Abstract: Provided is a package structure for a fuel cell, including a first polar plate and a second polar plate. The first polar plate includes a first recess used to accommodate an anode of a membrane electrode assembly (MEA), and at least a first sealed flange surrounding the first recess. The second polar plate includes a second recess corresponding in position to the first recess and used to accommodate a cathode of the MEA, and at least a first sealed groove surrounding the second recess and corresponding in position to the first sealed flange. The first sealed flange and the first sealed groove are employed to hold by clamping the periphery of the proton exchange membrane of the MEA, so as to accomplish sealing.

Abstract: A hot press mold for a MEA of fuel cell is provided. The hot press mold includes: a first mold including a first alignment part; a second mold including a second alignment part, being piled up a first electrode, a film, and a second electrode on it, whereby the first and second alignment parts join together to pile the first electrode, the film, and the second electrode between the first and second mold; and a lock loop secures the edge of the first and second mold to fix the first and second mold.

Abstract: A column type fuel cell is provided, including a column electrode, a first catalytic layer, one or more channels, an electrolyte layer, a second catalytic layer, and a ring electrode. The surrounding surface of the column electrode has several protruding blocks. The first catalytic layer is on the surrounding surface of the column electrode to form a pillar, and is connected to the protruding blocks to form the channel passing through two ends of the pillar. The first catalytic layer is covered with the electrolyte layer, the electrolyte layer is covered with the second catalytic layer, and the second catalytic layer is covered with the ring electrode.

Abstract: The present invention discloses a burr removing apparatus including a base for placing the compact disc on, and a pressing apparatus equipped on the base and corresponding to the inner circle of the compact disc for moving up and down to eliminate a bur at the inner circle of the compact disc. An upper and a lower inhaling apparatus are respectively equipped in the pressing apparatus and the base, and extend respectively to the surfaces of the pressing apparatus and the base. The upper and lower inhaling apparatus have the upper and lower inhaling holes to inhale the bur eliminated. The present invention eliminates and inhales the redundancy before bonding the discs, so the smoothness of the disc can be improved to avoid the bubbles while bonding, and providing a disc with good mechanical properties and weather-resistance.
