PURPOSE:To ensure melt-bonding with an insert and to prevent electrolyte leakage from the interface by injecting molten plastic from a gate arranged in a part corresponding to the back side of an electrode accommodated in the molding space of a mold for insert injection molding. CONSTITUTION:A gate 33 positioned in a part corresponding to a thick part 31a of an insulating frame 31 is replaced with a gate 37 positioned in a part corresponding to the back side of an electrode 30. When molten plastic is injected from the gate 37, high temperature molten plastic is directly brought into contact with the electrode 30 before it is cooled in a molding space 36, and strongly bonded to the electrode 30 to form an insulating frame 31 serving as a current collecting electrode. When the current collecting electrode is used as the end plate electrode for assembling a stack, electrolyte leakage is avoided. |
