ABSTRACT:
There is provided a method for stopping power generation of fuel cell system including: a fuel cell having a fuel electrode and an oxidizer electrode; a fuel container; and a fuel flow path for supplying a fuel from the fuel container to the fuel cell, which enables suppression of a pressure difference between the fuel electrode and the oxidizer electrode during a stop state of an operation of the fuel cell, the method including the steps of, during the stop state of the operation of the fuel cell: stopping supply of the fuel from the fuel container to the fuel cell; consuming a residual fuel in the fuel flow path by short-circuiting the fuel electrode and the oxidizer electrode or connecting a load between the fuel electrode and the oxidizer electrode; and opening the fuel flow path to the atmosphere.
