Abstract (en)

[origin: WO2006068527A2] The following invention includes a fuel cell stack where the fuel is hydrogen, the electrolyte is in the solid state and is a polymeric membrane which allows for the cationic exchange but not the electronic exchange, designed for the feeding only of hydrogen and air, designed for electricity production, where: at the anodes, the hydrogen' s dissociation in protons and electrons takes place; at the membranes, the protons are driven from the anodes to the cathodes; at an outer circuit, the electrons are driven from the anodes to the cathodes; and, at the cathodes, the recombination of protons, electrons and oxygen atoms takes place into water molecules. It is characterized by comprehending a bipolar diffusion plate 1, where on one side channels 3 and 4 are drawn for the hydrogen feeding, channels 3 and 4 enclosing, together with the polymeric membrane, a tight chamber who allows the dead-ended operation of the device under a fixed pressure, without any fuel recirculation; and on the other side are drawn the axial channels 5 for an easy air circulation, channels 5 eventually forming a perpendicularly intertwined grid helping a natural air feeding.
