Abstract
A power supply system, a fuel cell power generation performance detection device and a control method thereof are provided. The fuel cell has a rated output voltage and an internal resistance having a preset resistance value. The detection device includes a test resistor, a first test switch, a current detection unit and a control unit. The control unit controls the first test switch and the current detection unit to send a first control signal to selectively turn on the first test switch. When the first test switch is turned on, the fuel cell, the test resistor, the first test switch and the current detection unit define a test loop. The current detection unit detects a test current passing through the test loop. The control unit obtains a real-time resistance value of the internal resistance based on the test current to evaluate the power generation performance of the fuel cell.
