Abstract
A fuel cell system is disclosed in which the oxidative degradation of an anode of a fuel cell during an operation stop period is restrained.The fuel cell system (39) of the invention comprises a fuel cell (1) configured to generate electric power by use of hydrogen contained in a fuel gas supplied to an anode (1a) and oxygen contained in an oxidizing gas supplied to a cathode (1c); and a combustor (4) configured to combust flammable gas, and is formed such that after stopping the power generation, the flammable gas is introduced into and kept in the cathode (1c) and when discharging the flammable gas from the cathode (1c), the flammable gas is combusted by the combustor (4).
