ABSTRACT:
A noise eliminator for a fuel cell, where an outer shell has a reception section in which a sound absorption material is placed between the outer shell and an inner pipe and has a water discharge section that is positioned so as to face a lower portion in the vertical direction of the inner pipe and in which the sound absorption material is not placed between the outer shell and the inner pipe. The water discharge section receives water flowing into the outer shell and allows the water to flow to the outside of the outer shell. Although the water discharge section receives water flowing into the outer shell, the sound absorption material inside the noise eliminator does not absorb the water from the water discharge section and does not contain it because there is no sound absorption material in the water discharge section.
