摘要： An electrolyte chamber assembly (10) for an electrochemical cell 3, the assembly (10) comprising a forward electrolyte flow plate (8) and a rearward electrolyte flow plate 6 that are abutted with each other to form the assembly (10). The inward facing side of each flow plate (6, 8) is provided with an electrolyte inflow channel (15), an electrolyte outflow collector (34) and an electrolyte chamber aperture (14) that are mirror images of the electrolyte inflow channel (15), the electrolyte outflow collector (34) and the electrolyte chamber aperture (14) on the other flow plate (6, 8). The two electrolyte inflow channels (15) create together an electrolyte inflow pipe (16), the two electrolyte outflow collectors (34) create together an electrolyte outflow pipe 32 and the two electrolyte chamber apertures (14) create together an electrolyte chamber (19).

摘要： Described herein are direct liquid fuel cells with an alkaline anodic fuel stream including a solution of liquid fuel such as alcohols, ethers, glycols or compounds of hydrazine, and an acidic cathode oxidant stream including a solution of a suitable oxidant such as hydrogen peroxide or a gas steam with 1% to 100% O2. These cells are used as primary stationary and/or mobile power sources and also function in a secondary role as range extenders when coupled with a primary power source.

摘要： The invention relates to a device for generating electrical power comprising a first electrode having a porosity that allows the flow of an electrolyte solution of concentration CA in a solute; a second electrode having a porosity that allows the flow of an electrolyte solution of concentration CB in a solute, CB being greater than CA; a membrane having selective permeability to anions or cations, said membrane being disposed between the two electrodes and comprising at least one channel arranged to allow the diffusion of electrolytes from the electrolyte solution of concentration CB to the electrolyte solution of concentration CA through said channel or channels; and a device making it possible to harvest the electrical power generated by the differential in potential between the two electrodes, wherein the two electrodes are formed of an activated carbon fabric, and to a method for producing electrical power using such a device.

摘要： A fuel cell stack (10) comprises a plurality of fuel cells each with a chamber (K) for electrolyte with at least one inlet (114) and at least one outlet (116), and an inlet header (45) to supply electrolyte to all the cells in parallel. Each cell comprises a first plate (12) to define the electrolyte chamber (K), a second plate (13) to define an oxidizing gas chamber (0) and a third plate (14) to define a fuel gas chamber (H), each of these plates (12-14) also defining a side chamber (36) adjacent to but sealed from the corresponding chambers (K, 0, H), so the side chambers (36) defines an electrolyte outlet channel. An electrolyte flow channel (15) is also defined above the top portion of and in communication with the electrolyte chamber (K), so electrolyte is supplied from electrolyte supply (45) through openings (56) into the electrolyte chamber (K), flows upwards towards the top of the electrolyte chamber (K), exits said electrolyte chamber (K) via grooves (60), flows along the flow channel (15), breaks up into droplets at lip (68) and falls into the side chamber (36) prior to being expelled via electrolyte outlet (116). This arrangement reduces leakage currents.

摘要： A reformer assembly includes a vortex tube receiving heated fuel mixed with steam. A catalyst coats the inner wall of the main tube of the vortex tube and a hydrogen-permeable tube is positioned in the middle of the main tube coaxially with the main tube. With this structure the vortex tube outputs primarily Hydrogen from one end and Carbon-based constituents from the other end. In some embodiments a second vortex tube receives the Carbon output of the first vortex tube to establish a water gas shift reactor, producing Hydrogen from the Carbon output of the first vortex tube.

摘要： A battery and an associated method are provided for generating power using an air cathode battery with a slurry anode. The method provides a battery with an air cathode separated from an anode current collector by an electrically insulating separator and an extrusion gap. The anode current collector extruder has a first plate with a plurality of slurry outlet perforations, and a sleeve having a first partition immediately adjacent to the extruder first plate, with a plurality of slurry inlet perforations. Active slurry is provided under pressure to an extruder inlet, and the extruder first plate slurry outlet perforations are selectively aligned with sleeve first partition slurry inlet perforations. Active slurry deposits are formed in the extrusion gap to mechanically charge the battery. In the discharge position, the sleeve moves so that the perforations no longer align, and slurry in the extruder is isolated from slurry in the extrusion gap.
