    • A self-spinning electro-spark linear cutting machine includes a main body having a working table, a power box and a control system, an emulsion box and at least one wire traveling device that operates the electrode wire in a high speed rotation, while making a linear movement. The wire traveling device includes a main shaft, a wire spool coaxially mounted on and rotable about the main shaft, and speed transformation gears driven by the main shaft and coupled for driving the wire spool to rotate coaxially in the same direction but at a different speed with the main shaft.

    • This invention relates to fabrication methods for catalyst coated membranes, including the steps of: exposing a micro-porous membrane to a catalyst dispersing solution to form a catalyst containing micro-porous membrane; exposing said catalyst containing micro-porous membrane to a resin dispersing solution to form a catalyst layer; and placing a proton exchange membrane between two of said catalyst layers with a laminating process to form the catalyst coated membrane. The fabrication methods of this invention provide filling process to uniformly fill the catalysts and resin throughout the pores of the micro-porous membranes in the catalyst layers. These micro-porous membranes are hydrophobic and easily discharge water when necessary. Therefore, membrane electrode assemblies with catalyst coated membranes fabricated using the methods of this invention are stable and perform well during fuel cell operation.
    • 本发明涉及催化剂涂覆膜的制造方法,包括以下步骤:将微孔膜暴露于催化剂分散溶液以形成含有微孔膜的催化剂; 将含有微孔膜的催化剂暴露于树脂分散溶液中以形成催化剂层; 以及在两个所述催化剂层之间放置质子交换膜,并进行层压工艺以形成催化剂涂覆的膜。 本发明的制造方法提供了填充方法,以在催化剂层中的微孔膜的整个孔中均匀填充催化剂和树脂。 这些微孔膜是疏水性的,并且在必要时容易排出水。 因此,使用本发明的方法制造的具有催化剂涂覆膜的膜电极组件在燃料电池操作期间是稳定的并且表现良好。
