Name: Fuel Cell Bipolar Plate and Carbon Paper Resistance Tester
Equipment Type: Proton-Exchange Membrane Fuel Cell Bipolar Plate and Carbon Paper Resistance Tester
Product Code: XN-ST2921B
Brand: Xnergy
Product Introduction:
The XN-ST2921B is a professional integrated resistance-testing system for proton-exchange membrane fuel-cell bipolar plates, carbon paper, diffusion layers, and related components. It combines four-probe and four-terminal measurement methods with an automatic pressure console, thickness gauge, color display, and PC measurement software.
The four-probe method is used for in-plane resistivity measurement, while the four-terminal method is used for through-plane resistance and contact-resistance measurement. The system can synchronously display resistance, pressure, and thickness, and can generate resistance-pressure, resistivity-pressure, and contact-resistance-pressure reports and curves.
Key Features:
Four-probe and four-terminal measurement in one system
Automatic pressure control with a minimum pressure step of 0.05 MPa
Pressure range from 0.05 MPa to 4 MPa
Gold-plated copper electrodes and dedicated fuel-cell test bench
Color screen with synchronous resistance, pressure, and thickness display
PC software for measurement control, data viewing, editing, saving, printing, and history queries
Automatic stepped multi-pressure testing and curve fitting
Suitable for bipolar plates, carbon paper, diffusion layers, and fuel-cell components
