An alternating current (AC) impedance spectroscopy method includes providing an AC impedance spectroscopy ripple from power electronics into an electrochemical device, and absorbing the ripple in the power electronics.

Impedance monitoring of a modular electrolysis system

A method includes providing raw water into a first filter assembly to remove solids from the raw water to form a filtrate, providing the filtrate from the first filter assembly into a second filter assembly to electrochemically remove ionics from the filtrate to form purified water, and providing the purified water to an electrolyzer to generate hydrogen by electrolyzing the purified water.

An air decontamination device () comprising: an input unit (); an output unit (); and a decontamination unit () coupled at a first end () to the input unit () and coupled at a second end () to the output unit (). The decontamination unit () comprises: pairs of conducting plates (), where one conducting plate of each pair is for being positively charged and the other conducting plate of each pair is for being negatively charged. The positively charged plate and negatively charged plate are separated to form an airflow path () and a 3D material () that is capable of being potentiated by static electric field is coupled to each side of conducting plate (). When the static electric filed is applied, the surface moieties of the 3D material () are realigned to a direction of the static electric field to potentiate the antimicrobial activity of the 3D material () for destroying the microbes present in the received air.

The present invention discloses a system and a method for resource data classification and management. In operation, the present invention provides for evaluating a deployment probability score for each incoming data-record based on previous data-records. Further, a match score of each incoming data-record is computed. Furthermore, each incoming data-record is analyzed to determine a bench period associated with each incoming data-record. Yet further, the present invention, categorizes the incoming data-records into two or more categories based on corresponding deployment probability score, match score and bench period. A deployment opportunity index is generated for each incoming data-record representing the categories and corresponding probability score, match score and bench period, providing an upfront indication of deploy-ability of an incoming data-record. Finally, the present invention provides for generating a list of recommendations for each data-record.

A fuel cell system includes grid independent operation with DC microgrid capability. This fuel cell system has a capability of operation with and without the grid, and with DC micro-grid capability.

Fuel cell system with grid independent operation and DC microgrid capability

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 providing electrical power using a split bus configuration includes receiving a first direct current at a positive bus of a split bus, where the first direct current originates from a first fuel cell segment. A second direct current is received at a negative bus of the split bus, where the second direct current originates from a second fuel cell segment. A third direct current is also received at the split bus such that a combined direct current is formed including the first direct current, the second direct current, and the third direct current. The third direct current originates from an alternative direct current (DC) source. The combined direct current is provided to an inverter such that an alternating current is generated for a load.

Integrated fuel cell system with auxiliary power delivery

A method includes receiving a direct current (DC) signal at an inverter control system from a bus. The inverter control system includes an inverter and an inverter controller. The received DC signal is compared to a reference value. Based at least in part on the comparison, the inverter controller determines whether to adjust a magnitude of the DC signal received through the bus. The DC signal is converted to an alternating current (AC) signal with the inverter, and the AC signal is provided to a load.

Fuel cell control system

Systems, methods and devices for power generation systems are described. In particular, embodiments of the invention relate to the architecture of power conditioning systems for use with fuel cells and methods used therein. More particularly, embodiments of the present invention relate to methods and systems usable to reduce ripple currents in fuel cells.

Ripple cancellation

A method for starting up a fuel cell arrangement includes receiving a first electrical signal from an alternative power source. At least a portion of the first electrical signal is provided to a balance of plant (BOP) load, where the BOP load is in electrical communication with a fuel cell system. It is determined whether a startup threshold of the fuel cell system is met. If the startup threshold is met, a second electrical signal is provided from the fuel cell system to the BOP load, where a combination of the first electrical signal and the second electrical signal corresponds to a load demand of the BOP load. A value of the second electrical signal is increased and a value of the first electrical signal is decreased until the load demand of the BOP load is met by the fuel cell system.
