PROBLEM TO BE SOLVED: To lengthen the service life of a fuel cell. SOLUTION: In a fuel cell power generation system having a fuel cell which is comprised of an anode having a supplying opening and exhaust opening of a fuel gas including hydrogen, a cathode having a supplying opening and exhaust opening of an oxidizer gas containing oxygen, and an electrolyte which intervenes between the anode and the cathodes; a cathode circulating line connecting the exhaust opening of the cathode with the supplying opening of the cathode; and a cathode blower equipped in the cathode circulating line, if an internal temperature detected of the above fuel ell reaches a predetermined value; the rate of a cathode circulation flow which flows in the above cathode circulation line will be increased. |
