Fuel cell internal resistance is the key data of fuel cell power generation performance, hydrogen fuel cell is a nonlinear device, its internal impedance will change with the change of operating conditions (such as temperature and current density). By integrating the EIS impedance analyzer, the Bette high power reactor test stand can monitor, evaluate and analyze the electrical performance data of fuel cells under different operating conditions such as temperature, flow rate and current density.
The high-power EIS tester has a test frequency range of 1Hz (0.1Hz) ~10kHz, comprehensive data, can simultaneously collect EIS from each battery, each channel is equipped with an advanced analog-to-digital converter, high sampling rate, and can realize simultaneous sampling and processing of multiple channels (up to 20CH). Enables fast and precise diagnostic testing and is ideal for fuel cell (stack) downline testing.
