Development of Hydrogen Circulation System Test Platform for High-Power Fuel Cell

Abstract

The increasing demand for high-power fuel cell system pushes the improvements of each subsystem, and hydrogen circulation system is one of the key subsystems. Therefore, it is necessary to establish a test platform for hydrogen circulation subsystem with complete testing capabilities and reliability. However, the research on the hydrogen circulation system test system is obviously lagging, especially in the performance test of the core components of the hydrogen circulation pump and the ejector. This paper adopts the modular design idea, develops a complete and reliable comprehensive performance test platform for hydrogen circulation system, designs the corresponding closed-loop control strategy of pressure and temperature, and finally conducts test verification.
