Abstract: A rapid coupling device for a hydrogen storage canister. The rapid coupling device communicates the hydrogen storage canister and a fuel cell. The hydrogen storage canister includes a connecting assembly. The rapid coupling device includes a base and a communicating member. The communicating member communicates with the fuel cell, and is connected to the base. When the hydrogen storage canister is coupled to the fuel cell via the connecting assembly, the communicating member is abutted by the connecting assembly so that hydrogen in the hydrogen storage canister flows to the fuel cell through the connecting assembly and the communicating member.

Abstract: A sealing structure for sealing a proton exchange membrane fuel cell is disclosed. The fuel cell includes a membrane electrode assembly, an anode plate, and a cathode plate. Both of the plates are formed with a peripheral groove and an extended groove at a circumferential portion thereof, and silicon rubber is applied to the peripheral groove and the extended groove.

Abstract: A power management system includes a fuel cell based primary power supply and a rechargeable cell based secondary power supply and a charging control circuit arranged between the two power supplies. A controller applies a charging control signal to the charging control circuit for controlling the magnitude of a charging current for charging the second power supply. When the output voltage of the first power supply is greater than that of the second power supply, the charging control signal controls the charging current in accordance with a predetermined threshold of the output voltage of the second power supply. A switching circuit is arranged between the first power supply and the second power supply for selectively allowing the output voltage of the second power supply to be fed, together with the output voltage of the first power supply, to an external load, when the output voltage of the second power supply is greater than a predetermined level.

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.
