A fuel cell system and method for using a peak shaving gas, the system including: a fuel inlet configured to receive fuel from a fuel source; a catalytic partial oxidation (CPOx) reactor configured to at least partially oxidize the fuel during startup of the system; a blower configured to provide air to the CPOx reactor; a gas analyzer configured to determine a composition of fuel provided to the CPOx reactor from the fuel inlet; an oxidation catalyst configured to reduce an Ocontent of fuel received from the CPOx reactor; a reforming catalyst configured to partially reform fuel received from the oxidation catalyst; and a stack of fuel cells configured to generate electricity using fuel received from the reforming catalyst.

Solid oxide fuel cell system and method of operating the same using peak shaving gas

A method of operating an electrolyzer module includes providing a first air stream and steam into a stack of electrolyzer cells located in a hotbox and outputting a product stream containing hydrogen and steam, and an oxygen exhaust stream, providing the product stream to an internal product cooler (IPC) heat exchanger located in the hotbox to reduce the temperature of the product stream by transferring heat to the first air stream, and providing the product stream from the IPC to an external product cooler (EPC) heat exchanger located outside of the hotbox and inside of a cabinet housing the hotbox to further reduce the temperature of the product stream by transferring heat to a fluid stream.

Electrolyzer cell module and method of operating thereof using separate stack air flow and product cooling flow

A method for operating a fuel cell system includes drawing a base level DC electric energy from a first fuel cell of a first type to a combined DC bus, measuring a DC voltage at the combined DC bus, determining whether the DC voltage at the combined DC bus falls short of a DC voltage threshold, and drawing a variable DC electric energy from a second fuel cell of a second type different from the first type in response to determining that the DC voltage at the combined DC bus falls short of the DC voltage threshold.

Hybrid fuel cell system for load following and backup in a microgrid and method of operating thereof

A fuel cell system includes at least one of plural electrochemical pump separators to separate carbon dioxide from a fuel exhaust stream or a combination of a gas separator and a fuel exhaust cooler located outside a hotbox.

Solid oxide fuel cell system with hydrogen pumping cell with carbon monoxide tolerant anodes and integrated shift reactor

An integrated power generation and exhaust processing system includes a fuel cell system configured to generate power and to separate COincluded in exhaust output from the fuel cell system, and an exhaust processing system configured to at least one of sequester or densify COseparated from the exhaust output from the fuel cell system.

Integrated power generation, carbon dioxide separation and downstream processing system and method

Various systems and methods disclosed herein may include a fuel cell system that may dynamically respond to changes in steam concentration in the fuel cell system. The fuel cell system may include a fuel cell stack that produces an anode exhaust stream, an anode recycle blower that receives the anode exhaust stream and outputs an anode recycle stream, and a humidity sensor configured to measure the steam concentration of the anode recycle stream. The fuel cell system may also include a master controller configured to receive steam concentration measurement from the humidity sensor and control the operation of the anode recycle blower and/or other components based on the steam concentration measurement.
