<P>PROBLEM TO BE SOLVED: To estimate the temperature of a fuel cell based on the temperature of cooling water delivered from the fuel cell and ambient temperature, and decide whether heating of the fuel cell is necessary or not. <P>SOLUTION: A fuel cell system controller equipped with a cooling means 3 cooling moisture exhausted from the fuel cell 1 in the downstream part of a heating means 11 heating the moisture in a circulation passage 37 through which the moisture is circulated to the fuel cell 1 is equipped with a first temperature detecting means 32 detecting the ambient temperature, a second temperature detecting means 30 detecting the temperature of moisture in an outlet of the fuel cell 1, a third temperature detecting means 33 detecting the temperature of moisture in an inlet of the cooling means 3, and the temperature of the fuel cell is estimated based on the temperature difference between the temperature detected with the second temperature detecting means 30 and the temperature detected with the third temperature detecting means 33 and the heat discharge of the fuel cell 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
