Fuel cell plate with variable thickness sealing beads

The fuel cell device, comprising at least two oppositions pillboxes; the plate materials in the same base, and a distribution an elastic sealing welding ball arranged at least one partition plate. The elastic sealing welding beads are line of the liquid between control panel is of the electrolyte is mobile, thereby of called and liquid encapsulated welding ball. Each plate comprises at least two bolt holes; the bolt hole is made of the third the way of the pedestal fixing plates are in the same base. A acts and hole load compensation welding ball the welding ball of hole is separated. The preferred embodiment, the liquid encapsulated welding ball with a consistent; the thickness of the hole compensation welding ball having is less than the thickness of the liquid encapsulated welding ball. Further in one embodiment, the hole compensation welding ball is wider than the liquid encapsulated welding ball. In one embodiment, the thickness of the liquid encapsulated welding ball into the liquid welding ball any component and bolt holes the function of distance, and exchange, the thickness of the compensation welding ball, and adapts to the bolts part usual anticipated high stress load. Therefore, wherein the bolt load proliferates from the uniform the area plate, the invention on the fixing plate with a load the stress distribution improved.
