A fuel cell fuel reformer including a gas reactor for producing reformed fuel and an electric heater for heating the gas reactor. An external container includes an inner vacuum chamber, which accommodates the gas reactor and the electric heater, and receiving portions. An electric wire extends through the external container to supply electric power to the electric heater in the inner vacuum chamber. Fluid tubes are received by the receiving portions and extend through the external container. A sealant seals gaps between the fluid tubes and the receiving portions. The gas reactor, the fluid tubes, the external container, and the sealant each have thermal expansion coefficients, with the maximum one of the thermal expansion coefficients being ten-times the minimum one of the thermal expansion coefficients or less.
