Abstract
Methods of fabricating an interconnect for a fuel cell stack include providing a powder in a die cavity of a powder press apparatus, where the powder includes at least one of a pre-alloyed powder and a pre-sintered powder, compressing the powder in the die cavity of the powder press apparatus using high velocity compaction to form a pressed powder interconnect, and incorporating the pressed powder interconnect into a fuel cell stack, wherein the pressed powder interconnect is incorporated into the fuel cell stack without first sintering the pressed powder interconnect.
