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.

该小型企业创新研究第一阶段项目旨在研究一种方法，以大幅降低正在积极开发的燃料电池作为电动汽车电源的成本。具体来说，该计划将展示含有少量或不含贵金属的廉价催化剂作为质子交换膜燃料电池（PEMFC）中H2氧化催化剂的实际应用。该催化剂旨在取代目前在PEMFC中使用的昂贵的Pt阳极催化剂。第一阶段计划的目标是证明催化剂的短期稳定性，开发与这些催化剂一起使用的有效电极结构，并评估催化剂对燃料流中污染物的耐受性。该计划将最终在一个40平方厘米的活性面积PEMFC包含最有前途的催化剂连续运行至少200小时。开发廉价的催化剂来替代铂基质子交换膜燃料电池阳极催化剂将导致质子交换膜燃料电池的成本显着降低，提高质子交换膜燃料电池驱动的车辆与内燃机驱动的车辆的经济竞争力。
