Abstract

PURPOSE:To increase the reliability of a system by constituting a deterioration detection means with a voltage output measuring line, temperature output measuring line, an evaluation system, flow rate controller and the like, and decreasing the utilization of reaction gases when voltage and temperature variations of each module cell which are generated according to the variation of the utilization of the reaction gases had positive correlation. CONSTITUTION:A fuel cell power generating system consists of a cell main body 1A comprising module cells 1 consisting of a plurality of cells. A voltage output measuring line 2, a temperature output measuring line 3, and an evaluation system 4 connected to these lines are installed in each module cell 1. A flow rate controller 6 is installed among the system 4, the cell 1, and a reaction gas supply line. When the voltage variation and the temperature variation of the cell 1 had positive correlation according to the utilization of the reaction gas, the utilization of the reaction gas is decreased. The deterioration of the cell main body 1A and the presence of a defective cell are easily detected and the reliability of operation is increased.
