Abstract:
1. A fuel cell system, comprising: at least one fluid drive device disposed in a fluid passage connected to a fuel cell main body that forcibly circulates fluid; an operation state judgment unit that judges whether or not the fuel cell main body is operating for power generation; a temperature detecting unit that detects a temperature of the fuel cell main body; an impedance detecting unit that detects the impedances of fuel battery cells in the fuel cell main body; and a forcible drive unit that counts a trip number, wherein a trip is defined as a time period between starting and stopping operation of the fuel cell main body for power generation, and wherein the forcible drive unit is programmed to forcibly drive the at least one fluid drive device regardless of whether the at least one fluid drive device is to be operated during an operation of the fuel cell main body if at least the following conditions are all true: (a) the counted number of trips is equal to or greater than a predetermined number of trips, which is equal to or greater than one; and (b) the fuel cell main body is operating for power generation; and (c) the temperature of the fuel cell main body does not exceed a predetermined temperature range; and (d) the impedances of the fuel battery cells do not exceed a predetermined impedance range.
