<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing an oxygen deficiency state from occurring by detecting an oxygen concentration in a predetermined space thereof. <P>SOLUTION: The fuel cell system includes: a fuel battery having a stack with a plurality of cells connected in series, a fuel inlet for introducing liquid fuel, a fuel outlet for discharging fuel drainage, an oxidizer inlet for introducing oxidizer and an oxidizer outlet for discharging fluid containing unconsumed oxidizer and generated water; a fuel pump section for supplying the liquid fuel to the fuel inlet; an oxidizer pump section for supplying the oxidizer to the oxidizer inlet; a current detection section for detecting an output current of the fuel cell; and a control section. After electric power is generated from the fuel cell, the control section computes an oxygen consumption from a current value detected by the current detection section and a power generation time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
