Embodiment

[0034] like figure 1 Shown, a fuel cell air supply subsystem matching test method based on stack simulator, the method includes the following steps:

[0035] Step 01: Build the air supply subsystem of the fuel cell, and connect the key components of the air subsystem such as the air compressor, humidifier, and back pressure valve to the pre-set air subsystem circuits. These circuits can be: ①General Air supply and humidification circuit; ② circuit with air heating; ③ circuit with local humidification circuit; ④ circuit with idle exhaust decompression; ⑤ circuit with exhaust gas recirculation. In this embodiment, ① a conventional air supply and humidification circuit is adopted.

[0036] Step 02: Build the stack cathode simulator and perform calibration to simulate the fuel cell stack.

Abstract

The invention relates to a stack simulator-based matching test method for a fuel battery air supply subsystem. The method comprises the following steps: (1) building the fuel battery air supply subsystem; (2) building a stack cathode simulator, and calibrating the stack cathode simulator to simulate a fuel battery stack; (3) connecting the fuel battery air supply subsystem into the stack cathode simulator to form a working loop; (4) under a working condition, loading virtual power to the stack cathode simulator and operating the working loop in the step (3), wherein the virtual power is equal to the power of the fuel battery stack under a corresponding working condition; (5) under different working conditions, measuring key parameters in the cathode simulator and the air supply subsystem, and judging whether the fuel battery air supply subsystem is matched with the fuel battery stack or not. Compared with the prior art, the stack simulator-based matching test method disclosed by the invention is simple, feasible, wide in application range and high in practicability, and can perform independent and decoupling matching test on the fuel battery air supply subsystem.

Description

technical field [0001] The invention relates to a fuel cell engine matching test method, in particular to a fuel cell air supply subsystem matching test method based on a stack simulator. Background technique [0002] At present, most of the fuel cell engine test equipment developed by domestic companies such as Ji University, Tsinghua University, Wuhan University of Technology and others are mainly aimed at the performance test of fuel cell engines. During the test process, there is a lack of relevant test means, equipment and method support. Moreover, during the development and testing process, subsystems such as water and heat management, air supply, and hydrogen supply need to work simultaneously and are tightly coupled together, which cannot be independently verified. Increased the complexity and difficulty of the test process, making the components, subsystems, and control algorithms that have not been fully verified due to the fuel cell engine's "gas-water-electricit...
