Storage module of distributed flow battery

A storage module of a distributed flow battery, wherein an electrochemical reaction is processed with positive and negative electrolytes to generate and discharge direct current and further output said positive and negative electrolytes after said reaction and wherein said storage module comprises:

• two end plates, wherein one of said end plates has an input connector connecting with a negative electrolyte source and an output connector connecting back to said negative electrolyte source and the other one of said end plates has an input connector connecting with a positive electrolyte source and an output connector connecting back to said positive electrolyte source;
• two insulating frames of plastic material arranged between said end plates;
• two current collectors, arranged between said frames and wherein an end of each one of said current collectors has a graphite paper;
• two complex cast polar plates arranged between said current collectors and each comprising a graphite plate and a border plate integrally-molded on said respective graphite plate as a unipolar plate, wherein a surface of each said graphite plate has a plurality of electrolyte flow conduits and wherein, through said graphite paper, each said current collector contacts the other surface of said respective graphite plate at an opposite side having said electrolyte flow conduits so as to combine said current collector, said graphite plate, and said graphite paper;
• and wherein said border plate has a plurality of conduit branches and a plurality of manifold holes and said conduit branches of said border plate guide said positive and negative electrolytes to flow in and out said graphite plate;
• a positive electrode and a negative electrode, each electrode made of plasma-modified carbon felt and arranged between the complex cast polar plates;
• a membrane arranged between said electrodes and made of a membrane material of polysulfone (PSF) modified through atom transfer radical polymerization (ATRP);
• and
• three gaskets, wherein two of said gaskets sandwich and enclose one of said complex cast polar plates and the other one of said gaskets is arranged between the other one of said complex cast polar plates and an adjacent one of said current collectors.
