NOVELTY - A packaging structure of a low-pressure molded fuel cell, comprises a housing (1) having several air vents, a recessed first receiving space, and at least one injection hole and at least one first gas exhaust hole; an air cathode (2) is a porous structure having several micropores, and disposed on the inner side of the wall of the housing having the air vents; a separator (3) disposed on an inner surface of the air cathode; a mounting element (4) disposed in the housing and is a hollow structure for receiving its an anode (6) and a hot melt adhesive layer.    USE - As a packaging structure useful for fuel cell (claimed) such as zinc air cell.    ADVANTAGE - The packaging structure prevents electrolyte leakage and protects the air cathode against damage, thus increases shelf life of fuel cell; and is superior to any other packaging structure.    DETAILED DESCRIPTION - A packaging structure of a low-pressure molded fuel cell, comprises a housing (1) having several air vents disposed through it wall, 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 (2) is a porous structure having several micropores, and disposed on the inner side of the wall of the housing having the air vents; a separator (3) disposed on an inner surface of the air cathode; a mounting element (4) disposed in the housing and is a hollow structure for receiving its an anode (6), where the mounting element is 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 is a C-sectioned annular structure to enclose and bond to edges of the air cathode, the separator and the mounting element; where 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. The hot melt adhesive is selected from polyamide, co-polyamide, polyester, and moisture-curing reactive polyurethane hot-melt adhesive. The inner end surface of the sealing plug and an outer end surface of the insulating ring are coated with a sealant selected from modified pitch, thermoplastic polymer, synthetic rubber and other equivalent material suitable for sealing purpose, so as to prevent oxidation of metallic upper and lower cases of the housing or any leakage of electrolyte. The anode comprises a chemical substance decomposable to produce hydrogen ions and an electrically conductive substrate coated with a catalyst. The electrically conductive substrate coated with the catalyst reacts electrochemically with hydrogen, methanol, ethanol, sodium borohydride, hydrazine or other equivalent chemical substances that are decomposable to produce hydrogen ions, so as to convert the chemical substances into hydrogen ions and generate electric energy at the same time. The catalyst is selected from platinum, gold, silver and other transition metals; and the electrically conductive substrate is selected from a porous carbon material, metal mesh, metal rod and metal sheet.
