    摘要: A cathode catalyst for a fuel cell is inexpensive and has high durability against methanol. A method of manufacturing and fixing the cathode catalyst, and a fuel cell including it, are disclosed. The cathode catalyst includes a compound selected from the group consisting of PdSn, PdAu, PdCo, PdWO3, and mixtures thereof. The present invention can provide a non-platinum-based cathode catalyst as a substitute for a platinum catalyst, the cathode catalyst having a low cost and improved catalyst activity, thereby contributing to popular use of a fuel cell. In addition, since the cathode catalyst of the present invention has high durability against methanol and can thereby be used with a fuel in a high concentration, it can increase the energy density of a direct methanol fuel cell (DMFC).

    摘要: A fuel cell includes a substrate having a pair of grooves, an electrolyte membrane lying on the substrate so as to define a pair of flow channels, and catalyst-bearing current collector layer sections disposed on the inner wall of the grooves or the inside surface of the electrolyte membrane defining the channels. A fuel liquid flows through the first channel to undergo anodic reaction, an oxidant liquid in the form of an aqueous hydrogen peroxide solution flows through the second channel to undergo cathodic reaction, and hydrogen ions traverse the electrolyte membrane.
