Abstract
A fuel cell system (100) is provided with a voltage detection device (41) that detects a cell voltage of a cell group containing one or more cells (11), a current density detection device (42) that detects a generated current density of the cell group, and a determination portion (52) that determines the presence or absence of an inflection point of a change in the cell voltage relative to the generated current density based on the detection results of the voltage detection device and the current density detection device.

17. A method for detecting the status of a fuel cell, comprising:
-
a voltage detection step of detecting a cell voltage of a cell group containing one or more cells; a current density detection step of detecting a generated current density of the cell group; and a determination step of determining the presence or absence of an inflection point of a change in the cell voltage relative to the generated current density based on the detection results in the voltage detection step and the current density detection step. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
