This Small Business Innovation Research (SBIR) Phase I project addresses the development of Sensors wherein the adsorption of trace sulfur contaminants in natural gas will be monitored at the surface of the sensor. The system will be optimized to measure total sulfur species such as dimethyl sulfide (DMS) in natural gas, to aide in the control of desulfurization systems used in high temperature fuel cells.While natural gas is a readily available fuel to generate electricity with fuel cells, the traces of sulfur compounds must be removed first to prevent electrode poisoning and fouling. The proposed mixed metal oxide sulfur sensor will improve the reliability and service life for high temperature solid oxide and molten carbonate fuel cells used for stationary power. The unique features for selectively adsorbing/desorbing interfering gases make this sensor applicable to a wide variety of other sensing needs. The metal oxide dual sensors may be suitable for operating environments where there are wide changes in humidity, temperature and mechanical stress.

小型企业创新研究(SBIR)第一阶段项目致力于传感器的开发，其中将在传感器的表面监测天然气中微量硫污染物的吸附情况。该系统将进行优化，以测量天然气中的总硫物种，如二甲基硫(DMS)，以帮助控制高温燃料电池使用的脱硫系统。虽然天然气是一种随时可以用来用燃料电池发电的燃料，但必须首先去除微量的硫化物，以防止电极中毒和结垢。提出的混合金属氧化物硫传感器将提高用于固定电源的高温固体氧化物和熔融碳酸盐燃料电池的可靠性和使用寿命。选择性吸附/解吸干扰气体的独特功能使该传感器适用于各种其他传感需求。金属氧化物双传感器可能适用于湿度、温度和机械应力变化较大的工作环境。
