Device for humidifying and heating of the combustible gas being reformed for a fuel cell system, with a housing, traversed on a stipulated flow path by the combustible gas being humidified and heated, which has an inlet situated in an upper area and a more deeply positioned outlet for the combustible gas, and with a heat exchanger, which is arranged within housing and can be traversed from the bottom up in countercurrent to the combustible gas being humidified and heated by a heat transfer agent supplying the required heat, and with a device to supply water prescribed for humidified of the combustible gas. It is proposed according to the invention that the device for supplying the water prescribed for humidified include a space arranged in the lower area of housing, accommodating the water prescribed for humidified, in which the water is in thermal contact with the lower area of the heat exchanger for heating, and a steam flow path leading upward from the space for transport of water evaporated in the space to the upper area of housing, and that the stipulated flow path for the combustible gas being humidified and heated in the upper area of housing is connected to steam flow path and leads downward to outlet for the humidified and heated combustible gas separately from flow path in thermal contact with heat exchanger.
