The invention discloses an assembly of a membrane electrode and a current collecting board used for an electrochemical cell, the assembly comprising a membrane layer, a gas diffusion layer on the one side and a layer of porous current collecting board on the one side which are stacked in sequence and wherein the gas diffusion layer on the one side is located between the porous current collecting board on the one side and the membrane. The area surrounding the periphery of the gas diffusion layer on the one side is filled with sealing material which is cured subsequently. The invention further discloses an electrochemical cell module comprising at least one electrochemical single cell which includes an end plate with gas channels, an assembly therefor, and an end plate with gas channels on the other side which are stacked in sequence. When compared with the prior art, this assembly provides a simpler structure and assembly process, thereby decreasing production cost when used on a large scale. Meanwhile, it also improves the effective available area of the membrane electrode. This assembly is also suitable for use in the production of fuel cells, electrolytic cells, regenerative fuel cells and electrochemical oxygen generators.
