Abstract:
PROBLEM TO BE SOLVED: To provide a muffler capable of reliably diluting unreacted hydrogen gas discharged from a fuel cell, while suppressing noise generated by the dilution.SOLUTION: A muffler 6 comprises: a muffler body 61 which is formed in a cylindrical shape and has a flow path 61a formed therein; and a wing-shaped plate 62 which is formed in a tabular shape and is arranged in a wing-shaped plate arrangement part 611 of the muffler body 61. The wing-shaped plate 62 has: a first wing-shaped part 621 extending along an axis line C of the wing-shaped plate arrangement part 611; and a second wing-shaped part 622 extending from the downstream end of the first wing-shaped part 621 toward the downstream side. When viewing the wing-shaped plate 62 along a Z-direction perpendicular to the axis line C and a thickness t direction of the first wing-shaped part, an inclination angle θ of the second wing-shaped part 622 with respect to the extension direction of the first wing-shaped part 621 ranges from 16 to 45 degrees.SELECTED DRAWING: Figure 3
