Abstract
Description
Technical Field
[0001] The utility model relates to the field of fuel cells, in particular to an intake air integration module for a dual-stack fuel cell system. Background Art
[0002] A fuel cell power generation device is a clean, efficient and low-noise power generation device, which is widely used in vehicles, aerospace and underwater power equipment. When the fuel cell power generation device works, it needs to continuously supply hydrogen and oxygen (air) from the outside. The two enter the fuel cell stack through the intake air module and continuously react to generate electric energy. The design of the intake air module affects the working efficiency and stability of the fuel cell power generation device. A reasonable intake air module is simple and reliable, can provide sufficient air volume, and is also convenient for the control system to adjust it. There is sufficient space to install sensors and other adjustment devices, so that the fuel cell power generation device operates stably and efficiently, and can be monitored and adjusted. For different fuel cell power generation devices, the design and layout of the intake air module are variable. With the increasing demand for power in the application scenario, a single fuel cell can no longer meet the power demand, so a dual-stack fuel cell appears. The dual-stack fuel cell needs to meet the same pressure and flow rate. Therefore, designing a reasonable intake air module for the dual-stack fuel cell system is crucial for the operating efficiency and stability of the fuel cell power generation device. Summary of the Invention
[0003] The utility model is proposed to solve the above-mentioned deficiencies existing in the prior art, and provides an intake air integration module with a simple structure, ingenious design, reasonable layout, which can simultaneously provide sufficient air and hydrogen for a dual-stack fuel cell, and can monitor various parameters of the supplied gas.
[0004] The technical solution of the utility model is: an intake air integration module for a dual-stack fuel cell system, characterized in that: the intake air integration module includes an integrated housing 1, one side of the integrated housing 1 is connected with an air inlet joint 2 and a hydrogen inlet manifold 3. The air inlet joint 2 is communicated with an air inlet 4 opened on the side plate of the integrated housing 1. The air inlet 4 is communicated with two air outlets 5 opened on another side plate of the integrated housing 1 through an air pipeline. The hydrogen inlet manifold 3 is communicated with a hydrogen inlet 6 opened on the side plate of the integrated housing 1. The hydrogen inlet 6 is communicated with two hydrogen outlets 7 opened on another side plate of the integrated housing 1 through a hydrogen pipeline.
[0005] A throttle valve 8, a temperature sensor 9 and a pressure sensor 10 are arranged on the air joint 2. A branch pipeline 11 and a pressure sensor 10 are arranged on the hydrogen inlet manifold 3. A temperature sensor 9 communicated with the hydrogen pipeline is arranged on the side wall of the integrated housing 1.
[0006] At the top of the integrated housing 1, there are an air pipeline blind plate 12 and a hydrogen pipeline blind plate 13. The air pipeline blind plate 12 is located above the air pipeline, and the hydrogen pipeline blind plate 13 is located above the hydrogen pipeline.
[0007] Compared with the prior art, the utility model has the following advantages:
[0008] The intake air integration module of the double-stack fuel cell system with this structural form has a simple structure, ingenious design, and reasonable layout. Aiming at the situation that the traditional intake air module cannot adapt to the double-stack fuel cell, a special structure is designed. The air pipeline and hydrogen pipeline inside it are both of the "one-in and two-out" structure. Therefore, it can provide air and hydrogen for two fuel cell systems (i.e., the double-stack fuel cell system) simultaneously. And it is also equipped with a pressure sensor and a temperature sensor for each pipeline, so that the staff can control the working state of the double-stack fuel cell system in real time. Moreover, the manufacturing process of this intake air integration module is simple and the manufacturing cost is low. Therefore, it can be said that it has multiple advantages and is especially suitable for popularization and application in this field, and its market prospect is very broad.
