An electrocatalyst for ethanol oxidization includes an elemental mixture containing platinum and ruthenium and at least one element, wherein the foregoing at least one element is selected from the group of tungsten, tin, molybdenum, copper, gold, manganese, and vanadium.

The invention discloses a direct methanol fuel cell capable of realizing pure methanol supply. The fuel cell comprises a cell shell, and a pervaporation membrane which is fixed on the cell shell and divides an inner chamber into a methanol fuel chamber and a steam chamber, wherein an anode flow field plate, a membrane electrode and a cathode flow field plate are sequentially arranged above the steam chamber from bottom to top in a stacking manner; a hollow cover plate covering a cathode collector plate is arranged at an open end of the cell shell in an insulation manner; a hydrophilic porous plate with hydrophily is arranged between the anode flow field plate and the anode side of the membrane electrode; a hydrophobic porous plate with hydrophobicity is arranged between the cathode side of the membrane electrode and the cathode flow field plate. According to the invention, continuous vaporization methanol supply is guaranteed, methanol crossover is restrained while cathode water is promoted to be reversely supplemented to the anode to participate in reaction, on the premise of guaranteeing output performance of the cell, the energy density of the cell is increased effectively, high-concentration methanol supply even pure methanol supply of the cell is realized and the service life of the cell is prolonged greatly.
