Patent ID: 8563196

Claim:
An electric energy generating system, comprising: a mounting frame; at least one fuel cell power module mounted to the mounting frame, and having at least one fuel cell stack, each at least one fuel cell stack having an anode inlet for a fuel; a fuel storage vessel in fluid communication with each anode inlet of the at least one fuel cell stack via at least one fuel pipe; a ventilation enclosure for evacuating fluids emanating from the at least one fuel cell power module, the ventilation enclosure encompassing the at least one fuel cell power module to contain fluid egress therefrom, the ventilation enclosure having at least one ventilation air inlet aperture to provide air ingress into the ventilation enclosure; a ventilation shaft in fluid communication with the ventilation enclosure; and an evacuation pump arranged to draw exhaust fluid from the ventilation enclosure through the ventilation shaft and discharge the exhaust fluid away from the electric energy generating system via at least one vent opening in the ventilation shaft, to maintain a pressure within the ventilation enclosure which pressure is lower than ambient pressure by a pre-set value.
