Racked power supply ventilation

Abstract

A ventilation system for a fuel cell power module is provided. The ventilation system includes a ventilation enclosure for evacuating fluids from the fuel cell power module, the ventilation enclosure having an air inlet for providing ingress of air to the enclosure. The ventilation system further concludes a ventilation shaft in fluid communication with the ventilation enclosure and an evacuation pump arranged to exhaust fluid from the ventilation enclosure to a desired location.

         22 . A ventilation system for an electric energy generating system comprising:
 a frame for supporting at least one fuel cell power module;   an enclosure for enclosing the at least one fuel cell power module; and   a vent shaft for fluidly connecting with said at least one fuel cell power module to facilitate ventilation of any fluids therefrom.   
     
     
         23 . (canceled) 
     
     
         24 . The ventilation system of  claim 22  further comprising an evacuation pump in communication between the enclosure and the vent shaft. 
     
     
         25 . The ventilation system of  claim 22  further comprising a pressure sensor in the enclosure. 
     
     
         26 . The ventilation system of  claim 25  in comprising a control unit located outside of the enclosure, the control unit being communication with the pressure sensor. 
     
     
         27 . The ventilation system of  claim 22  further comprising a pressure differential sensor arranged to measure a pressure differential between the inside of the enclosure and the ambient atmosphere. 
     
     
         28 . The ventilation system of  claim 22  wherein the enclosure further comprises a condensation vessel for collecting water condensing inside the enclosure. 
     
     
         29 . The ventilation system of  claim 28 , wherein the condensation vessel comprises a water purge valve selectively operable between a closed state and an open state, for selectively emptying condensate water from the condensation vessel. 
     
     
         30 . The ventilation system of  claim 29 , wherein the condensation vessel further comprises a water over-run aperture. 
     
     
         31 . The ventilation system of  claim 24  wherein a system control unit regulates the speed of the evacuation pump according to the pressure differential between the ventilation enclosure atmosphere and ambient atmosphere to preserve the pressure differential to below a pre-set value. 
     
     
         32 . The ventilation system of  claim 20 , wherein the ventilation system is arranged in a building and a fresh air inlet to the ventilation system is arranged to draw air from outside the building.
