A fuel cell system includes a fuel cell assembly that includes a plurality of individual fuel cells, each fuel cell having an electrolyte medium, a cathode and an anode; and at least one centrifugal blower system for providing a flow of gaseous medium to the fuel cell assembly. The centrifugal blower system includes a series of blower units, each blower unit in the series comprising a casing having an axial inlet and a radial outlet, an impeller disposed within the casing for drawing a gaseous… Show more

A fuel cell system includes a fuel cell assembly that includes a plurality of individual fuel cells, each fuel cell having an electrolyte medium, a cathode and an anode; and at least one centrifugal blower system for providing a flow of gaseous medium to the fuel cell assembly. The centrifugal blower system includes a series of blower units, each blower unit in the series comprising a casing having an axial inlet and a radial outlet, an impeller disposed within the casing for drawing a gaseous medium at a first pressure in the axial inlet and expelling gaseous medium at a second higher pressure through the radial outlet, and a motor for driving the impeller; and a duct connecting the radial outlet of at least one blower unit in the series of blower units with the axial inlet of at least one successive blower unit in the series of blower units.

A wireless sensor includes at least one undulating electrical conductor. The undulating electrical conductor(s) extends along a spiral path between its first end and second end that remain electrically unconnected. Each undulating electrical conductor has inductance and capacitance wherein, in the presence of a time-varying magnetic field, the undulating electrical conductor(s) resonates to generate a harmonic response.

CO-Inventor of a compact centrifugal blower system to be used in fuel-cell electrochemical process control. Developed hardware and control software/electronics and produced complete solution. This system ties together off-the-shelf components and rapid prototype/injection molded components in an extremely lightweight, power-efficient, reliable, and cost effective design. The patent covers different configurations of centrifugal blower systems, as well as optimized low-flow and high-flow control… Show more
