The invention discloses a direct methanol fuel cell capable of realizing heat balance and material separation as well as a working method thereof. The direct methanol fuel cell is characterized in that methanol and a product are separately conveyed, a stable downstream transmission flow path is formed in the whole process of the fuel cell entirety from a moment that liquid-phase methanol flows through to a moment that carbon dioxide is discharged, the problems that methanol reaction is insufficient and methanol vapor concentration is nonuniform as methanol and carbon dioxide are mixed are solved, stable and efficient performance of a reaction at an anode side is better benefited, and cell efficiency is improved; extra heat produced in a fuel cell operation process is transmitted into a methanol evaporation region, and energy consumption is reduced while a fuel cell operating temperature is lowered; and a cell product carbon dioxide enters a pneumatic diaphragm pump under the action ofair pressure, a carbon di
