Abstract

The present invention relates to a flow field plate for use in a stack of fuel cells, which comprises at least one flow field plate (1, 9) of electrically conductive material and a meander electric assembly (MEA) (39) at each side of the bipolar electrode, wherein the bipolar electrode consists of a plate (1) mounted in an electrically insulating sealing frame (9), which is provided with channel portions (12, 32), each one connecting an arbitrary valley (4, 24) at an arbitrary side of the plate (1).
