The connector using parallel straight channels is simple in structure and easy to process, but the connector only has the functions of conducting electricity and providing channels for gas, has limited functions, and causes uneven gas distribution, thereby affecting the overall performance and thermo-mechanical stability of the battery.
At present, research on the connecting piece mainly focuses on improving the uneven gas distribution problem and selecting heat conducting/electric conducting materials, and the development of other functions of the connecting piece is not involved.

In order to adapt to the working environment of the battery, the improved connecting piece is made of high-temperature-resistant metal or alloy.
The invention also provides a flat SOFC battery stack comprising the improved connecting piece. And assembling the connecting piece and the battery PEN layer into a battery unit, and stacking layer by layer to assemble a battery stack.
In the working process of the cell stack, ammonia gas/hydrogen gas/nitrogen gas/water vapor mixed gas with a certain temperature is introduced at the gas inlet 2-1 of the connecting piece at a speed of not less than 1m/s, the ammonia gas in the mixed gas enters a catalyst Ni coating arranged at the position 3-6 of the heat absorption surface through diffusion, and is cracked and absorbed under the action of the catalyst Ni to absorb heat and absorb reaction heat from the cell, so that the cell stack is rapidly cooled; the cracked mixed gas flows to a flow area 3-3 through an air hole 3-2, and the mixed gas flows in the flow area 3-3 and diffuses into a PEN layer porous electrode to perform electrochemical reaction and generate electric energy; the reacted gas flows along the flow area 3-3 to the gas outlet 2-5 of the connecting piece and flows out of the connecting piece.
Due to the different heat generation and cell performance of the cells at different voltages, there will be different temperature distributions and current densities. In order for the improved coupling of the present invention to function adequately at different operating conditions, the optimum operating conditions of the inlet gas at different voltages are discussed herein. Taking the current density as a parameter for representing the performance of the battery; the maximum temperature difference is taken as a characteristic parameter of the battery temperature distribution. The gas introduced consists of 4 components: h2、 NH3、H2O、N2. So define H2And NH3In a total molar fraction of 0.95, N2And H2The total molar fraction of O was 0.05.
The temperature profile of the cell when using the improved connector of the invention is related to the inlet gas condition parameters (inlet velocity of the gas, ratio of components in the gas). The maximum value of the cell when the inlet velocity was varied from 1m/s to 3m/s and the total molar fraction of hydrogen was varied from 0.80 to 0.85 at voltages of 0.8V and 0.9VThe temperature differences are shown in fig. 4 and 5; the maximum current density is shown in fig. 6 and 7. The simulation was implemented using COMSOL commercial software. FIGS. 4 and 5 illustrate that the most uniform temperature distribution of the cell occurs at a gas velocity of 1m/s, but at a voltage of 0.8V, the most uniform temperature distribution was achieved at a hydrogen mole fraction of 0.83, and the maximum temperature difference was 6.23K; the working condition of the most uniform temperature distribution is obtained when the hydrogen mole fraction is 0.85 under the voltage of 0.9V, and the maximum temperature difference is 31.16K. FIGS. 6 and 7 show that the maximum current densities obtained at a velocity of 1m/s and a hydrogen mole fraction of 0.85 were 2619.4A/m, respectively2And 1368.7A/m2。
To illustrate the advantages of the improved connectors of the present invention, the performance and temperature profile of SOFC units thermally managed with excess air from the cell cathode using currently available connectors (configuration shown in fig. 1) were separately modeled and compared to the case of using the improved connectors of the present invention. By integrating the battery performance and the temperature distribution condition, the inlet working condition adopts the working condition when the current density is maximum: the gas velocity was 1m/s, and the hydrogen mole fraction was 0.85 (ammonia gas 0.1, remaining 0.5 from N)2And H2O composition). The other working condition parameters are the same as those of the traditional connecting piece (the working voltage of the two is 0.8V, and the inlet gas temperature is 923K).
The results are shown in FIGS. 8 and 9: when the current commonly used connecting piece is adopted and the excess air (5 times of air quantity, the speed is 5m/s) of the cathode of the battery is used for carrying out heat management, the maximum temperature difference of the battery along the length direction is 26.7K, and the output current density is 2310A/m2(ii) a When the improved connecting piece is adopted, the maximum temperature difference of the battery along the length direction is 15K, and the output current density is 2619.4A/m2Compared with an air cooling method, the maximum temperature difference in the battery is reduced by 3.98K, and the output current density is improved by 10.94%.
The results prove that the improved connecting piece not only can meet the three main functions of the conventional connecting piece (connecting the anode and the cathode of the adjacent single cell, conducting electrons, providing a flow channel for reactants and products), but also can carry out thermal management on the SOFC cell stack, effectively improve the nonuniformity of temperature distribution in the cell stack, reduce the maximum temperature difference in the cell stack and improve the output performance of the cell stack.
