Document Type and Number:
Japanese Patent JP5760948
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress deterioration in measuring accuracy of current caused by induction voltage and influence of magnetic field, in a current measurement device measuring the current flowing in a fuel cell.SOLUTION: A current measurement device 100 comprises: a current measurement part 101 including a first electrode 111, a second electrode 151, and a resistor 131; and a voltage sensor 102 for detecting electric potential difference, the sensor 102 detecting the electric potential difference between two points in the resistor 131. The resistor 131 is connected to the first electrode 111 via a first conduction via hole 101a, and connected to the second electrode 151 via a second conduction via hole 101b. The voltage sensor 102 for detecting electric potential difference is connected the resistor 131 via a pair of detection via holes 101d and 101e. In the current measurement device having such a configuration, a pair of detection via holes 101d and 101e are provided for the first conduction via hole 101a and the second conduction via hole 101b respectively.
