An apparatus and method for humidifying a fuel cell flows moisture-containing fuel cell exhaust against a first side of a humidification membrane. A second side of the humidification membrane is in physical contact with the inlet air flow. Moisture from the exhaust air is transferred across the humidification membrane to the inlet air flow. The humidified inlet air flow conveys moisture to the power section of the fuel cell. In this manner, fuel cell components requiring humidification, for example a proton exchange membrane, are prevented from becoming dehydrated and inoperable.
