Abstract

PURPOSE:To detect surely a deteriorated unit cell out of generating cells by comparing the difference of the first degital quantity and the delayed second digital quantity of a voltage of a fuel battery cell with a prescribed value to detect the voltage drop. CONSTITUTION:A voltage drop value of a generating cell 1 comprising laminated unit cells in a given time is detected with a voltage drop detecting circuit 2. The detected value is divided to the first digital quantity passed through an AD converter 6 and to the second digital quantity through a delay circiut 7, and fed to a comparator 9, a difference of both digital quantities is determined, and compared with a prescribed value, and the voltage is detected after and before the voltage drop occurres due to the deterioration of any unit cell. By this method, the ordinal deterioration of an entire generating cell and of specific unit cell can be detected surely with a simple constitution.
