Latest Patents
Sumi's latest patents include a manufacturing method and manufacturing apparatus for a fuel cell unit. The manufacturing method involves a stacking step and a laser irradiation step. In the stacking step, a stacked portion, which includes a resin frame member of a resin frame equipped membrane electrode assembly and an outer peripheral portion of a separator, is placed on a metal spacer. The resin frame member at a joining target portion of the stacked portion is positioned to face a recess of the metal spacer. During the laser irradiation step, the separator at the joining target portion, where the resin frame member faces the recess, is irradiated with a laser beam. This process forms a welded portion where the resin frame member and the separator are bonded together. Additionally, Sumi has developed a fuel cell that includes a frame equipped membrane electrode assembly and a metal separator. The frame equipped membrane electrode assembly consists of a membrane electrode assembly and a frame-shaped insulating member connected to it. The metal separator comprises a first bipolar plate and a second bipolar plate joined together, with the frame-shaped insulating member featuring a welding portion that is welded to the first bipolar plate through resistance welding.
