Abstract:
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.
Abstract:
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.

Abstract:
A hydrogen-generating device is provided, which includes a reaction tank, a first cap, a second cap and a first guiding-pipe. The reaction tank has an accommodation space for accommodating a solid reactant. The first cap covers the accommodation space, wherein the first cap has a plurality of first open-holes. The second cap is disposed on the first cap and has a second open-hole, wherein the first cap and the second cap form a chamber therebetween. The first guiding-pipe passes through the first cap and the second cap to extend to the accommodation space, wherein the first open-holes surround the first guiding-pipe. A liquid reactant is for passing through the first guiding-pipe to arrive in the accommodation space and reacts with the solid reactant to generate a hydrogen. The hydrogen passes through the first open-holes to arrive at the chamber and then is expelled from the second open-hole.
Abstract:
A base station, a femtocell, and a handover monitoring method thereof are provided. A wireless network system comprises a server, a mobile device, the base station, and the femtocell. The base station transmits a monitoring signal to the femtocell after it obtains a piece of information corresponding to the mobile device from the server. The femtocell keeps detecting whether a signal is transmitted by the mobile device after it receives the monitoring signal. The femtocell transmits a response signal corresponding to the monitoring signal to the base station after it detects the signal transmitted by the mobile device. The base station transmits a handover signal to the mobile device after it receives the response signal so that the mobile device handovers from the base station to the femtocell. A handover monitoring from the base station to the femtocell for the mobile device is provided by the hand monitoring method.
