LOW-COST PEM HYDROGEN OXIDATION CATALYSTS

这个小企业创新研究第一阶段的项目是针对一种方法，以显著降低燃料电池的成本，燃料电池正在积极开发作为电动汽车的动力源。具体来说，该项目将展示在质子交换膜燃料电池（PEMFC）中，廉价催化剂（含贵金属很少或不含贵金属）作为h2氧化催化剂的实际应用。该催化剂旨在取代目前用于pemfc的昂贵的Pt阳极催化剂。第一阶段项目的目标是证明催化剂的短期稳定性，开发用于这些催化剂的有效电极结构，并评估催化剂对燃料流中污染物的耐受性。该项目最终将使含有最有前途催化剂的40平方厘米活性面积的PEMFC连续运行至少200小时。开发廉价的催化剂来取代基于pt的PEMFC阳极催化剂，将大大降低PEMFC的成本，提高PEMFC动力汽车与内燃机动力汽车的经济竞争力。

This Small Business Innovation Research Phase I project is directed at a method to significantly reduce the cost of fuel cells which are actively being developed as the power source for electric vehicles. Specifically, this program will demonstrate the practical application of inexpensive catalysts, containing little or no noble metal, as H2-oxidation catalysts in a proton-exchange membrane fuel cell (PEMFC). The catalysts are intended to replace the costly Pt anode catalysts, currently used in PEMFCs. Objectives of the Phase I program are to demonstrate short-term stability of the catalysts, develop efficient electrode structures for use with these catalysts, and evaluate the tolerance of the catalysts to contaminants in the fuel stream. The program will culminate in continuous operation of a 40-cm2 active area PEMFC containing the most promising catalyst for a minimum of 200 hours. The development of inexpensive catalyst to replace the Pt-based PEMFC anode catalysts would result in a significant reduction in PEMFC cost, increasing the economic competitiveness of PEMFC-powered vehicles with vehicles powered by internal-combustion engines.
