Abstract
Description
Technical Field
[0001] This invention relates to new energy power generation equipment technology, specifically to a portable ammonia-hydrogen fuel cell system with a coupling testing device. Background Technology
[0002] Ammonia-hydrogen fuel cell technology, as an important innovative direction for hydrogen energy application systems, effectively overcomes the technical bottlenecks of traditional high-pressure gaseous hydrogen storage in terms of energy density (liquid ammonia volumetric energy density reaches 13.6 MJ·L⁻¹, 50% higher than liquid hydrogen) and safety (explosion limits 16%–25%, superior to hydrogen's 4%–76%) by using ammonia as a hydrogen energy carrier for fuel supply. Currently, this technology is still in the system integration and optimization stage. To meet the logistics analysis needs of ammonia-hydrogen fuel cell systems, it is necessary to construct an online monitoring system based on a multi-parameter sensor array. This system should acquire key parameters such as the composition and temperature gradient distribution of the H₂ / N₂ / NH₃ mixed gas in real time and establish a multi-scale energy accounting model. However, for the detection of gas components in ammonia-hydrogen fuel cells, existing ammonia-hydrogen fuel cell systems generally use chromatography for gas composition analysis. This method has limitations such as poor moisture resistance, single analytical components, and slow response. Furthermore, adding flow meters to ammonia-hydrogen fuel cells leads to low system integration and high cost, making it impossible to accurately and effectively detect and analyze various gases during the operation of the fuel cell system in real time.

Self-heating ammonia decomposition reactor; 10. First cooling device; 11. Desorption device; and 12. Fuel cell; The ammonia tank 8 is connected to the self-heating ammonia decomposition reactor 9 and provides ammonia gas to the self-heating ammonia decomposition reactor 9; the self-heating ammonia decomposition reactor 9 is connected to the desorption device 11 through the first cooling device 10; the desorption device 11 is then connected to the fuel cell 12; the outlet of the fuel cell 12 is connected to the self-heating ammonia decomposition reactor 9 and provides fuel to the self-heating ammonia decomposition reactor 9. A second interface b is provided between the desorption device 11 and the first cooling device 10, and a third interface c is provided between the desorption device 11 and the fuel cell 12; the second interface b and the third interface c are simultaneously connected to the flow guiding device 1; a fourth interface d is provided on the outlet of the fuel cell 12; the fourth interface d is connected to the water treatment device 3; the water treatment device 3 is also connected to the flow guiding device 1 and the flow detection device 4 respectively; the flow guiding module 1 is connected to the gas component analysis device 5; the flow guiding device 1, the flow detection device 4 and the gas component analysis device 5 are arranged close to each other and integrated in the same module; the bottom of the module integrating the flow guiding device 1, the flow detection device 4 and the gas component analysis device 5 is provided with casters and is detachably connected to the connected components.
[0018] The self-heating ammonia decomposition reactor 9 includes a combustion section and an ammonia decomposition section. The combustion section is used to burn fuel and supply the combustion gas to the ammonia decomposition section as a heat source for ammonia decomposition. The ammonia decomposition section includes an ammonia gas pipe and a flue gas pipe that are attached to each other. The ammonia gas pipe is connected to the ammonia tank 8. The flue gas pipe is connected to the combustion section. The outlet of the ammonia gas pipe is connected to the first cooling device 10. To improve the decomposition efficiency of ammonia, the ammonia gas pipe is filled with an ammonia decomposition catalyst. An electric heater is fixed on the ammonia gas pipe to provide an additional heat source. The ammonia gas in the ammonia tank 8 enters the self-heating ammonia decomposition reactor 9 and is decomposed into a high-temperature hydrogen-nitrogen mixture. The high-temperature hydrogen-nitrogen mixture is discharged through the ammonia gas pipe outlet of the self-heating ammonia decomposition reactor 9 and enters the first cooling module 10. The high-temperature hydrogen-nitrogen mixture is then... After being cooled to room temperature by the first cooling module 10, the ambient temperature hydrogen-nitrogen mixture enters the desorption device 11 to desorb residual ammonia. It then enters the fuel cell 12 to generate electricity. A gas-liquid separator 13 is externally connected to the gas outlet of the fuel cell 12. The gas discharged from the gas outlet of the fuel cell 12 enters the gas-liquid separator 13 for gas-liquid separation and to remove water vapor from the gas discharged after the fuel cell 12 generates electricity. Preferably, the gas-liquid separator 13 is connected to the combustion section. The gas separated by the gas-liquid separator, for example, the hydrogen and nitrogen remaining after removing water vapor from the fuel cell 12, enters the combustion section as fuel. The high-temperature gas generated by combustion provides heat to the ammonia in the ammonia pipeline and promotes its endothermic decomposition, thereby maintaining the reaction temperature of the self-heating ammonia decomposition reactor 9.
[0019] The flue gas duct has a first interface a at its outlet; the flue gas duct is connected to a second cooling device 2 through the first interface a; the second cooling device 2 is then connected to the water treatment device 3; the second cooling device 2 is a plate heat exchanger, with circulating water flowing on one side and high-temperature gas to be tested, i.e., heated combustion gas discharged from the flue gas duct, flowing on the other side; the plate heat exchanger is placed vertically, and the high-temperature gas enters from the top of the plate heat exchanger, undergoes heat exchange through the circulating water, and the heat of the high-temperature gas is carried away to reduce the gas temperature; the cooled combustion gas is discharged from the bottom of the plate heat exchanger and transported to the water treatment device 3; the second cooling device has a body The device features a small size and compact structure, which prevents moisture in the gas from accumulating in the heat exchanger and clogging the pipes after cooling, while also improving the cooling efficiency of the cooling device. After the gas from the combustion component is introduced into the second cooling device 2 and the water treatment device 3 for cooling and water absorption respectively, the gas is then introduced into the flow detection device 4 or the gas composition analysis device 5 to detect the gas flow rate and composition. By detecting the gas flow rate and composition, the combustion effect of the combustion part in the self-heating ammonia decomposition reactor 9 and the corresponding heating effect on ammonia can be analyzed. This allows for a preliminary analysis and judgment of the reaction effect in the self-heating ammonia decomposition reactor 9, achieving effective monitoring and real-time analysis of the ammonia decomposition effect.
[0020] The first cooling device 10 has a second interface b and is connected to the desorption device 11; the first cooling device 10 is connected to the flow guiding device 1 through the second interface b; the outlet of the desorption device 11 has a third interface c; the desorption device 11 is connected to the flow guiding device 1 through the third interface c; the flow guiding device 1 is then connected to the gas component analysis device 5; the gas component analysis device 5 includes, but is not limited to, a hydrogen concentration detector, a nitrogen concentration detector, an ammonia concentration detector, and a nitrogen oxide detector, and the gas component analysis principle adopted includes, but is not limited to, the principle of electrochemical sensor / infrared sensor / thermal conductivity sensor, which can be used to detect the concentration and content of each component in the mixed gas after moisture removal. The detection instruments are in parallel flow mode and each detection instrument is connected to a flow guiding device. Valves are provided to control the composition detection of gases entering the flow guiding device 1 from different paths and with different compositions. By guiding the decomposed gases before and after desorption into the gas composition analysis device 5 through the flow guiding device 1, the desorption effect of the desorption device 11 is verified. Similarly, the ammonia decomposition effect of the self-heating ammonia decomposition reactor 9 can also be further verified. Combined with the previous verification of the combustion effect, the ammonia decomposition effect in the self-heating ammonia decomposition reactor can be analyzed more accurately. Similarly, the gases entering and exiting the fuel cell 12 before and after power generation can also be detected and analyzed by the gas composition analysis device 5 and the flow detection device 4. By detecting the corresponding gas components and flow rates, the gas utilization rate of the fuel cell 12 is verified, and the operation of the fuel cell 12 can be judged and analyzed.
[0021] The gas outlet of the fuel cell 12 is connected to the water treatment device 3 via the fourth interface d. The water treatment device 3 consists of three parts: a water adsorption unit, a water weighing unit, and a heating unit. The water adsorption unit absorbs moisture from the measured gas flow, and the water weighing unit detects the flow rate of water adsorbed from the gas flow. The heating unit is used to heat and activate the water adsorption unit to achieve water adsorption unit recycling. The water adsorption unit of the water treatment device 3 is divided into separately arranged A / B water columns. The water columns are stainless steel tube structures, and each water column is filled with water adsorbent to adsorb water in the mixed gas. Each water column has a gas inlet and a gas outlet on both sides to introduce the gas into the corresponding outlet. The water treatment device 3 purifies residual water in the gas by adsorption within a water column; the heating unit of the water treatment device 3 is an electric heating device with heat preservation effect, and the heating unit consists of a heating wire and heat preservation material; the heating unit tightly wraps the water adsorption unit and is detachably connected to the water adsorption unit, enabling rapid disassembly of the heating unit; the heating temperature of the heating unit is between 200-400℃; the water weighing unit of the water treatment module 3 is used to calculate the increase in water mass of the adsorption unit per unit time, and then calculate the flow rate of water in the mixed gas; at the same time, the water adsorption unit is also connected to an external nitrogen source; the corresponding water column in the water adsorption unit is purged by the external nitrogen source to desorb and regenerate the corresponding water column.
[0022] When the water treatment device 3 is in the adsorption state, the heating unit is not working. The water adsorption unit absorbs the moisture in the gas to be tested and introduces the remaining dehydrated gas through the water treatment device 3 into the flow detection device 4 or through the flow guiding module 1 into the gas component analysis device 5. The flow rate of water in the mixed gas can be measured by detecting the mass change of the water column before and after adsorption through the water weighing unit. When the water treatment device 3 is in the desorption state, nitrogen enters through the inlet of the water adsorption unit. The heating unit works to conduct heat to the water adsorption unit and nitrogen. The heated high-temperature nitrogen purges the water adsorption unit and discharges it through the vent to remove the moisture adsorbed during the adsorption process. The outlet gas temperature of the water adsorption unit (i.e., the nitrogen discharged from the water adsorption unit) is between 100-300°C. ℃; to improve the purging effect of the water adsorption unit; by using two independently operating water columns AB and combining nitrogen, water weighing unit and heating unit to effectively control the water removal effect of the water treatment device; greatly improve the water absorption effect of the water treatment device; thereby improving the analysis accuracy and detection efficiency of the subsequent flow detection module and gas component analysis module.
[0023] The flow detection device 4 consists of a vortex flow meter and related valves, and can be used to detect the total flow rate of a mixed gas that has been adsorbed by water and contains no moisture. The inlet of the flow detection device 4 is connected to the outlet of the water treatment device 3, and the inlet of the flow detection device 4 is also connected to the flow guiding device 1, which can realize real-time measurement of the flow rate of each gas component during the operation of the fuel cell and corresponding components.
[0024] The flow guiding device 1, the flow detection device 4, and the gas component analysis device 5 are arranged close together; the water treatment device 3 and the second cooling device 2 are arranged separately; the flow guiding device 1, the flow detection device 4, and the gas component analysis device 5 together form a moving module; universal wheels are provided below the moving module, the water treatment device 3, and the second cooling device 2; by moving the flow guiding device, the flow detection device, and the gas component analysis device in a centralized manner, the effective integration and rapid installation between components are improved; and the convenient movement of the system is realized.
[0025] Based on the flow rate of the gas to be tested in different specifications of ammonia-hydrogen fuel cell systems, relevant modules in the fuel cell system can be adjusted to achieve structural matching. For example, the first outlet a corresponds to the high-temperature mixed gas containing water vapor in the ammonia-hydrogen fuel cell system, mainly composed of water, oxygen, nitrogen, ammonia, hydrogen, and nitrogen oxides; the second outlet b corresponds to the ammonia decomposition product gas after cooling to room temperature, mainly composed of nitrogen, hydrogen, and a small amount of ammonia; the third outlet c corresponds to the decomposition gas after passing through the ammonia removal module, mainly composed of nitrogen and hydrogen, and it needs to be confirmed whether the decomposition gas after passing through the ammonia removal module contains ammonia; the fourth outlet d corresponds to the mixed gas at the fuel cell outlet, mainly composed of water, hydrogen, and nitrogen. This achieves real-time monitoring of gases emitted from different locations and components in the ammonia-hydrogen fuel cell system, enabling indirect analysis and detection of processes such as ammonia decomposition and fuel cell power generation. This greatly improves the diversity of the testing system for detecting different gases, while also minimizing the impact of humidity on the gas, thus improving testing accuracy.
[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
