<P>PROBLEM TO BE SOLVED: To provide an electric power measuring device in which by calculating flow rate data corresponding to input energy supplied into a fuel cell and electric power data corresponding to output energy by means of the electric power measuring device, synchronizing of respective data can be taken, and the measurement accuracy is improved, and the efficient measurement can be carried out simply without installation of another computing device. <P>SOLUTION: In this device, the efficiency of the fuel cell is measured based on the input energy to the fuel cell, which is calculated from the difference between the flow rate of hydrogen fuel supplied to the fuel cell in which electric power is generated by the reaction of hydrogen fuel and oxygen and the flow rate of the hydrogen fuel discharged from the fuel cell, and based on the output energy of the fuel cell calculated by measuring the electric power supplied from the fuel cell. <P>COPYRIGHT: (C)2004,JPO |
