A method for humidifying a mixture of dry fuel and air for use in a fuel processor may include receiving a mixture of dry fuel and air at a first temperature such as ambient temperature, heating the mixture of dry fuel and air to a second temperature greater than the first temperature, and combining the mixture of dry fuel and air at the second temperature with water. A fuel cell system incorporating such method may include a humidifier for humidifying a mixture of dry dry fuel and air which is processed in a fuel processor to produce reformate, and a fuel cell for receiving the reformate and generating electricity. A heat exchanger is provided for heating the mixture of dry fuel and air prior to humidification in the humidifier. The heat exchanger may be provided in the fuel processor or operably connected to an anode tail-gas oxidizer.
