A method for humidifying a supply of fuel and air for use in a fuel processor includes in one embodiment receiving the supply of the fuel and air at a first temperature such as ambient temperature, heating the supply of fuel and air to a second temperature greater than the first temperature, and combining the supply of fuel and air at the second temperature with a supply of water. One embodiment of a fuel cell system incorporating such method includes a humidifier for humidifying supply of dry fuel and air, a fuel processor for reforming the supply of humidified fuel and air and producing a supply of reformate, a fuel cell for receiving the reformate and generating electricity. A heat exchanger is provided for heating the supply 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.
