摘要:
A hydrogen generation system comprising solid hydrogen fuel, a liquid absorbent material, and a phase-change material is provided. When the liquid (usually water, alcohol, or aqueous solution of alcohol, aqueous solution of salt or aqueous solution of acid) in the absorbent material contacts with the solid hydrogen fuel, the solid hydrogen fuel will react with the liquid to release hydrogen and generate heat. The heat as generated will accumulate to increase the reaction temperature, and then boost the hydrogen-releasing rate. The phase-change material is adjacent to the solid hydrogen fuel for absorbing and storing the reaction heat, so as to stabilize the reaction temperature. Therefore, the hydrogen-releasing rate is kept as constant to achieve a steady hydrogen flow.

A method for fabricating a bi-polar plate of a fuel cell and the bi-polar plate thereof are presented. A graphite film is formed first. Next, a polymeric material added with electrically conductive powder is coated on a surface of a metal substrate. The graphite film is disposed on the polymeric material and the polymeric material is hardened to form an adhesive layer, such that the graphite film is attached on the surface of the metal substrate.

A power supply device is provided. The power supply device includes a fuel cell, a hydrogen generator, a check valve and an exhaust valve. The fuel cell has a hydrogen inlet and a hydrogen outlet. The hydrogen generator is connected to the hydrogen inlet and used for generating hydrogen. The check valve is disposed in the hydrogen inlet and used for preventing the hydrogen within the fuel cell from flowing to the hydrogen generator, and preventing exterior air from entering the fuel cell. The exhaust valve is disposed in the hydrogen outlet for exhausting the hydrogen within the fuel cell.

A hydrogen-generating equipment including a hydrogen-generating device and a hydrogen-purifying device is provided. The hydrogen-generating device is capable of generating a hydrogen-gas, a water-vapor mixed in the hydrogen-gas and a toxic-gas mixed in the hydrogen-gas. The hydrogen-purifying device includes a water-vapor filter unit and a toxic-gas filter unit. The hydrogen-gas passes through the water-vapor filter unit to remove the water-vapor mixed in the hydrogen-gas. The toxic-gas filter unit includes a filtering assembly. The surface of the filtering assembly has a plurality of hydroxyls. After the hydrogen-gas passes through the water-vapor filter unit, the hydrogen-gas passes through the toxic-gas filter unit, and the toxic-gas mixed in the hydrogen-gas reacts with a plurality of hydroxyls on a surface of the filtering assembly to remove the toxic-gas.

A fan filter unit includes a housing having a side wall and a top wall with a bell mouth serving as an air inlet and an open bottom to which a filtering net is attached to serve as an air outlet. A centrifugal fan is arranged in the housing to drive the air from inlet. The fan assembly has an output port for driving an air flow toward the air outlet. A guide plate is arranged in the housing for guiding the air flow along the path from the fan assembly to the air outlet. A sound-absorbing structure including a plurality of wedge-shaped elements made of a sound-absorbing material is attached to the side wall. The wedge-shaped elements are arranged in a line for effectively reducing noise level caused by the operation of the fan assembly. A second line of wedge-shaped elements is optionally attached to the side wall with the wedge-shaped elements of the two lines alternating each other.

摘要:
An one-off and adjustment method of hydrogen releasing from chemical hydride. The “one/off” of hydrogen release is controlled by the “contact/non-contact” procedures between the reactants. First, at least a hydride powder, a catalyst powder and a water-containing reactant are provided, and at least any two of three are mixed to form a mixture. Hydrogen gas is generated by adjusting a contact area between the mixture and the remaining one. The hydrogen-releasing reaction is terminated when a non-contacting state between the mixture and the remaining one occurs. Alternatively, an inhibitor or an inhibiting method could be used for suppressing or terminating the hydrogen-releasing reaction. The hydrogen-releasing rate could be controlled and adjusted by the extent of suppression.

A design of bipolar plate gas moisturizing apparatus of the fuel cell is disclosed. Using a channel installed in the middle section of fuel channel and a water-absorptive material attached to its bottom, water is directly guided into the fuel channel of the bipolar plate in the fuel cell. The fuel inside the fuel channel thus obtains sufficient water to enhance the humidity of the proton exchange membrane and the efficiency of the fuel cell.
