Abstract:
1. A frame for a cell of a redox flow battery, said frame including first, second, third and fourth inner sides enclosing a generally rectangular opening for an electrode, said frame comprising: a liquid inflow channel for delivering electrolyte to one end of a first distribution channel formed along said first inner side of said frame, a liquid outflow channel for removing electrolyte from a second distribution channel formed along said second inner side of said frame, said second inner side being opposite said first inner side, such that electrolyte delivered to said first distribution channel from said inflow channel will flow from said first distribution channel across said opening and through an electrode located therein to said second distribution channel and out through said liquid outflow channel, and a first rim providing said third inner side of said frame and including a plurality of first flow blocker means which extend along an entire height of said first rim and project into said opening to block electrolyte from flowing from said first distribution channel to said second distribution channel between said first rim and an adjacent peripheral surface of an electrode when positioned in said opening, one of said plurality of flow blocker means being located at an end of said first rim adjacent said one end of said first distribution channel where said inflow channel delivers electrolyte.
