Abstract: The invention discloses an integral multi-stack system of fuel cell. The system includes at least one pair of fuel cell stacks, a manifolding functional frame, and an attaching device for securely installing each pair of fuel cell stacks to the manifolding functional frame. Each fuel cell stack has a pair of end plates and six openings including a fuel inlet, an oxidant inlet, a cooling agent inlet, a fuel outlet, an oxidant outlet, and cooling agent outlet all formed on one end plate thereof. When the fuel cell stacks are securely installed onto the manifolding functional frame, each opening thereof is air commnicateable to a sub-passage defined in the body without being communicated with one another and respectively communicated to a plurality of main passages defined in the body, making the main passages and the sub-passages be able to be used to supply and/or discharge gas or liquid being used by all the fuel cell stacks integrated.

Abstract: The invention relates to a movable packing box having a hexahedron comprised of six movable boards such as four vertical boards, a bottom board and a top board. Wherein a door is installed on one of the vertical boards and the structure between the bottom and vertical boards is a pivotal connection. The movable packing box is easy to be moved, disassembled and folded up for packing. Therefore space and transportation expenses can be saved greatly and it is convenient for transportation.

Abstract: An air humidifying system includes an air humidifying device including a humidifying unit, having a dry air inlet and a humidified air outlet, for humidifying a flow of dry air from the dry air inlet to a humidified air exiting at the humidified air outlet. An air filtering unit has an air filtering inlet for guiding an ambient air as the dry air and an air filtering outlet communicating with the dry air inlet of the humidifying unit for purifying the dry air before entering into the humidifying unit. An air supplying unit has an air inlet port communicating with the humidified air outlet of the humidifying unit and an air outlet port adapted for communicating with an air inlet of the fuel cell stack, wherein the air supplying unit is adapted for guiding the humidified air into the fuel cell stack in a pressurized manner.

Abstract: A mounting frame includes a cell enclosure and a retention arrangement. The cell enclosure comprises a first boundary frame including four first boundary legs and a second boundary frame including four second boundary legs extending to align with the four first boundary legs respectively to form a box-shaped structure for fittingly framing a fuel cell stack. The retention arrangement includes four pairs of first and second coupling members provided at free ends of the four first boundary legs and the four boundary legs respectively, and four affixing elements arranged when the four first boundary legs are aligned with the second boundary legs to overlap the first and second coupling members, the affixing element is detachably connected the first and second coupling members so as to securely lock up the first boundary frame with the second boundary frame for retaining the fuel cell stack therewithin.
