Abstract: Disclosed are a fuel cell system capable of maintaining hydrogen density of the exhaust gas discharged from the fuel cell system at a level below the tolerance limit so that any fears about fire and/or explosion can be dispelled and the safety of the system can be remarkably improved, and a humidifier therefor. The fuel cell system of the present invention comprises a fuel cell stack; and a humidifier configured to (i) humidify an air supplied from outside by means of an off-gas discharged from the fuel cell stack and (ii) supply the humidified air to the fuel cell stack, wherein the off-gas is mixed with at least a portion of the humidified air in the humidifier.

Abstract: The present invention relates to a membrane humidifier for a fuel cell capable of simplifying a fuel cell system and miniaturizing the fuel cell system by performing humidification by moisture exchange and cooling by heat exchange in one membrane humidifier, and a fuel cell system comprising same. The membrane humidifier for a fuel cell of the present invention comprises both a humidification module and a heat exchange module in a housing part, and distributes a first fluid to the humidification module and the heat exchange module at a variable distribution ratio.

Abstract: The present invention relates to a composite hollow fiber membrane, a manufacturing method therefor, a hollow fiber membrane cartridge including same, and a fuel cell membrane humidifier, the composite hollow fiber membrane comprising a hollow fiber membrane and a contaminant collection layer coated on the inner surface of the hollow fiber membrane. The composite hollow fiber membrane can prevent performance deterioration of a fuel cell by removing, without a separate gas filtering device, contaminants such as nitrogen oxide (NOx), sulfur oxide (SOx), and ammonia (NH3) during a humidifying process.
