Abstract: A fuel reformer for producing a steam reforming reaction between fuel and water on a reforming catalyst includes a fuel injection part that injects and supplies fuel into the reforming catalyst, a temperature measurement part that measures a temperature of the reforming catalyst, and a determination part that determines whether a process for recovering the reforming catalyst is necessary. The determination by the determination part is made based on a temperature change of the reforming catalyst when the steam reforming reaction is produced.

Abstract: At least one of nozzle holes is provided as a non-circular nozzle hole where the ratio of the longest diameter to the shortest diameter of an outlet opening portion is greater than 1. A virtual non-circular cone and a virtual circular cone are defined for each of the non-circular nozzle hole and a circular nozzle hole where the ratio of the longest diameter to the shortest diameter of the outlet opening portion is 1. At least two adjacent nozzle holes are formed such that the virtual non-circular cone does not interfere with the virtual circular cone or the virtual non-circular cone.

Abstract: A fuel reformer for producing a steam reforming reaction between fuel and water on a reforming catalyst includes a fuel injection part that injects and supplies fuel into the reforming catalyst, and an injection control part that controls an injection amount of fuel by the fuel injection part. The injection control part controls the injection amount in order that a temperature of the reforming catalyst is not lower than a preset given temperature. The fuel reformer further includes a temperature obtaining part that measures or estimates the temperature of the reforming catalyst, and a target value calculation part that calculates a target value of the injection amount, such that the temperature of the reforming catalyst after fuel is injected by the fuel injection part is equal to or higher than the given temperature. The fuel injection part is controlled such that the injection amount coincides with the target value.
