Abstract
According to one embodiment, a direct-methanol fuel cell includes an anode which includes a current collector and a first catalytic layer formed on the current collector and into which an aqueous methanol solution is introduced, a cathode which includes a current collector and a second catalytic layer formed on the current collector and into which an oxidizer is introduced and an electrolyte membrane interposed between the anode and the cathode. The second catalytic layer includes a catalyst, a perfluoroalkylsulfonic acid polymer, and a ternary metal-containing copolymer. The ternary metal-containing copolymer includes a first vinyl monomer containing an organic metal complex of Pt, a second vinyl monomer containing an organic metal complex of M1, where M1 is a metal selected from Sn, Zn, Ni, Fe, Co, Al and Cu and a third vinyl monomer containing an organic metal complex in which M2 is ionically bonded, where M2 is Eu or La.
