The performance of each single cell in the fuel cell stack is an important factor influencing the performance of the fuel cell stack, and the voltage of each single cell should be kept consistent when the fuel cell is in normal operation. If the voltage of a local single cell is seriously lower than the integral average voltage due to liquid water blockage in a flow channel of the local single cell, shortage of fuel/oxidant, poor manufacturing/assembling consistency and the like, the operation of the fuel cell must be stopped in time to protect the fuel cell stack, so that the accurate monitoring of the voltage of the single cell of each cell of the fuel cell stack is an important measure for ensuring the safe and reliable operation of the fuel cell stack.
