An integrated cooling module of a fuel cell stack is attached to a housing of the fuel cell stack, and the integrated cooling module is connected to a plurality of components constituting a thermal management system of a fuel cell. In particular, the integrated cooling module includes: a first injection member defining flow paths guiding coolant into one or more components of the thermal management system of the fuel cell, and at least one second injection member coupled to the first injection member, and the coolants going through the components flow into the fuel cell stack through any one of the flow paths defined by the integrated cooling module.

A solid oxide cell assembly includes a housing that further includes a base plate, a cover and one or more side walls. one or more solid oxide cell stacks are positioned on the base plate. at least one radiant heater element is positioned inside the housing and is configured to emit radiant heat onto the one or more solid oxide cell stacks. the at least one radiant heater element is formed as one of a heating tube and a heating plate and comprises a plurality of separately controllable segments each comprising separate power connections. The solid oxide cell assembly is further formed as a high temperature electrolysis cell assembly.

A cooling control method of a fuel cell is provided. The method includes estimating a temperature of a separator based on heat exchange between the separator formed between unit cells of a fuel cell stack and coolant flowing through a cooling line between the separators. A ratio of coolant passing through a heat exchange device to coolant bypassing the heat exchange device is adjusted based on the estimated temperature of the separator. Additionally, a rotation speed of a pump for circulating coolant for cooling the fuel cell stack is adjusted based on the estimated temperature of the separator.

An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.

A fuel cell system includes: a reformer which generates a reformed gas containing hydrogen by reacting hydrocarbon and moisture with each other; a fuel cell stack which generates electric energy through electrochemical reaction of the reformed gas and an oxidant; an ejector which, using steam as a drive fluid, sucks either a raw fuel containing the hydrocarbon or a recycled gas recovered from an anode exhaust gas, and supplies a resultant gas to the reformer; and a vaporizer which generates the steam by vaporizing water, wherein an operation temperature of the fuel cell stack is higher than a boiling point of water at an operation pressure, and the vaporizer generates the steam through heat exchange with the anode exhaust gas.

In order to prevent injury from hot exhaust gas, water is condensed by a metal net in the exhaust pipe.

An air pressure in fuel cells of an electric power generation system comprising a fuel cell stack (PCS) is raised with a pressurized air cooling system with recirculation to values at least two times greater than typical values for an PCS with air cooling. The FCS is either placed in a high-pressure chamber to which air is injected, or air outgoing from the FCS is redirected via a duct back to the FCS inlet and a portion of pressurized fresh air is added thereto. The chamber or the duct is provided with a radiator by means of which circulating air heat is transferred into the external environment. Air recirculation in the chamber or the duct is effected by means of fans for cooling fuel cells. Useful capacity of electric power generation systems based on fuel cells is raised significantly, the necessity of using a humidifier is excluded, and the temperature range of fuel cell operation is expanded.

A system and method for cooling and humidifying a cathode subsystem of a fuel cell for an automobile. The system includes a compressor, an air input line including an intercooler configured to cool air output by the compressor, a fluid output line including a fluid injection system, a cathode stack configured to receive air via the air input line and output a fluid to the fluid output line, and an electronic processor. The electronic processor is configured to control the fluid injection system such that the fluid output from the cathode stack is injected into the air input line.

The present disclosure relates to a thermal management system and method of adjusting and/or reversing coolant flow of a fuel cell system during stationary applications.
