PROBLEM TO BE SOLVED: To prevent the lowering of performance of the reforming catalyst due to the condensation of fuel, such as methanol and steam. SOLUTION: This method of stopping a reforming equipment for fuel cell is provided with an alloy container 12 for storing the hydrogen storage alloy 11 inside thereof, a reforming gas line 14 for leading the reformed gas from a reformer into the alloy container, and a hydrogen gas line 16 for communication the alloy container with an upstream side of the reformer. (a) A part of the reformed gas is introduced to the hydrogen storage alloy via a reformed gas line during the operating of the reformer. (b) Hydrogen is discharged from the hydrogen storage alloy during the stop of the operation of the former, and the hydrogen is supplied to the upstream side of the reformer via the hydrogen gas line so as to purge the fuel and the moisture left in the reformer. (c) The reformer has hydrogen sealed in. |
