ABSTRACT:
An integrated current collector and electrical component plate for a fuel cell stack is disclosed, comprising a printed circuit board comprising the following layers: a current collection layer, comprising a current collector; a first insulation layer, comprising a first surface and a second surface; an electrical component layer, comprising an electrical component having a first connection site and a second connection site; and a second insulation layer, comprising a first surface and a second surface, wherein the current collection layer is laminated to the first surface of the first insulation layer, and the electrical component layer is laminated between the second surface of the first insulation layer and the first surface of the second insulation layer. A fuel cell stack and methods for manufacturing a fuel cell stack comprising the integrated current collector and electrical component plate are also disclosed.
