A honeycomb body is produced with a number of sheet layers, of which at least a part are at least partly structured sheet layers, which lend the honeycomb the property of permitting fluid to flow through the same as a result of the structure thereof. The wedge has at least one central opening between said two grooves and said central opening passes completely through said wedge along an axis Ac substantially parallel to the axes Ag1 and Ag2 of said grooves, which renders said wedge elastically deformable. Electrodes of the semiconductor chip are respectively electrically connected to connecting terminals exposed through openings of the second solder resist section via bonding wires. The controller receives a signal from the current sensor and controls the operation of the half active bridge rectifier to produce a light emitting diode current based on the current sensed by the current sensor. The Sn plating layer has an average crystal grain size of about 1 m or less. The first path channels the first portion of the reformed fuel stream to an anode inlet.
