FUEL CELL SYSTEM

PROBLEM TO BE SOLVED: To enhance certainty for carrying out initialization of data of a storage element of a new substrate, in case of changing of the substrate. SOLUTION: The fuel cell system 120 includes, on the substrate 121, a storage element 101, a battery 103 for battery backup of the storage element 101, a button 104 for indicating the initial input time, and a microcomputer 102. Since the microcomputer 102 is structured so as to initialize data of the storage element 101 as the button 104 is operated, as long as an operator who exchanges the substrate 121 of the fuel battery system 120 keeps a rule (a procedure) to operate the button 104 of the newly changed substrate 121, the initialization of the data of the storage element 101 of the new substrate 121 is carried out. In case of exchanging the substrate 121, the certainty for carrying out initialization of data of the storage element 101 of the new substrate 121 can be enhanced. COPYRIGHT: (C)2011,JPO&INPIT
