As with other fuel cells, SOFC also needs to make battery heaps to increase voltage and power output. Since there is no liquid component. SOFC can make a variety of configurations. At present, there are two main types of SOFC, namely tube and plate.The plate SOFC appeared in the early 1960s, the disadvantage of this configuration is that the gas seal is difficult. Affected by the technical conditions, it is difficult to manufacture a large area and small thickness, and the tube design is very good to solve the seal. And thin layer structure problems.
1, tube SOFC
1.1 single battery
The most significant advantage of SOFC tube design is to eliminate high temperature gas density issues. The disadvantage of the tube design is that the current has a long path, and the performance of SOFC is limited. Japan's Mitsubishi Heavy Industries, the UK's Keele University, etc. With advanced tube SOFC design.
1.2 battery stack
The AES SOFC design has no chemical and material interference between the single battery and the previous layer and the previous layer, and the support tube is sealed, and each battery does not need to be sealed. The fuel gas flows consistent with the oxidizing gas. The anode and cathode exhaust gas contains unreacted reactants. Mixed, combustion fever, for oxidizing flow preheating and driven turbine power generation.
2, board SOFC
At the same time as the SOFC development of the tube structure, the plate structure and single chip design have also been developed. The plate structure, also known as the bipolar structure, is a conventional configuration with the PA FC and MCFC, which can form a simple electrical connection between the battery. Therefore, the ohmic loss is less than the tube-type design, which has a superior battery heap performance. And a higher power density. Compared with other configuration SOFC, the component manufacturing and assembly of the board SOFC is relatively simple, and the low-cost preparation method such as screen printing and casting, and the battery pack is the same as other fuel cells.
The disadvantage of the plate design is that the gas seal is required, which requires the interface thermal stress of different materials. In the high-voltage battery stack, the phenomenon of unevenness is prone to stress, so the difficulty of high pressure sealing is very large, and the thermal stress between the different batteries and the material interface will reduce its mechanical properties, so thermoset is very The important nature is compared to tubular design, and the board design is dominated in power density and efficiency, but many research institutions have gathered the development of board design because of their internal technical issues.
