Consumed hydrogen-off gas is discharged from a fuel cell via a hydrogen-off gas exhaust flow passage. Consumed oxygen-off gas is discharged from the fuel cell via an oxygen-off gas exhaust flow passage. The oxygen-off gas flowing through the oxygen-off gas exhaust flow passage and the hydrogen-off gas flowing through the hydrogen-off gas exhaust flow passage are mixed and diluted in a mixing portion. The gases mixed in the mixing portion flow into a combustor via a gas-liquid separator. The combustor, which includes a platinum catalyst, causes hydrogen contained in the mixed gases to react with oxygen by combustion and further reduces the concentration of hydrogen contained in the mixed gases. The mixed gases whose concentration of hydrogen has been reduced by the combustor is discharged to the atmosphere.

Onboard fuel cell system and method of discharging hydrogen-off gas

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.
