<P>PROBLEM TO BE SOLVED: To make a fuel cell obtain a system temperature by a logical calculation unit by the detection of an open-circuit voltage of a membrane electrode conjugant. <P>SOLUTION: The feedback type fuel cell is composed of a fuel cell, a circuit mechanism and a logical calculation unit. The fuel cell is electrically connected with the circuit mechanism, and furthermore, the circuit mechanism has a circuit of an electric power integration mechanism and an opening voltage detecting means. The electric power mechanism is electrically connected with a first membrane electrode joint body and also supplies a power output, and the opening voltage detecting means is electrically connected with a second membrane electrode jointed body and the logical calculation means is electrically connected with the circuit mechanism, and furthermore, the logical calculation means has a temperature conjugant means which feeds back an opening voltage value of the second membrane electrode determination by the opening voltage detecting means and determines a corresponding temperature value. <P>COPYRIGHT: (C)2007,JPO&INPIT |
