A fuel cell humidifier for performing humidification via a water exchange film by bringing together supplied gas to be supplied to a fuel cell, and off-gas discharged from the fuel cell. The fuel cell humidifier includes: a humidification cell having a supplied gas passage for allowing the supplied gas to flow through, an off-gas passage for allowing the off-gas to flow through, and the water exchange film; and a gas flow cell for allowing either the fuel gas or the off-gas to flow through. The invention provides a fuel cell humidifier, and a fuel cell system equipped with the fuel cell humidifier, that can appropriately adjust the humidification value and the heat exchange amount, prevent humidification characteristics from being influenced by ambient temperature changes, and exhibit enhanced reliability, stability and control. |
