摘要： A fuel cell stack includes a number of modularized plate structures including an anode plate, a cathode plate, water coolant plates and air coolant plates. The anode and cathode plates are designed to form hydrogen and air channels that allow for uniform distribution and even flow of hydrogen and air through the channels with the channels of each particular plate having substantially identical length in order to enhance electrochemical reaction between hydrogen and oxygen contained in the air with respective catalysts in the fuel cell stack. Also a sufficient amount of air is allowed to flow through the cathode plate to enhance output power of the fuel cell stack. The coolant plates adapt a split design, which introduces turbulence in the coolant channels to enhance heat removal.

摘要： A control device for controlling the operation of a fuel cell system is disclosed, including a microprocessor, a voltage detection circuit, a current detection circuit, a hydrogen pressure detection circuit, a temperature detection circuit, an air flow rate control circuit that is controlled in a pulse width modulation manner, and a pulse signal generation circuit. The air flow rate control circuit is controlled by the microprocessor for regulating the air flow rate through an air supply conduit in a pulse width modulation manner in accordance with output current of a fuel cell stack. The pulse signal generation circuit is controlled by the microprocessor to generate pulse signals for controlling hydrogen flow through a hydrogen supply conduit. The control device monitors the operation conditions of the fuel cell system and performs a preset control process to control the operation of the fuel cell stack so as to optimize the efficiency and overall performance of the fuel cell system.

摘要： An electric scooter includes a scooter frame having a rear cover inside which a fuel cell stack is mounted in an inclined manner and a center cover connected to the rear cover by a footstep section. A front cover is mounted to a front side of the scooter frame and forms an interior space with the center cover. A hydrogen canister holder is mounted in the interior space for retaining a number of hydrogen storage canisters in an inclined manner for supply of hydrogen to the fuel cell stack. The canisters are arranged in pair on opposite sides of a centerline of the scooter frame. A heat dissipation system including a coolant container, a heat exchanger, and a pump is further provided in the interior space to maintain the hydrogen storage canisters at a proper operation temperature.
