Abstract

A method of manufacture is provided during which a first material layer (62A) is disposed with a second material layer (64) to provide a multi-layered preform (60). The first material layer (62A) lengthwise and widthwise overlaps the second material layer (64). The first material layer (62A) is configured from or otherwise includes a titanium material. The second material layer (64) is configured from or otherwise includes an aluminum material. The multi-layered preform (60) is clamped between a first die (66) and a second die (68). The first die (66) and the second die (68) each lengthwise and widthwise overlap the multi-layered preform (60). The multi-layered preform (60) clamped between the first die (66) and the second die (68) is sintered and bonded to provide a bipolar plate (36; 38) for a fuel cell (28). The titanium material in the first material layer (62A) of the bipolar plate (36; 38) is bonded to the aluminum material in the second material layer (64) of the bipolar plate (36; 38) during the sintering of the multi-layered preform (60).
