Abstract:
1. A hydrogen control system for a generator housing, the hydrogen control system comprising: a purity monitoring system (PMS) operatively connected to the generator housing and configured to monitor environmental conditions in the generator housing; a mass flow control system operatively connected to the PMS and fluidly connected to an outlet of the generator housing for extracting a gas mixture from the generator housing, the mass flow control system configured to measure a flow rate of the extracted gas mixture and modify the flow rate of the extracted gas mixture across a range of flow rates via at least one mass flow control valve, wherein the mass flow control system includes a solenoid valve fluidly connected to the generator housing, the mass flow control system further configured to open the solenoid valve and close the at least one mass flow control valve in response to the at least one mass flow control valve failing to perform the modifying of the flow rate of the extracted gas mixture across the range of flow rates; and a vent conduit fluidly connected to an outlet of the mass flow control system, the vent conduit for receiving a portion of the extracted gas mixture from the mass flow control system and feeding the portion of the extracted gas mixture to ambient.
