Abstract: A gas-phase electrochemical module includes a separation membrane, and a cathode structure and an anode structure on both sides of the separation membrane. The cathode structure includes a cathode electrode plate, a gas diffusion layer (GDL), and a cathode catalyst layer. A portion of the GDL away from the cathode electrode plate is a hydrophilic structure. The cathode catalyst layer is formed in the hydrophilic structure, and a depth of the cathode catalyst layer penetrating into the GDL is greater than 10 ?m. The metal content of the cathode catalyst layer is greater than 95%. The cathode catalyst layer includes a first coating layer and a second coating layer on the surface of the first coating layer, and the first coating layer is a copper metal layer. The second coating layer is a single-layer or multi-layer structure, in which the material of the second coating layer includes silver, gold, indium, or an alloy thereof.

Abstract: A communication device is provided. The communication device includes a heat dissipation case, a heat conductive member, a heat dissipation base, and a communication module. The heat conductive member is thermally connected to the heat dissipation case, and the heat dissipation base is pivotally connected to the heat conductive member. The heat dissipation base is thermally connected to the heat conductive member and is adapted to be rotated between a first orientation and a second orientation relative to the heat conductive member. The communication module is affixed to the heat dissipation base.

Abstract: An antenna device and an orientation adjustment mechanism are provided. The orientation adjustment mechanism includes a holder, a rotation carrier assembled to the holder, and a torsion spring. The rotation carrier is counterclockwise rotatable from an initial position by a first predetermined angle or is clockwise rotatable from the initial position by a second predetermined angle. The torsion spring has an elastic portion disposed on the holder and two extending arms that extend from the elastic portion. When the rotation carrier is rotated from the initial position by the first predetermined angle or the second predetermined angle, the rotation carrier presses and moves one of the two extending arms, and another one of the two extending arms abuts against the limiting portion, so that the elastic portion is deformed to store an elastic force that tends to move the rotation carrier toward the initial position.

The first engaging plate is disposed adjacent to the first side plate, and the first elastic member is connected therebetween. The second engaging plate is disposed adjacent to the second side plate, and the second elastic member is connected therebetween. The first engaging plate can reciprocate between a first positioning position and a first disengagement position relative to the first side plate, and the second engaging plate can reciprocate between a second positioning position and a second disengagement position relative to the second side plate.
