Latest Patents

One of his latest patents is titled "Slip stream for reliable anode to cathode flow in freeze conditions." This invention provides a device and method for ensuring proper fuel cell system warmup or shutdown during freeze conditions. A three-way valve is utilized in conjunction with a flow-controlling orifice to prevent ice blockage during frozen conditions. The system delivers dry, warm air as a slip stream under pressure to the cathode flowpath. The orifice is designed to be structurally compliant, promoting flexing in response to the pressurized slip stream, which helps to break up any small amount of ice that may have formed.

Another notable patent is "Extended valve orifice for fuel cell." This improved fuel cell system includes a component designed to minimize or prevent the collection of water, thus reducing the formation of ice at low temperatures. The system is configured to operate under freeze start conditions, and various methods are provided for controlling ice blockage in a fuel cell system.
