摘要:
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.

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.
摘要:
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.
摘要:
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.
