1. An electrochemical pump unit of mesh combined electrode connected to a power supply includes:
a mesh electrode, connected to a first polarity of the power supply, wherein the mesh electrode is configured so that when a first electrochemical reaction generates a first gas, said first gas can flow through screen meshes of said mesh electrode;
a second electrode, connected to a second polarity of the power supply, wherein the second electrode includes a plane electrode composed of a substrate layer and an electrode layer;
a superabsorbent material layer, located between said mesh electrode and said second electrode, wherein said superabsorbent material layer stores an electrolyte and wherein the second electrode is configured so that when a second electrochemical reaction generates a second gas, said second gas flows through inter fibrous small space/channels of said superabsorbent material layer and said screen meshes of the mesh electrode; and
an outer casing, wrapping said mesh electrode, said second electrode and said superabsorbent material layer, said outer casing includes a gas outlet, the first gas and the second gas are discharged from said gas outlet.
