Publication number: 20240110419Abstract: An apparatus for mounting a bifold door panel, and allowing the panel to run on a track. The apparatus has a trolley that runs within the track and a vertical elongate member that is axially movable relative to the trolley. A hinge or hinge portion is mounted on the elongate member, and a first support is disposed between the trolley and the hinge or hinge portion. The first support functions to support the hinge or hinge portion against a compression force arising from the bifold door panel when the apparatus is mounted on a top region of the panel. A second support is disposed at or toward the terminus of the elongate member and distal to the trolley. The second support functions to support the hinge or hinge portion against a compression force arising from the bifold door panel mounted thereon when mounted on a bottom region of the panel.Type: ApplicationFiled: September 21, 2023Publication date: April 4, 2024Inventors: Craig Lang, Matthew Keen

Patent number: 9105888Abstract: A combined water drain and diluent gas purge valve routes fluid from the anode side of a fuel cell to the cathode inlet. When a purge of diluent gas is requested, the valve opens, draining any liquid present in the sump of a water separation device, for example. After the liquid has drained, the diluent gas is purged. An anode bleed model using fuel injector feedback can determine the amount of gas exiting the valve, and can request the valve to close once the required amount of diluent is purged. During operation, an amount of hydrogen may exit the valve. Hydrogen passing through the valve can be catalytically consumed once it reaches the cathode electrode, causing the cathode exhaust, and the fuel cell exhaust to have a reduced hydrogen content.Type: GrantFiled: October 7, 2011Date of Patent: August 11, 2015Assignee: GM Global Technology Operations LLCInventors: Steven R. Falta, Matthew A. Lang, Daniel C. Di Fiore

Publication number: 20140335432Abstract: Apparatus, methods, and systems for estimating hydrogen concentration and/or pressure in an anode compartment of a fuel cell stack in a fuel cell vehicle. In some implementations, the estimates are based on a correlation between a transient dip in voltage in response to an anode to cathode bleed event and a concentration of hydrogen in the anode compartment of a fuel cell stack. Some implementations may comprise initiating a bleed event, sensing a transient dip in voltage in response to the bleed event, and using the correlation to calculate an estimate of a concentration and/or pressure of the gas in the anode compartment. The sensitivity of the correlation and hence the accuracy of estimation may change with the power level and may be accounted for in the correlation.Type: ApplicationFiled: May 7, 2013Publication date: November 13, 2014Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: MANISH SINHA, MATTHEW A.

Patent number: 8785071Abstract: A system and method for controlling hydrogen gas flow to an anode side of a fuel cell stack using a pressure regulator in the event that an injector that normally injects the hydrogen gas into the fuel cell stack has failed in a stuck open position. During normal operation, the control of the injector is determined based on the pressure of an anode sub-system and the position of the pressure regulator is determined based on a supply pressure between the pressure regulator and the injector. If it is determined that the injector is stuck in an open position, then the position of the pressure regulator is controlled to the anode pressure instead of the supply pressure. If the pressure regulator is an electrical pressure regulator, then it is pulsed to mimic normal system operation. Alternately, another valve, such as a shut-off valve, can be employed to provide the flow pulsing.Type: GrantFiled: November 3, 2011Date of Patent: July 22, 2014Assignee: GM Global Technology Operations LLCInventors: Steven R.
