Patent ID: 8551672

Claim:
A packaging structure of a low-pressure molded fuel cell, comprising: a housing having a plurality of air vents disposed through at least one wall thereof, a recessed first receiving space formed on and around an inner side of the wall having the air vents, and at least one injection hole and at least one first gas exhaust hole disposed through a peripheral wall of the housing to communicate with the first receiving space; an air cathode being a porous structure having a plurality of micropores, and disposed on the inner side of the wall of the housing having the air vents; a separator disposed on an inner surface of the air cathode; a mounting element disposed in the housing and being a hollow structure for receiving an anode therein; the mounting element being provided with a raised annular flange on one side adjacent to the separator, such that a recessed second receiving space is formed around an outer periphery of the raised annular flange; and the second receiving space together with the first receiving space forming a C-sectioned flow channel; and a hot melt adhesive layer being a C-sectioned annular structure to enclose and bond to edges of the air cathode, the separator and the mounting element; wherein the hot melt adhesive layer is formed through a low-pressure molding process, in which a hot melt adhesive in a molten state is injected into the C-sectioned flow channel via the injection hole provided on the housing; the molten hot melt adhesive flows through the C-sectioned flow channel to bond to and enclose the edges of the air cathode and the separator while any air in the C-sectioned flow channel is discharged via the first gas exhaust hole; and, the hot melt adhesive layer is formed when the hot melt adhesive is solidified; wherein the mounting element is provided with a through hole on a sidewall, and the housing is provided with an insertion hole at a position corresponding to the through hole; the anode is loaded in the mounting element via the insertion hole and the through hole; an anode current collector is inserted into the mounting element through the insertion hole and the through hole, such that an inner end of the anode current collector is in contact with the anode; and a sealing plug is used to seal the through hole and an insulating ring being fitted in the insertion hole for firmly holding an outer end of the anode current collector that is extended through the housing for producing electric current; wherein, after the anode current collector has been inserted through the through hole, a closed space is formed between the insulating ring and the sealing plug; and an amount of hot melt adhesive is injected into the closed space via a recess communicably provided to one side of the through hole.
