1. A fuel reforming apparatus comprising:
a pre-reformer configured to convert a fuel gas to methane by bringing the fuel gas into a reaction with water;
a reformer configured to generate a mixture gas including hydrogen by bringing the fuel gas pre-reformed by the pre-reformer into a reaction with the water;
a reformer burner configured to supply heat to the reformer; and
an exhaust gas supply line configured to cause an exhaust gas discharged from the reformer burner to be supplied to the pre-reformer as a heat source for the reaction of the pre-reformer;
a first discharge line configured to discharge an exhaust gas generated by the pre-reformer; and
a second discharge line branched from the exhaust gas supply line and connected to the first discharge line such that the exhaust gas generated by the reformer burner is exhausted.
