An exhaust hydrogen dilution device includes a purge receiving chamber to store hydrogen purged from a fuel cell of a fuel cell system and an air passage chamber adjoining the purge receiving chamber. Diluter gas flows through the air passage chamber. An interface member between the chambers comprises an interface member having first and second vents respectively on an upstream side and a downstream side. A pressure loss at the first vent is greater than or equal to a pressure loss at the second vent. Some of the diluter gas flows into the purge receiving chamber through the first vent and is mixed with the hydrogen into a mixed gas that flows toward the second vent. The pressure losses are adjusted such that a ratio of the hydrogen flowing into the air passage chamber to a total amount of gases flowing through the air passage chamber is 4% or lower.
