Abstract: This invention is related to a metal hydride storage canister, comprising a storage canister body, a wafer baffle stacked on the body for containing metal hydride of a pre-determined amount, and a tubing having a porous surface for securing the wafer baffle in the body and for guiding hydrogen discharged from the metal hydride to an outlet of the body. This invention further discloses the manufacture of the storage canister.

Abstract: A device for regulating temperature and humidity of a reaction gas to be supplied to a fuel cell stack includes a temperature regulation section provided with a first gas guide board through which the reaction gas flows, a coolant guide board through which a coolant from the fuel cell stack flows and a first partition interposed between the first gas guide board and the coolant guide board for exchange of heat between the reaction gas and the coolant and a humidity regulation section coupled to the temperature regulation section with a second partition therebetween and comprised of a second gas guide board through which the temperature-regulated gas flows and a fluid guide board through which a fluid from the fuel cell stack and rich of water contents flows and a humidity exchange film interposed between the second gas guide board and fluid guide board to allow for exchange of water contents between the temperature-regulated gas and the fluid.

Abstract: A flow field pattern for separator plates of a fuel cell system is disclosed. The separator plate is formed with a gas inlet port at a first edge, a gas outlet port at a second edge, and a plurality of gas channels at a first surface. A first guide channel is arranged at the first edge adjacent to the gas inlet port and a second guide channel is arranged at the second edge adjacent to the gas outlet port. Each of the guide channels comprises a guide section and an outlet section. A part of the guide section of the first guide channel is located opposite to the outlet section of the second guide channel. The two ends of the gas channels in a guiding zone of the separator plate are respectively connected with the gas inlet port at the first edge and the guide section of the second guide channel at the second edge.

Abstract: An air cooling system for cooling an air-cooled fuel cell system including a plurality of cooling air channels formed in the fuel cell system is disclosed. The fuel cell system is provided with a fan casing at a cooling air inlet side of the cooling air channels. At least one fan is mounted to an opening of the fan casing. When the fan is turned on, it generates a cooling air flow which flows in from the cooling air inlets, through the cooling air channels and flows out from the cooling air outlets. A temperature sensor is arranged at a position between an anode plate of a single cell unit and a cathode plate of an adjacent single cell unit for detecting a temperature of the fuel cell system. A filter casing is provided to fuel cell system at the cooling air inlet side, and a filter is mounted to an opening of the filter casing for filtering dust and impurities. A cooling air guiding cover is provided at an external side of the fan casing for guiding the cooling air to a humidifier.
