    摘要: An apparatus and a method for manufacturing electrical and optical materials by ink-jet printing of electronic ink(s) onto a flexible substrate are provided. The apparatus includes a flexible substrate, a first roll and a second roll, a printing head for depositing a electronic ink onto the substrate according to a predetermined pattern, and a drying station for drying an amount of deposited electronic ink. Each roll is reversibly configured for feed or takeup of the substrate. When dry, the deposited electronic ink forms one of an electronic material, an optical material, a display, and a fuel cell electrode. The apparatus may also include a second printing head configured for depositing a second electronic ink onto the substrate after the first ink has dried. The apparatus may be configured to rewind the substrate prior to deposition of the second ink, or to reverse the feed/takeup direction of the rolls.

    摘要: A fabrication method for catalyst coated membranes includes the steps of : exposing a micro-porous membrane to a catalyst dispersing solution to form a catalyst containing micro-porous membrane; exposing the catalyst containing micro-porous membrane to a resin dispersing solution to form a catalyst layer; and placing a proton exchange membrane between two of the catalyst layers with a laminating process to form the catalyst coated membrane. The fabrication method provides a filling process to uniformly fill the catalyst and resin throughout the pores of the micro-porous membranes in the catalyst layers. The micro-porous membranes are hydrophobic and easily discharge water when necessary. Therefore, membrane electrode assemblies with catalyst coated membranes fabricated using the method are stable and perform well during fuel cell operation.

    摘要: 燃料電池用触媒電極は固体高分子型燃料電池の発電効率を向上するために重要である。従来、炭素系拡散層基板または高分子電解質基板の表面に触媒を全面塗布する方法が使用されてきたが、本発明においては基板に二次元的または三次元的に微小点状(ドット)パターン触媒を固定することにより、単位表面積当たりの触媒担持量が相対的に低減しても却って当該触媒による発電される燃料電池の発電効率は増大することが発見できた。当該触媒を担持させる炭素構造等または高分子電解質等の基板は特に限定されていないし、二次元的または三次元的な微小点状(ドット)パターン触媒の作製方法は特に限定されない。
