Systems, devices, and methods for electrolysis at very large scale (e.g., exceeding 100 megawatts (MW), and at gigawatt (GW) scale having a solid oxide electolyzer cell (SOEC) system including one or more SOEC columns, and one or more heat exchangers, each of the heat exchangers configured to receive input stream that is used to heat respective SOEC columns, wherein each of the heat exchangers is located along respective SOEC columns such that the input steam exiting the heat exchanger is directed towards adjacent SOEC columns.

SOEC integration with ultra hot steam

A method of operating a vessel includes providing hydrogen or a fuel mixture containing hydrogen and a hydrocarbon fuel to a power generator disposed on the vessel, and providing power from the power generator to an electrical load of the vessel.

A fuel cell stack module includes a base, a cover dome removably positioned on the base, and a plurality of fuel cell stacks removably positioned on the base below the cover dome. A modular fuel cell system includes a plurality of the fuel cell stack modules, where each fuel cell stack module may be electrically disconnected, removed from the fuel cell system, repaired or serviced without stopping an operation of the other fuel cell stack modules in the fuel cell system.

Modular fuel cell system

A method for charging electric vehicles includes receiving information regarding an electric vehicle. At least a portion of the information is received through a vehicle interface configured to place a battery of the electric vehicle into electrical communication with a fuel cell system. A charge is delivered from the fuel cell system to the battery of the electric vehicle through the vehicle interface without use of a direct current to alternating current (DC/AC) converter. The charge is delivered based at least in part on the information.

Fuel cell system for charging an electric vehicle

A method of making a solid oxide fuel cell (SOFC) includes providing a solid oxide electrolyte and depositing at least one electrode on the electrolyte by PVD, such as sputtering. A method of making an interconnect for a fuel cell stack includes providing an electrically conductive interconnect, and depositing a layer on the interconnect by PVD, such as depositing a LSM barrier layer by sputtering. The SOFC and the interconnect may be located in the same fuel cell stack.

Coating process for production of fuel cell components

A method of operating a high temperature fuel cell system containing a plurality of fuel cell stacks includes operating one or more of the plurality of fuel cell stacks at a first output power while operating another one or more of the plurality of the fuel cell stacks at a second output power different from the first output power.

Increasing thermal dissipation of fuel cell stacks under partial electrical load

A method of operating a fuel cell electrochemical system includes receiving at least one of a cost of electricity and a cost of fuel and adjusting at least one of an operating efficiency and throughput of the fuel cell based on the at least one of the received cost of electricity and the received cost of fuel.

Method of optimizing operating efficiency of fuel cells

A method in which a high temperature electrochemical system, such as a solid oxide fuel cell system, generates hydrogen and optionally electricity in a fuel cell mode. At least a part of the generated hydrogen is separated and stored or provided to a hydrogen using device. A solid oxide regenerative fuel cell system stores carbon dioxide in a fuel cell mode. The system generates a methane fuel in an electrolysis mode from the stored carbon dioxide and water by using a Sabatier subsystem. Alternatively, the system generates a hydrogen fuel in an electrolysis mode from water alone.
