The BP series testing system provides a basic, convenient, fast, and stable platform for performance evaluation and characterization testing of core materials and key components in PEM (Proton Exchange Membrane) electrolysis water hydrogen production. The series BP can achieve performance testing, sensitivity testing, lifespan assessment, and theoretical research of PEM electrolysis cells. Through a professionally developed operating software, the system can control, monitor, and display various parameters and operating conditions of the electrolysis cell in real-time, including water temperature, pressure, flow rate, voltage, current, and other parameters.
