Fuel-cell battery unit containing a number of fuel-cell blocks. The fuel-cell blocks are attached to a beam having an I-shaped cross-section, on both sides against the thin intermediate section thereof. Primary ducts for supplying air, fuel and electrolyte are provided either in the wide top and bottom parts of the beam, or separately alongside the beam. From these primary ducts secondary tubes are provided to supply or discharge air, fuel and electrolyte to or from the fuel-cell blocks. A number of such units can be stacked to form a battery or battery section. |
