Patent number: 7749623Abstract: A fuel cell is obtained, in which oxidation degradation of a catalyst in the cathode can be prevented even if a large volume of air instantaneously penetrates into the cell, and the fuel-cell characteristics also do not deteriorate even though starting-up, shutting-down and pausing operations are repeatedly performed. As a method of controlling a fuel cell system, hydrogen-containing fuel gas is supplied to the anode and oxidant gas is supplied to the cathode, an external load is connected between the anode and the cathode so that the fuel cell generates electric power, the external load is disconnected after the power generation, a resistor is connected between the anode and the cathode, supply of the oxidant gas is stopped, and then supply of the fuel gas is stopped after the potential at the cathode has dropped to equal to or lower than the potential at which hydrogen evolution starts, so as to pause the fuel cell.Type: GrantFiled: March 16, 2005Date of Patent: July 6, 2010Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hironori Kuriki, Hisatoshi Fukumoto, Takashi Nishimura, Hiroaki Urushibata, Hajimu Yoshiyasu
