摘要： An electrochemical cell utilizes an air flow device that draws air through the cell from a scrubber that may be removed while the system is operating. The negative pressure generated by the air flow device allows ambient air to enter the cell housing when the scrubber is removed, thereby enabling continued operation without the scrubber. A moisture management system passes outflow air from the cell through a humidity exchange module that transfers moisture to the air inflow, thereby increasing the humidity of the air inflow. A recirculation feature comprising a valve allow a controller to recirculate at least a portion of the outflow air back into the inflow air. The system may comprise an inflow bypass conduit and valve that allows the humidified inflow air to pass into the cell inlet without passing through the scrubber. The scrubber may contain reversible or irreversible scrubber media.

摘要： A hydrogen storage system for detecting and restricting a pressure difference generated in the hydrogen storage system and a method for adjusting differential pressure therein are provided. The hydrogen storage system includes a controller that controls valves of a plurality of tanks. The controller measures pressure for each tank, measures a pipe pressure of pipe connected with the plurality of tanks, compares the pressure for each tank with the pipe pressure to determine whether differential pressure between the tank and the pipe is generated, determines whether it is expected to generate differential pressure between the tanks in an expected equilibrium temperature, when it is determined that the differential pressure between the tank and the pipe is not generated, and performs pressure equilibrium control between the tanks, when it is expected to generate the differential pressure between the tanks.
