摘要： A fuel cell system includes a first fuel cell, second fuel cell, first voltage detector, second voltage detector, and controller. The first voltage detector detects voltage of first unit cells of the first fuel cell for every “N” unit cells on average, and the second voltage detector detects voltage of the second fuel cell as a whole, or detects voltage of second unit cells of the second fuel cell for every “M” unit cells on average, where “M” is larger than “N”. The controller determines whether any of the second unit cells is in a fuel deficiency state, based on the detection result of the first voltage detector, when a predetermined condition under which states of the first fuel cell and the second fuel cell are regarded as being close to each other is satisfied.

摘要： A fuel cell stack includes a stack body of power generation cells stacked in a horizontal direction. An oxygen-containing gas flow field is formed in the fuel cell stack, for allowing an oxygen-containing gas to flow along an electrode surface of a membrane electrode assembly. A plurality of oxygen-containing gas discharge passages for discharging the oxygen-containing gas as a reactant gas pass through the fuel cell stack in a stacking direction of the power generation cells. Each of the oxygen-containing gas discharge passages is connected to an outlet. The plurality of oxygen-containing gas discharge passages are connected together by a first connection channel at an end opposite to the outlet.
