Methods of and systems for filtering particles, whose largest cross-sectional dimension is greater than a predetermined distance, of a multiphase fluid that comprises a particulate phase are provided. The methods provide for a step for delivering the multiphase flowable fuel through filter means, wherein the filter means is for retaining particles of the particulate phase whose largest cross-sectional dimension is greater than a predetermined distance. The systems provide for means for retaining particles whose largest cross-sectional dimension is greater than a predetermined distance, and means for providing at least one flow path for at least part of the multiphase fluid. In one application, the methods and systems are used in connection with an electrochemical power source and components thereof.

An electrical battery for multi-cellular interconnection in series, parallel or series and parallel has a protrusion and a recess, such as a tongue and a groove, extending on outer surfaces of the sidewalls of the battery case such that when a protrusion of one battery is slid into a recess of another, the two batteries are electrically connected by the portions of the protrusion and the recess that are made of electrically conductive materials connected to the voltage producing elements inside the case. The battery further includes hollow plug-in posts and plug-in pins at the top and the bottom of the case that are connected to the voltage producing elements of the battery so that when the plug-in pins of one battery are inserted into the plug-in posts of another, the two batteries are in electrical interconnection. The battery also includes an electrolyte recirculation, gas purging, and automatic watering systems.

A circulation system for a flowing-electrolyte battery having at least one electrochemical cell, an anolyte reservoir, and a catholyte reservoir. The circulation system includes an anolyte pump coupled in fluid flowing relationship to the anolyte reservoir which pumps anolyte from the anolyte reservoir to the at least one electrochemical cell. A catholyte pump is coupled in fluid flowing relationship to the catholyte reservoir and also pumps catholyte to the at least one electrochemical cell. A second phase pump is coupled in fluid flowing relationship to the catholyte reservoir and is used to introduce second phase electrolyte into the aqueous catholyte pumped by the catholyte pump. The second phase pump is controlled by a controller so that the second phase is introduced into the catholyte stream in a metered fashion. A controllable four-way valve is coupled in fluid flowing relationship to the catholyte pump and operable to direct the flow of catholyte through the electrochemical cell in a first direction, and periodically reverse the flow of the catholyte in a second direction. Metering the amount of second phase injected into the catholyte stream and reversing catholyte flow improve battery efficiency.
摘要:
The present invention relates to a process for operating a regenerative fuel cell (RFC). The process involves circulating a first electrolyte (electrolyte 1) through the negative chamber of the cell and a second electrolyte (electrolyte 2) through the positive chamber of the cell. Electrolyte (1) contains sulfide during the discharge cycle of the cell. Electrolyte (2) contains bromine during the discharge cycle of the cell. Decreases in ph in the electrolyte are compensated by circulating a fraction of other electrolyte (1) or (2) through the positive chamber of an auxiliary cell. A fraction of electrolyte (2), which has been made free of bromine, is circulated in the negative chamber of the auxiliary cell.

A fuel cell includes a reaction chamber, at least one fuel chip stored in the reaction chamber, an electrolyte chamber communicated with the reaction chamber, electrolyte installed in the electrolyte chamber. The control element is movable between a first position and a second position. In the first position, the control element avoids the electrolyte flowing from the electrolyte chamber into the reaction chamber. In the second position, the control element allows the electrolyte to flow from the electrolyte chamber into the reaction chamber for reacting with the fuel chips for generating electricity. Alternatively, a pump is used to for pumping vapor into the reaction chamber for reacting with the fuel chips for generating electricity.
