The assembly includes a pair of heat exchangers, each including an upper and lower manifold, parallel and spaced relative to one another. Tubes extend between each set of upper and lower manifolds with fins disposed between each of the tubes. A valve system controls fluid flow between the upper manifolds and the lower manifolds. The valve system is movable between a maximum cooling mode with fluid flow form the first upper manifold through both of the tubes and to said first lower manifold. A temperate mode allows fluid to flow from the first upper manifold to the first lower manifold and from the second upper manifold to the second lower manifold to prevent flash fogging. A maximum cooling mode allows fluid to flow from the second upper manifold through both of the first and second tubes to the lower manifolds.

Secondary loop-integral heater core and cooler

An SOFC stack module including an integral individual stack manifold containing all of the gas pathways necessary for supply and exhaust of fuel gas and cathode air to and from the stack chimneys. The stack is mounted and hermetically joined directly to the manifold without an intermediate base plate. Flanges at the inlet and outlet ports couple to system distributary manifolds via high temperature sealing joints. The manifold preferably is fabricated of a ferritic stainless steel, and may be formed in a one-piece casting, a combination of multiple castings and stamped plates metallurgically joined (brazed or welded together), or stamped from sheet metal stock. Preferably, the manifold includes fin structures extending into adjacent fuel gas and cathode air chambers to enhance balancing of temperatures by heat exchange therebetween. Heat exchange may be further improved by configuring the manifold to have a plurality of interleaved anode and cathode gas supply chambers.

An integrated electrical generator/starter and air conditioning compressor device driven by a common drive shaft, or other direct linkage. The device includes an electrical generator/starter and a compressor. The electrical generator/starter is coupled to the drive shaft. The compressor is coupled to the electrical generator/starter and to the drive shaft and acts to pressurize a flow of refrigerant in response to rotation of the drive shaft. The electrical generator/starter is operable in first and second states. In the first state, the electrical generator/starter generates electricity in response to rotation of the drive shaft. In the second state, the electrical generator/starter utilizes electrical power from a battery to rotate the drive shaft.

A fuel cell system is disclosed. A fuel cell stack is in fluid communication with a reformer. An air conditioning system is in fluid communication with the reformer. Methods of making and using a fuel cell system are also disclosed.

Water recovery for a fuel cell system

A heating, venting, and air conditioning system utilizes a reformer to provide supplemental heat to a passenger compartment and to improve start-up emissions of an engine of a vehicle or power system. A pump circulates a fluid through the engine and throughout the system. A radiator and heater core transfer heat from the fluid. A first circuit cools the fluid upon circulation through the radiator after circulation through the engine to cool the engine, and a second circuit heats the passenger compartment and cools the fluid upon circulation through the heater core after circulation through the engine to cool the engine. The reformer, which converts a hydrocarbon or alcohol fuel into a reformate, generates heat. A third circuit, defined between the reformer and the pump and interconnected with the heater core, provides the supplemental heat from the reformer to the passenger compartment through the heater core and also to the engine.

Heating, venting, and air conditioning system for providing supplemental heat in a vehicle

A method of starting a solid oxide fuel cell system is disclosed. The method comprises pressurizing a main plenum to a first pressure. The main plenum comprises a first supply of fuel, blowers, and air control valves. The first supply of fuel and a first supply of air are directed to a preheated micro-reformer. A heated pre-reformate is created in the micro-reformer and discharged from the micro-reformer to a main reformer. The main reformer is preheated with the heated pre-reformate. A second supply of fuel and a second supply of air are introduced to the main reformer. A heated main reformate is created in the main reformer and directed to a waste energy recovery assembly. A cathode supply is heated in the waste energy recovery system and then directed to a solid oxide fuel cell stack in order to heat the solid oxide fuel cell stack. Methods of transitioning, operating, shutting down, and maintaining in standby mode are also disclosed. A solid oxide fuel cell mechanization for a transportation vehicle is also disclosed.

Integrated solid oxide fuel cell mechanization and method of using for transportation industry applications

An assembly is provided to increase the efficiency of a vehicle engine cooling and supplementary, heat pump type cabin heating system. A flexible panel located in front of and below the front end heat exchanger can be moved between open and blocking positions. An engine cooling radiator and fan are located behind the front end heat exchanger. In cold weather heating mode, the flexible panel can be rolled to the blocking position, preventing the direct flow of cold outside ram air through the front end heat exchanger. At the same time, the fan is reversed, flowing heated air from the radiator through the front end heat exchanger, improving its efficiency.

Reduces the risk of internal fogging of the windscreen.
