ABSTRACT:
A fuel cell system for replacement of fuel gas includes a fuel cell having a fuel chamber, a fuel supply subsystem communicating with the fuel chamber of the fuel cell and a contact-type burner installed in the fuel supply subsystem for burning, with air, fuel derived from the fuel supply subsystem. At the time of start of operation of the fuel cell, in the operating state of the burner, a feed quantity of the fuel gas to be introduced into the burner is gradually increased while a feed quantity of the air to be introduced into the burner is decreased from 100% to 0% so that the air in the fuel chamber is replaced with the fuel gas. At the time of stop of operation of the fuel cell, in the operating state of the burner, the feed quantity of the fuel gas to be introduced into the burner is gradually decreased while the feed quantity of the air to be introduced into the burner is increased from 0% to 100% so that the fuel gas in the fuel chamber is replaced with the air.
