Patent number: 7883809Abstract: A technique for heating a fuel cell stack at stack start-up that includes using the vehicle motor drive system to generate waste heat independent from providing traction. Particularly, at fuel cell stack start-up, the electric traction inverter associated with the traction motor that drives the vehicle is controlled so that command signals provided by an inverter to a traction motor do not provide motor torque, but dissipates power into the motor windings and/or motor structure as waste heat. Thus, the output power generated by the fuel cell stack can be made high enough to quickly heat the fuel cell stack through inefficiencies in the stack operation, without providing driving torque. Additionally, the electric traction inverter can be operated so that waste heat is generated within the semiconductor power switches in the inverter.Type: GrantFiled: August 3, 2005Date of Patent: February 8, 2011Assignee: GM Global Technology Operations LLCInventor: Clark G.

Patent number: 7883810Abstract: A system for the slow purge of a fuel cell stack. A pump can be used to keep the coolant circulating, so that the stack, an associated radiator, and coolant plumbing therebetween are maintained at the same temperature. The heat from the stack, liquid coolant, and radiator can be used to provide the heat of vaporization of the liquid in the stack, and the liquid water can be removed from the stack as water vapor. Because the air flow rate is relatively low, there is sufficient time for the water to vaporize and for the air to come to the same temperature as the stack, which is also facilitated by high surface area for heat transfer. Purge air can be drawn into the stack through the radiator, via a purge air blower, which preheats the air to help avoid frigid air contacting the stack.Type: GrantFiled: November 9, 2006Date of Patent: February 8, 2011Assignee: GM Global Technology Operations LLCInventors: John C.

Patent number: 7883816Abstract: A fuel cell device includes an elongate substrate having a cold zone adjacent a first end and a reaction zone adjacent a second end configured to be heated to an operating reaction temperature while the cold zone is configured to be shielded from the heat source to remain at a low temperature below the operating reaction temperature. Fuel and air inlets positioned in the cold zone are coupled to respective elongate fuel and oxidizer passages that extend within an interior solid ceramic support structure through the reaction zone in parallel and opposing relation to respective outlets adjacent the second end. Electrodes positioned adjacent the passages in the reaction zone are each electrically coupled from the interior structure to respective exterior contact surfaces in the cold zone. A solid electrolyte monolithic with the ceramic support structure is positioned between electrodes, and electrical connections are made to the exterior contact surfaces.Type: GrantFiled: November 8, 2006Date of Patent: February 8, 2011Inventors: Alan Devoe, Lambert Devoe
