Abstract

A current collector for a planar fuel cell assembly comprising a plurality of planar fuel cells, the current collector comprising a flexible foil of electrically non-conductive material comprising first and second patterns of electrically conductive material provided on a first and second side thereof, respectively. The first pattern connects the fuel cells in series when the flexible foil is folded over the fuel cells. The second pattern conveys the electrical energy generated in the planar fuel cells to an output terminal.
