Abstract:

A method is provided for welding workpieces together while minimizing distortion in those workpieces. That method includes loading the workpieces to be welded together into a periphery clamp welding fixture. This is followed by tack welding the workpieces together by means of spot welds. Next is the removing of a portion of the welding fixture in order to provide an open field with respect to the workpieces and then completing welding of the workpieces together in the open field. Thus, the entire weld process may be completed utilizing a single periphery clamp welding fixture.

Abstract:

Improved bipolar plates comprising complex features can be manufactured for fuel cells in a simple, low cost manner by starting with an appropriate extruded piece. The complex features include one or more fluid ports which connect to channels internal to the bipolar plate. The method includes extruding a continuous sheet with appropriate linear channels on each surface of the sheet as well as within the sheet, transversely cutting the sheet, machining a fluid port or ports through the sheet to intersect with appropriate internal linear channels, machining at least two sealing ports through the sheet to intersect with the internal linear channels on opposite sides of the fluid ports, and applying sealant into the sealing ports in order to make appropriate seals to the internal linear channels.
