1.2 Product Overview

The GR-FCTS series fuel cell test bench is designed to provide an accurate and reliable testing platform for fuel cell stacks. This test bench has undergone multiple upgrades and optimizations based on the performance of existing products in the industry. Through hardware architecture optimization and precise software algorithms, as well as the identification of nonlinear system parameters and multivariable optimization control technology for fuel cells, it achieves precise and controllable operating parameters. Simulation models for micrometer/millimeter-level liquid water transfer and impedance analysis are established based on data mining and parameter identification technology, providing users with battery lifecycle data service analysis.

This test bench consists of a gas supply unit, pressure control unit, temperature adjustment unit, humidity adjustment unit, PLC acquisition and control unit, human-machine operation unit, and safety monitoring unit. It uses the company's self-developed system testing software, which can meet the testing functions of polarization curve testing, steady-state operation, dynamic response testing, activation testing, sensitivity testing, and durability testing for fuel cells. It is suitable for the research and testing of fuel cell single cells, short stacks, complete stacks, components, and material levels.
