摘要： The fuel cell system includes a fuel cell, a first injection device associated with a supply of a fuel to the fuel cell, and a second injection device provided on an upstream side of the first injection device in a fuel flow passage from a fuel storage unit to the first injection device. The first and second injection devices switch a flow passage extending downstream from the fuel flow passage, between a first flow passage via the first injection device and second flow passage via the second injection device. The second injection device operates at a lower frequency than the first injection device during an operation of the fuel system.

摘要： An impedance measuring device outputs an alternating current of a prescribed frequency to each of a positive electrode terminal and a negative electrode terminal of a laminated type battery and detects an alternating-current potential difference between the positive electrode terminal and an intermediate-point terminal and an alternating-current potential difference between the negative electrode terminal and the intermediate-point terminal. The impedance measuring device adjusts an amplitude of the alternating current such that the alternating-current potential difference between the positive electrode terminal and the intermediate-point terminal and the alternating-current potential difference between the negative electrode terminal and the intermediate-point terminal coincide, and computes an impedance on the basis of the adjusted alternating current and alternating-current potential differences. Then, the impedance measuring device corrects a phase difference of the alternating currents output to the positive electrode terminal and the negative electrode terminal on the basis of a phase difference between an alternating-current potential generated at the positive electrode terminal and an alternating-current potential generated at the negative electrode terminal.
