1. An integrated flow battery stack and heat exchange module comprising:
a battery stack comprising a plurality of cells coupled electrically and thermally to one another, each of the plurality of cells comprising two electrodes separated by a membrane, wherein a negative electrolyte and a positive electrolyte are circulated through each of the plurality of cells to enable redox reaction at each of the two electrodes;
a current collector plate at each end of the battery stack, each current collector plate electrically and thermally coupled to said battery stack, and each current collector plate electrically coupled to an external circuit element, wherein the current collector plate is configured to collect cumulative current generated by the battery stack and to supply or remove heat from the battery stack;
a heat exchange plate thermally coupled to at least one current collector plate, said heat exchange plate further coupled to a temperature regulator, wherein said temperature regulator is configured to control the temperature of the heat exchange plate, and
wherein said heat exchange plate exchanges heat with the battery stack through the current collector plate to enable temperature of the battery stack to be within a predetermined optimal range of temperature.
