BATTERY CELL AND BATTERY STACK

A stack of rectangular planar electrochemical cells (200), each cell (200) comprising at least one first fluid intermediate port (230, 235) disposed within or between one or more activated battery chemistry regions (210) along the middle of the length of the cell and in fluid communication with a first fluid volume of the cell (200). The first fluid intermediate ports (230, 235) of the respective battery cells (200) are aligned to form at least one first fluid intermediate passage extending in the stacking direction. The stack is configured such that, in each first fluid volume, a first fluid flow path (405, 410) extends through one or more activated cell chemistry regions (210) between the at least one first fluid intermediate port (230, 235) and each respective opposing cell end. 一种矩形平面电化学电池单元(200)堆叠，每个电池单元(200)包括至少一个第一流体中间端口(230，235)，所述第一流体中间端口(230，235)沿所述电池单元的长度的中部设置在一个或多个活化电池化学区域(210)内或之间，并且与电池单元(200)的第一流体体积流体连通。各相应的电池单元(200)的第一流体中间端口(230，235)对齐，以形成沿堆叠方向延伸的至少一个第一流体中间通路。所述堆叠被配置成使得在每个第一流体体积中，第一流体流动路径(405，4
