The fuel cell system is simplified and made more compact while providing the favorable recirculation of hydrogen-containing off-gas regardless of the increase or decrease in its flow rate. The fuel cell system is provided with: a cell unit that generates electricity by means of separating hydrogen-containing gas and oxygen-containing gas from each other while placing in flow contact to each other; and a recirculation mechanism for recirculating to the cell unit hydrogen-containing off-gas discharged from the cell unit. The fuel cell system has a flow rate determination unit that determines whether or not the hydrogen-containing gas fed to the cell unit is less than a predetermined flow rate; and a gas feeding pressure varying mechanism that cause the pressure of the hydrogen-containing gas to vary to increase and decrease when it is determined that the hydrogen-containing gas fed to the cell unit is less than the predetermined flow quantity.
A fuel cell system including a cell unit generating power by separating hydrogen-containing gas and oxygen-containing gas in flow contact with each other, and a recirculation mechanism to recirculate hydrogen-containing off-gas discharged from the cell unit back to the cell unit, comprising:
A fuel cell system including a cell unit to generate power by separating hydrogen-containing gas and oxygen-containing gas from each other while bringing in flow contact with each other, and a recirculation mechanism to recirculate hydrogen-containing off-gas to the cell unit by way of involution action of the hydrogen-containing gas fed to the cell unit, comprising:
