Abstract

PURPOSE:To early, accurately detect defective cells by comparing the output voltage in steady operation with the output voltage produced when a mixed gas having low oxygen concentration is supplied to an oxidizing agent electrode for judging defective cells. CONSTITUTION:The output voltage of each cell and each cell block of a cell stack 1 is measured during operation to obtain output voltage V1. A valve 8 of an inert gas supply line 6 is opened and a mixed gas of air and an inert gas, in which oxygen gas concentration is reduced than that in the air, is supplied to an oxidizing agent electrode of the cell stack by controlling the flow rate so that the previously set mixed ratio of air and inert gas is obtained, and then the output voltage is measured to obtain output voltage V2. The output voltage V1 is compared with the output voltage V2 to obtain output voltage difference DELTAV. If the output voltage difference DELTAV exceeds the reference value, it shows that an excess electrolyte penetrates in the catalyst layer of the oxidizing agent electrode in the cell or cell block cell, and that cell is judged as a defective cell.
