PROBLEM TO BE SOLVED: To shorten a warm-up time of a hydrogen feeder for a fuel cell and provide a hydrogen feeder for a fuel cell capable of recovering excessive heat generated during operation or directly after stoppage of a fuel reformer and recycling it for a next time as warming up energy of the fuel reformer. SOLUTION: The hydrogen feeder for the fuel cell is provided with the fuel reformer 1 producing hydrogen by reforming fuel, the fuel cell generating power by the hydrogen discharged from the fuel reformer 1, a first hydrogen storage material releasing heat by storing hydrogen and absorbing heat by releasing hydrogen, and a second hydrogen storage material capable of releasing hydrogen at a temperature lower than the first hydrogen storage material. It is characterized by that the first hydrogen storage material is provided so it can exchange heat with the fuel reformer 1, and hydrogen released from the second hydrogen storage material is stored in the first hydrogen storage material during warming up of the fuel reformer. |
