    摘要: A gas diffusion layer, a manufacturing apparatus and a manufacturing method thereof are provided. The gas diffusion layer having different hydrophilic/hydrophobic structure and channel therein can be manufactured quickly and easily by using a coating mask. The gas diffusion layer is used in various fuel cells to enhance the ability of water management and to solve the problem of flooding at the cathode, the problem of water deficit at the anode, and the problem of gas transfer. The gas diffusion layer includes a gas diffusion medium having a first property and a micro porous layer having a second property. The micro porous layer is formed on one surface of the gas diffusion medium. The micro porous layer has a plurality of channel layers penetrating the gas diffusion medium. One of the first property and the second property is hydrophilic, and the other is hydrophobic.

    摘要: A method for manufacturing metal nano particles having a hollow structure is provided. First, a suitable reducing agent is added into a first metal salt solution, and first metal ions are reduced to form first metal nano particles. Next, after the reducing agent is decomposed, a second metal salt solution with a higher reduction potential than that of the first metal is added. Then, the first metal particles are oxidized to form first metal ions when the second metal ions are reduced on the surface of the first metal by electrochemical oxidation reduction reaction, and thus, second metal nano particles having a hollow structure and a larger surface area are obtained. The method is simple and the metal nano particles with uniform particle size are obtained by this method.

    摘要: An electrode structure of a fuel cell for power generation comprises an anodic structure, a cathodic structure, and an ionic exchange membrane disposed between the anodic and cathodic structures. The anodic and cathodic structures respectively are formed by multi-layer structures, to reduce the fuel crossover from the anodic structure to the cathodic structure, to reduce the catalysts applied amount, and to increase an output electrical energy of the fuel cell. The multi-layer structure of the anodic structure comprises a thin platinum alloy black layer, a Pt alloy layer disposed on the carbon material, and a substrate.
