Abstract
A packaging structure of a low-pressure molded fuel cell comprises a hot melt adhesive layer, which is formed through a low-pressure molding process using a hot melt adhesive that has specific material properties and will become molten when being heated. The molten hot melt adhesive is injected into the cell via injection holes formed on a housing or a mounting element to flow through a C-sectioned flow channel, so as to tightly enclose and bond to edges of the air cathode and separator for the cell. After the hot melt adhesive is solidified, a chemical-resistant hot melt adhesive layer with good sealing and enclosing ability as well as high adhesion strength and elasticity, being bubble removed at controlled pressure and the hot melt adhesive material is formed to firmly bond to the cell components and tightly seal the cell, so as to effectively prevent electrolyte in the cell from leaking.
