Abstract: An electrochemical cell is presented. The cell includes a housing having an interior surface defining a volume, and an elongated separator disposed in the housing volume. The elongated separator defines an axis of the cell. The separator has an inner surface and an outer surface. The inner surface of the separator defines a first compartment. The outer surface of the separator and the interior surface of the housing define a second compartment having a volume. The cell further includes a conductive matrix disposed in at least a portion of the second compartment volume such that the conductive matrix occupies a gap between the outer surface of the separator and the interior surface of the housing. The gap in the second compartment extends in a direction substantially perpendicular to the axis of the cell.

Abstract: A combustor for a gas turbine system includes a combustor casing having an interior-establishing wall, and a chamber extending to the interior-establishing wall. In addition, the combustor includes an igniter assembly disposed within the chamber such that a tip of the igniter assembly is positioned radially outwardly from the interior-establishing wall. The igniter assembly includes a first electrode, a second electrode, and an insulator. In addition, the first electrode, the second electrode, and the insulator form a cavity, the second electrode forms an outlet passage extending from the cavity, a maximum cross-sectional area of the cavity is greater than a minimum cross-sectional area of the outlet passage, and the first electrode and the second electrode are configured to ionize gas within the cavity in response to an electrical current applied to the first electrode or to the second electrode.

Abstract: The present disclosure relates to gas turbine engine operation in which an igniter assembly is provided with an electrical energy input (e.g., an electrical waveform) that is configured to increase a likelihood of igniting a fuel-air mixture surrounding the igniter assembly. In certain embodiments, the igniter assembly is supplied with an augmented electrical waveform that may reduce a quantity of sparks generated by the igniter assembly before successful light-off (e.g., ignition) of the fuel-air mixture is achieved (e.g., as compared to a quantity of sparks generated to achieve ignition by an igniter assembly that receives an electrical energy input in the form of a conventional electrical waveform). Accordingly, the augmented electrical waveform may reduce wear (e.g., via oxidation) on electrodes of the igniter assembly, such as a primary electrode (e.g., a center electrode) and a secondary electrode (e.g., an outer shell electrode) disposed about the primary electrode.

The first electrode, the second electrode, and the insulator form a cavity, the second electrode forms an outlet passage extending from the cavity, a maximum cross-sectional area of the cavity is greater than a cross-sectional area of the outlet passage, and the cross-sectional area of the outlet passage is substantially constant along a longitudinal extent of the outlet passage. In addition, the first electrode and the second electrode are configured to ionize gas within the cavity in response to an electrical current applied to the first electrode or to the second electrode.

Abstract: A cathode composition is presented. The cathode composition includes an alkali metal halide and an electroactive metal. The electroactive metal includes a first population of particles that is present in a range at least about 50 weight percent of a total weight of the electroactive metal. A specific surface area of the first population of particles is lower than 0.2 m2/g. An electrochemical cell and an energy storage system including the cathode composition are also presented.
