Abstract
Systems and methods are provided for actively directing hydrogen flow in an electrochemical cell system. The electrochemical cell system includes a component configured to receive hydrogen gas, one or more hydrogen blower assemblies positioned upstream and/or downstream of the component. The one or more hydrogen blowers include at least one sensor positioned on an outer surface of the one or more hydrogen blower assemblies and a controller including instructions to generate a notification in response to an output of the at least one sensor being outside of a target range.
Claims20
An electrochemical cell system, comprising:
- one or more hydrogen blower assemblies, wherein the one or more hydrogen blower assemblies are positioned in line with a hydrogen passage of the electrochemical cell system, and
- wherein the one or more hydrogen blower assemblies include at least one sensor positioned on an outer surface of the one or more hydrogen blower assemblies;
- and
- a controller, including executable instructions stored on non-transitory memory that, when executed, cause the controller to:
- generate a notification in response to an output of the at least one sensor being outside of a target range.
A method of operating an electrochemical cell system, comprising:
- responsive to a demand for hydrogen gas at a component of the electrochemical cell system, energizing a hydrogen blower assembly to rotate an impeller of the hydrogen blower assembly;
- adjusting a flow rate of the hydrogen gas by modifying a power supplied to a driver of the hydrogen blower assembly to vary a rate of rotation of the impeller;
- responsive to an output of a sensor or an input of the hydrogen blower assembly being outside of a target range, adjust an operating condition of the electrochemical cell system and/or generate a notification.
An electrochemical cell system, comprising:
- at least one hydrogen gas storage container;
- a component demanding hydrogen gas from the at least one hydrogen gas storage container;
- a hydrogen blower assembly configured to pump hydrogen from the at least one hydrogen gas storage container to the component, wherein the hydrogen blower assembly includes an impeller positioned inside a hermetically sealed housing and a driver positioned outside of the hermetically sealed housing;
- and
- a controller, including executable instructions stored on non-transitory memory that, when executed, cause the controller to:
- energize the driver of the hydrogen blower assembly in response to a demand for hydrogen gas by the component, and
- in response to a flow rate of hydrogen being outside of a target range, adjust a power delivered to the driver of the hydrogen blower assembly.
