摘要:

近年来,随着燃料电池功率的不断提升,氢气供给系统朝向带有氢循环的盲端阳极拓扑构型发展。然而,针对氢气供给和循环的测试系统研究明显滞后,尤其在氢气循环泵和引射器等核心部件的性能测试方面。本文研发了多功能燃料电池氢气供应系统测试平台,实现了对不同构型氢气循环方案的氢气供应系统的零部件测试和特性数据采集、离线标定等功能。平台通过模拟真实电堆的压降、氢气消耗及产水产热,消除了测试对真实电堆性能和寿命产生损耗而造成的额外成本。最后,基于该平台对150 kW燃料电池的氢气供应系统进行了阳极压力控制和阳极吹扫控制测试,验证了所开发测试平台能够针对不同负载满足相应测试需求。

Abstract:

In recent years, with the continuous enhancement of fuel cell power, hydrogen supply systems have been evolving towards blind-end anode topologies with hydrogen circulation. However, research on testing systems for hydrogen supply and circulation lags noticeably, particularly in the performance testing of core components such as hydrogen circulation pumps and injectors. Therefore, a multifunctional testing platform for fuel cell hydrogen supply systems is developed in this paper, enabling component testing, characteristic data acquisition, offline calibration, and other functionalities for hydrogen circulation systems with different configurations. The platform, by simulating the pressure drop, hydrogen consumption, and the production of water and heat in real fuel cells, mitigates the additional cost incurred by testing on the performance and lifespan of actual fuel cells. Ultimately, based on this platform, an anode pressure control and anode purge control test are conducted on the hydrogen supply system of a 150 kW fuel cell, verifying the capability of the developed testing platform to meet specific testing requirements for different loads.
