Monopolar fuel cell pack (10) with at least two proton exchange membrane fuel cells or fuel cell packs (10) disposed symmetrically around an intermediate layer (200). The fuel cell pack (10) includes a plurality of cells each having a proton exchange membrane (20a,20b) in its middle and a cathode and an anode at both sides of the membrane, collector plates (14a,14b,13a,13b) contacting the cathode and the anode, respectively, in each cell, which act as monopolar electrodes at the respective anode and cathode. The cells are evenly disposed on an arbitrary plane with a hollow (18) interposed between two adjacent cells and an electrical connection member (15) for electrically connecting the cathode collector plate 14a resp. 14b of one cell to the anode collector plate 13a resp. 13b of the other cell is disposed within the hollow (18). The fuel cell pack also includes a porous fuel diffusion member |
