摘要： A fuel cell system capable of improving the chemical durability of a membrane electrode assembly by compensating for the amount of an antioxidant lost within the electrolyte membrane or electrode of the fuel cell stack in such a manner that the antioxidant is provided from an antioxidant supply device, provided in a fuel processing system and/or an air processing system, to a fuel cell stack, in preparation for a case where the antioxidant within the electrolyte membrane or electrode is lost due to the dissolution or migration characteristic of the antioxidant.

摘要： A humidifier for a fuel cell includes: a bundle of hollow fiber membranes disposed therein, such that an intake gas flows inside the bundle of hollow fiber membranes; a housing configured to accommodate the bundle of hollow fiber membranes, such that an exhaust gas, which has a higher humidity than the intake gas, flows inside the housing; and a guide member disposed in the housing to restrict a movement of the bundle of hollow fiber membranes inside the housing. Coolant flows through the guide member to cool the exhaust gas to promote condensation of the exhaust gas.

摘要： Disclosed is a device for adjusting humidification gas of a membrane humidification device of a fuel cell. In particular, the device is adapted to induce changes in differential pressure and velocity of the wet air for each division module and to improve the humidification efficiency by sequentially mounting the division modules divided into various numbers to the interior of a housing of the membrane humidification device, thereby adjusting the density of the hollow fiber membrane filled in each division module.

摘要： A humidifier for a fuel cell is provided and includes a housing having, at a first side, a moist air supply port through which moist air is supplied from a fuel cell stack and having, at a second side, a moist air discharge port. A humidifying membrane is disposed in the housing and allows dry air to flow along the inside of the humidifying membrane. A bypass flow path is formed in the housing to allow a part of the moist air supplied to the moist air supply port to continuously flow to the moist air discharge port without passing through the humidifying membrane, thereby adjusting the amount of humidification and a differential pressure of the humidifier based on an operating condition of a fuel cell.

摘要： Disclosed is a humidifier for a fuel cell system including a separator plate which is corrugated to provide an alternating concave-convex surface, and humidifying films provided at an upper end and a lower end of the separator plate, respectively. More specifically, the separator plate and the humidifying films form a series of drift spaces in which a width of an upper end portion is different from a width of a lower end portion which is contact with the humidifying film.

摘要： A humidifier for a fuel cell includes a body, first and second humidifying spaces formed inside the body, an exhaust gas inlet and an exhaust gas outlet for supplying exhaust gas released from the fuel cell stack into the first and second humidifying spaces, a passing space formed inside the body and directly or indirectly communicated with the second humidifying space and the fuel cell stack. The inflow gas flows into the passing space from the first humidifying space. A valve is installed in the passing space to allow the inflow gas introduced into the passing space to flow into the fuel cell stack with or without passing through or to allow some of the inflow gas introduced into the passing space to flow into the fuel cell stack passing through the second humidifying space and others of the inflow gas introduced into the fuel cell stack without passing through the second humidifying space.
