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
A hydrogen blower assembly, comprising;
- a hermetically sealed housing;
- an impeller positioned within the hermetically sealed housing, a stem of the impeller coupled to the hermetically sealed housing by suspended bearings;
- and
- a driver positioned outside the hermetically sealed housing and configured to rotate the impeller to propel hydrogen gas.
A hydrogen blower assembly, comprising:
- a housing formed of a first housing piece and a second housing piece, wherein the first housing piece and the second housing piece are substantially the same shape;
- an impeller suspended within the housing, wherein the impeller is symmetric a radial axis;
- and
- a driver configured to couple to an outer surface of the first housing piece and the second housing piece.
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;
- and
- a hydrogen blower assembly configured to pump from at least one hydrogen gas storage container to the component, wherein the hydrogen blower assembly is comprised of a symmetrical impeller including a first stem and a second stem.
