摘要： Provided is a transition metal-carbon nanofiber catalyst for a fuel cell using a nanofiber including only a low cost transition metal. More particularly, the transition metal-including carbon nanofiber catalyst is prepared by preparing a nanofiber from electrospinning of a solution containing a transition metal and a polymer precursor, followed by oxidative stabilization and carbonization. As a result, catalyst performance may be improved through effective modification of the functional groups on the nanofiber surface. The catalyst may be used as an electrode as it is since the size and thickness may be controlled effectively. Further, the catalyst may be subjected to fine grinding by ball milling, ultrasonic pulverization, etc. for use in other applications. The catalyst may be produced in large scale through relatively simple process of electrospinning and heat treatment processes without using expensive precious metal catalyst precursors such as platinum or reducing agents. In particular, with electrode activity and durability comparable to those of a platinum catalyst for oxygen reduction reaction in an alkaline medium, it is useful as an oxygen reduction catalyst for use in an alkaline fuel cell with improved cost competitiveness.
摘要翻译：本发明提供一种使用仅含有低成本的过渡金属的纳米纤维的燃料电池用过渡金属 - 碳纳米纤维催化剂。更具体地说，含过渡金属的碳纳米纤维催化剂是通过从含有过渡金属和聚合物前体的溶液静电纺丝制备纳米纤维，然后进行氧化稳定化和碳化来制备的。结果，可以通过有效修饰纳米纤维表面上的官能团来改善催化剂性能。由于可以有效地控制尺寸和厚度，因此可以将催化剂用作电极。此外，可以通过球磨，超声波粉碎等对催化剂进行精细研磨，以用于其它应用。催化剂可以通过相对简单的静电纺丝和热处理方法的工艺大规模生产，而不使用昂贵的贵金属催化剂前体如铂或还原剂。特别地，与碱性介质中的氧还原反应的铂催化剂相比，电极活性和耐久性相当，作为用于具有提高的成本竞争力的碱性燃料电池中的氧还原催化剂是有用的。

摘要： Provided are a method for preparing an electrode for a fuel cell and a method for preparing a membrane-electrode assembly for a fuel cell containing the same. The electrode for the fuel cell can be prepared by polarizing some of the upper parts of a porous conductive film and introducing a catalyst layer on the porous conductive film where some of the upper part is modified. Accordingly, a first catalyst can be uniformly spread on the polarized portion of the porous conductive film. As a result, the effective surface area of the catalyst is increased, so the catalyst amount used can be reduced. Additionally, even if density of the porous conductive film is increased, the catalyst can be easily introduced inside the porous conductive film.
