PURPOSE: To provide fuel feed structure for a fused carbonate fuel cell, capable of simply excluding carbon in a fuel gas supply pipe without stopping the operation of a fuel cell even if carbon is deposited in the fuel gas supply pipe, by supplying fuel gas having a high hydrogen density giving priority to power generation efficiency.
CONSTITUTION: In fuel feed structure for a fuel cell having a fuel gas reformer, plural fuel gas supply pipes 6, alternatively communication-connected by a switching equipment, are arranged between the reformer 2 and a fuel cell main body 5, and also filters 7, capable of monitoring pressure loss in a supply pipe passage, are provided on the respective supply pipes 6. Branch paths, for fluid supplying/discharging in order to exclude a deposit, are provided on the passages of the supply pipes 6 on the upstream and downstream sides of the filters 7.
