and overall power generation efficiency.
燃料電池按工作溫度可分為高溫型與低溫型兩類。由於高溫型燃料電池具有較高效率、可以直接向陽極通入甲烷等燃料氣體、不需要使用貴金屬電極催化劑等低溫型無法比擬的優勢，因此近年來高溫燃料電池的發展逐漸受到矚目。為了追求更高更穩定的發電性能，各國在燃料電池電解質、電極催化、聯接板等電池材料與電池動力學及反應機構方面都投入了大量人力物力進行研究，並且進行系統測試。 Fuel cells can be classified into high temperature type and low temperature type according to working temperature. In recent years, the development of high-temperature fuel cells has attracted attention because of the high efficiency of high-temperature fuel cells, the ability to directly introduce fuel gas such as methane into the anode, and the incomparable advantages of low-temperature types such as noble metal electrode catalysts. In order to pursue higher and more stable power generation performance, countries have invested a lot of manpower and resources in fuel cell electrolytes, electrode catalysis, connecting plates and other battery materials and battery dynamics and reaction mechanisms, and conducted system tests.
一般的高溫燃料電池發電系統乃利用富氫燃料進行電化學反應以產生電能，而未進行電化學反應之殘餘燃料將導入燃燒器進行燃燒反應，以提升尾氣之熱能，並以其熱能提供整個系統運作，但當系統產生過多的熱無法消除時(即殘餘燃料過多進到燃燒器與電池運轉過程產生的高熱無法排除時)，系統在極高溫度下之操作，會使電池的燒毀機率增加，導致系統運作之風險增加。而高溫燃料電池因需加熱至高溫之環境(700~800℃)以上，因此很多熱工組件皆係整合成單一元件，因此會產生內部重組觸媒無法更換之問題。 A typical high-temperature fuel cell power generation system uses a hydrogen-rich fuel for electrochemical reaction to generate electrical energy, and a residual fuel that is not subjected to an electrochemical reaction is introduced into a burner for combustion reaction to enhance the thermal energy of the exhaust gas and provide the entire system with its thermal energy. Operation, but when the system generates too much heat to eliminate (ie, when the residual fuel enters the burner and the high heat generated by the battery operation cannot be eliminated), the operation of the system at extremely high temperatures will increase the probability of burning the battery. The risk of causing the system to operate increases. High-temperature fuel cells need to be heated to a high temperature environment (700~800 °C), so many thermal components are integrated into a single component, so there is a problem that the internal recombination catalyst cannot be replaced.
在高溫型燃料電池的領域中，如何作好熱能管理與燃料回收的工作，對於燃料電池的發電效率具有決定性的影響。而高效率燃料電池發電模組一般可以運用回收機制將大部分未燃燒的燃料送回進料處，調控燃料進到觸媒式燃燒器之比例，以維持所需溫度，因此過低燃料沒有熄火問題。 In the field of high-temperature fuel cells, how to do thermal energy management and fuel recovery has a decisive influence on the power generation efficiency of fuel cells. High-efficiency fuel cell power generation modules can generally use a recovery mechanism to return most of the unburned fuel back to the feed, and regulate the proportion of fuel entering the catalytic converter to maintain the required temperature, so the fuel is too low. problem.
美國專利US 2010/0136378 A1係為一燃燒器與重組器整合式之設計，其燃燒室雖能避免氫氣回火，但若燃料處於貧油區時，則易使火焰熄火導致系統無法運作。 U.S. Patent No. 2010/0136378 A1 is an integrated design of a burner and a recombiner. Although the combustion chamber can avoid hydrogen tempering, if the fuel is in a lean area, the flame is extinguished and the system cannot be operated.
美國專利US 7,156,886 B2為一燃燒器與重組器整合式之設計，其設計乃是將燃燒器與重組器直接堆疊而成，燃燒器位於重組器之下方，以其燃燒後之尾氣提供熱能供重組器進行燃料重組，此種設計的燃燒器及重組器所產生之熱散失極大，熱能管理方面有很大改善的空間。 U.S. Patent No. 7,156,886 B2 is an integrated design of a burner and a recombiner. The design is to directly stack the burner and the recombiner. The burner is located below the recombiner and provides heat for recombination with the exhaust gas after combustion. The fuel is reorganized, and the heat generated by the burner and the recombiner of this design is greatly dissipated, and there is much room for improvement in thermal energy management.
中華民國專利公告第M501659號「燃料電池系統」新型專利案第3圖中，揭露了包含有一熱交換器及一尾燃器的燃料電池裝置，該熱交換器與尾燃器依序連接於一光觸媒重組器之尾熱入口與一燃料電池之尾熱出口之間，而空氣先通過熱交換器再進入燃料電池之空氣入口，燃料電池反應後剩餘的氣體將先進入尾燃器，透過尾燃器將剩餘氣體進行燃燒反應後，加熱後的氣體先進入熱交換器，使通過熱交換器的空氣先預熱後再進入燃料電池，接著加熱後的氣體再通過尾熱入口進入光觸媒重組器，以提供光觸媒重組器反應時所需的熱能。 In the third example of the new patent of the "Fuel Cell System" of the Republic of China Patent No. M501659, a fuel cell device including a heat exchanger and a tail burner is disclosed. The heat exchanger and the tail burner are sequentially connected to each other. The heat inlet of the photocatalyst recombiner is between the hot inlet of a fuel cell and the tail end of a fuel cell, and the air first passes through the heat exchanger and then enters the air inlet of the fuel cell. After the reaction of the fuel cell, the remaining gas will first enter the tail gas burner and pass through the tail gas. After the remaining gas is subjected to a combustion reaction, the heated gas first enters the heat exchanger, so that the air passing through the heat exchanger is preheated before entering the fuel cell, and then the heated gas enters the photocatalyst recombiner through the tail heat inlet. To provide the thermal energy required for the photocatalyst recombiner reaction.
上述結構雖能利用尾燃器來將剩餘氣體再進行燃燒反應以提供更多熱能，而可預熱空氣及提供光觸媒重組器所需的熱能，以達到節 省能源損耗及提高產能效率的目的；但在實際應用上，該剩餘氣體並不一定能完全滿足尾燃器燃燒反應之所需(可能過多或不足)，單純地將剩餘氣體導入尾燃器燃燒，所能產生的電效率增進極為有限，因此，針對燃料電池各組件的排列規劃上仍有極大的改進空間。 Although the above structure can utilize the tail gas burner to re-combust the remaining gas to provide more heat energy, the air can be preheated and the heat energy required for the photocatalyst recombinator can be provided to reach the section. The purpose of saving energy consumption and improving productivity; however, in practical applications, the residual gas may not fully meet the requirements of the combustion reaction of the tail burner (may be excessive or insufficient), and simply introduce the remaining gas into the exhaust burner for combustion. The increase in electrical efficiency that can be produced is extremely limited. Therefore, there is still much room for improvement in the arrangement of fuel cell components.
有鑑於習見燃料電池之各組件的排列規劃及熱能與燃料回收再利用機制有上述缺點，發明人乃針對該些缺點研究改進之道，終於有本發明產生。 In view of the above-mentioned shortcomings of the arrangement of components of the fuel cell and the thermal energy and fuel recycling mechanism, the inventors have made research on the improvement of these shortcomings, and finally the present invention has been produced.
