Abstract: A system and method for accomplishing localized feature forming in a sheet of material and/or the localized joining of multiple sheets of material. The system and method may also be used to attach a secondary component to a sheet of material. The system and method of the present invention employs a die having a shaped cavity for receiving a portion of the sheet material. A projectile is propelled from a projectile firing device to impact the sheet or sheets of material in the area overlying the subjacent die cavity. The projectile forces a portion of the sheet material into the die cavity, imparting a shape thereto. The kinetic energy transferred from the projectile to the sheet material may be used to form a metallurgical bond between multiple sheets of material. The metallurgical bond can be used alone to join the sheets, or may be used in conjunction with an interlocking shape to provide extra strength.

Abstract: A scheme for electromagnetic formation of fuel cell plates is provided. In accordance with one embodiment of the present invention, a method of forming a flow field plate is provided where an electromagnetic actuator is arranged opposite a profiled surface of a die portion. The profiled surface of the die portion is configured to at least partially define a network of flow field plate flow passages. The electromagnetic actuator is configured to generate a magnetic field upon activation and a sheet of material is positioned between the electromagnetic actuator and the profiled die surface. The sheet of material is characterized by an electrical conductivity sufficient to yield a repulsive electromagnetic force between the actuator and the sheet upon activation of the actuator. The passages are formed by driving the electromagnetic actuator such that the repulsive force is of sufficient intensity to deform the sheet against the profiled die surface.
