摘要： A stack of rectangular, planar electrochemical cell units (200), each cell unit (200) comprising at least one first fluid mid-port (230, 235) that is disposed midway along its length within or between one or more active cell chemistry regions (210) and is in fluid communication with a first fluid volume of the cell unit (200). The first fluid mid-ports (230, 235) of the respective cell units (200) align to form at least one first fluid mid-passageway extending in the stack direction. The stack is configured such that, in each first fluid volume, first fluid flow paths (405, 410) extend across the one or more active cell chemistry regions (210) between the at least one first fluid mid-port (230, 235) and each respective opposed cell end.

摘要： An alignment dowel comprises a body extending along a longitudinal axis, the body comprising a plurality of resilient vanes that extend generally perpendicular to the longitudinal axis, and an actuator portion. The stack has openings of a predetermined diameter. The vanes are arranged around the longitudinal axis so as to extend along the axis and project radially outwards to define an outer diameter of the body. The actuator portion is operable to move the vanes between a collapsed configuration in which the outer diameter is smaller than the predetermined diameter, and an expanded configuration in which the outer diameter of the body is greater than in the collapsed configuration. A stack assembly jig, comprises a tool base on which a stack of components can be positioned. The tool base has guide holes that are no smaller than the predetermined diameter and are positioned to correspond to the position of the openings in the stack. A base plate carries an array of alignment dowels arranged to correspond to the positions of the guide holes. The base plate is moveable relative to the tool base such that the alignment dowels can project through the guide holes and into the component openings. The actuators are operable to align the components in the stack. A method for aligning components of a cell stack using an alignment dowel, comprises arranging cells adjacent one another in a stack, wherein the cells have internal alignment features, wherein each alignment feature includes an engaging surface with which the alignment dowel is configured to engage and disengage when located within said alignment feature; and locating the alignment dowel in the alignment features in the collapsed configuration and operating the actuator to move the alignment dowel to the expanded configuration to align the cells.
