A method for activating a fuel battery system by which the anode is infal libly prevented from being degraded by oxidation since reforming is infallib ly performed from an early stage. The fuel battery system comprises a reform er having a reforming catalyst layer for producing a hydrogen-containing gas by reforming a hydrocarbon fuel and a high-temperature fuel cell for genera ting electric power by using the gas. The method includes the steps of (a) p reviously detecting the temperature condition of the catalyst layer enabling the reforming of the fuel the flow of which is lower than that after the ac tivation and the temperature condition of the catalyst layer enabling the re forming of the fuel of the flow after the activation, (b) increasing the tem perature of the catalyst layer while measuring the temperature, (c) determin ing the fuel flow at which the catalyst layer is capable of reforming the ga s when the temperature is measured by comparing the measured temperature wit h at least one of the two temperature conditions, (d) supplying the fuel of the determined flow enabling the reforming to the catalyst layer if the dete rmined flow exceeds the present flow, reforming the fuel gas, supplying the reformed gas to the fuel cell anode, and repeating steps (c), (d) until the flow of the fuel gas supplied to the catalyst layer reaches the flow after t he activation. A fuel battery system preferable to thus method is also discl osed. |
