A hydrogen generating device is adapted for a fuel cell. The hydrogen generating device includes a casing, a button, a solid reactant, a bag-shaped body, and at least one flexible element. The casing has a containing space and an opening. The button is integrally formed and connected to the casing to seal the opening. The solid reactant is disposed in the casing. The bag-shaped body is disposed in the casing and contains a liquid reactant. The flexible element is connected to the casing and is located in the containing space. The flexible element includes a bending end, wherein the flexible element is aligned to the button and is located between the button and the bag-shaped body. When the button is pressed, the button pushes the flexible element so the bending end pierces the bag-shaped body, and the liquid reactant flows out and reacts with the solid reactant to generate hydrogen.

A lamp source module includes a holder having an air inlet and an air outlet, a gas discharge lamp having a lamp reflector assembled onto the holder and a burner disposed in the lamp reflector, a light cover assembled on the holder and surrounding the lamp reflector, a blower duct communicating with the air inlet and extending along the exterior of the lamp reflector to the bottom of the lamp reflector, and an airflow generator communicating with the blower duct and capable of providing a cooling airflow. The air inlet is capable of causing the cooling airflow to enter the blower duct. The blower duct is capable of directing the cooling airflow to the bottom of the lamp reflector to make the cooling airflow pass through a sandwiched space surrounded by the lamp reflector and the light cover and then discharge from the air outlet.

A method for controlling a fuel cell system is provided, which includes following steps. It is determined whether a hydrogen flow in a fuel cell stack in the fuel cell system is sufficient, and when the hydrogen flow is determined to be sufficient, an output voltage of the fuel cell stack is gradually deceased, and an output current of the fuel cell stack is continually detected until the output current of the fuel cell stack stops increasing. When the hydrogen flow is determined to be insufficient, the output voltage of the fuel cell stack is gradually increased, and the output current of the fuel cell stack is continually detected until the output current of the fuel cell stack starts to decrease.

An apparatus for generating hydrogen including a housing, a reservoir, and a piston is provided. The housing has a top wall, a bottom wall, and a sidewall. The top wall has vents and a protrudent column extending to the interior of the housing. At least one vent communicates with the top wall and the protrudent column and rest of the vents surround the protrudent column. The reservoir is disposed in the housing for storing a solid state reactant and divides the housing into a first chamber and a second chamber. The first chamber is located between the top wall and the reservoir. The second chamber is located between the bottom wall and the reservoir for storing a liquid reactant. The piston is disposed on the bottom wall. The piston is used to push the liquid reactant towards the reservoir to react with the solid state reactant to generate hydrogen.
