The systems and methods described herein provide for a hydrogen generation system that includes one or more gas-detecting sensors for measuring the concentration of gases within or associated with the hydrogen generation system. The obtained measurements may be utilized for many purposes by a controller or control system of the hydrogen generator. When such concentrations are measured, one or more remedial actions may be executed on the generator to prevent the unsafe operating condition. Further, many such safety gas sensors may be associated with a corresponding redundant gas sensor such that measurements from the gas sensor and the redundant gas sensor may be compared to determine a difference between the two measurements which may indicate an operational state of the hydrogen generator. The gas measurements from the sensors may also be analyzed to obtain data and information of an operational status of the hydrogen generator.
