The medium-high temperature methanol electrolysis hydrogen production reactor comprises an end plate, an anode plate, an anode gas diffusion layer, a medium-high temperature membrane electrode, a cathode gas diffusion layer and a cathode plate, the medium-high temperature membrane electrode mainly comprises a medium-high temperature acidic electrolyte membrane, a double-catalyst-layer anode and a cathode; the double-catalyst-layer anode comprises an outer catalyst layer and an inner catalyst layer; the working temperature of the medium-high temperature methanol electrolysis hydrogen production reactor is 160-250 DEG C. When the reactor works, a methanol aqueous solution introduced into the anode side sequentially passes through the anode plate and the anode gas diffusion layer to reach the double-catalyst-layer anode, and after a certain potential is applied, the methanol aqueous solution enters the anode gas diffusion layer to reach the double-catalyst-layer anode. Methanol is subjected to an electrochemical
