21、bing a common fuel to be used by proton exchange membrane (PEM) fuel cell applications for stationary appliances in the near term.A large number of fuel cells are presently commercialized as power sources for stationary applications, such as distributed, supplementary, and back-up power generation a
22、nd as stationary heat and power cogeneration systems. Most stationary fuel cells are equipped with a fuel processing system which converts fossil fuel to hydrogen-rich fuel composed primarily of hydrogen and carbon dioxide. Some of the stationary fuel cells use hydrogen fuel of high purity supplied
23、through high pressure tanks or pipeline from a distant hydrogen production plant.The purpose of this part of ISO 14687 is to establish an international standard of quality characteristics of hydrogen fuel for stationary fuel cells.Types of fuel cells other than proton exchange membrane fuel cells (P
24、EMFC), such as phosphoric acid fuel cell (PAFC), molten carbonate fuel cells (MCFC) and solid oxide fuel cells (SOFC), may require similar standards in future. Thus, it is anticipated that in the future PAFC, MCFC and SOFC hydrogen fuel quality requirements will be added as amendments to this part o
25、f ISO 14687.This part of ISO 14687 is intended to consolidate the hydrogen fuel product specification needs anticipated by PEM fuel cell manufacturers and hydrogen fuel suppliers as both industries proceed toward achieving wide-spread commercialization. Monitoring hydrogen fuel quality is necessary
26、because specific impurities will adversely affect the fuel cell power system. In addition, there may be performance implications in the fuel cell power system if certain non-hydrogen constituent levels are not controlled. Methods to monitor the hydrogen fuel quality that is delivered to these statio
27、nary appliances are addressed.This part of ISO 14687 specifies one grade of hydrogen, Type I, grade E, with three categories for different target applications. Quality verification should be determined at the inlet point of a PEM fuel cell power system.Since PEM fuel cell applications for stationary
28、 appliances and related technologies are developing rapidly, this part of ISO 14687 will be revised according to technological progress as necessary. Additionally, some of the impurity limits are dictated by current analytical capabilities, which are also in the process of development. Technical Com
29、mittee ISO/TC 197, Hydrogen technologies, will monitor this technology trend. It is also noted that this part of ISO 14687 has been prepared to assist in the development of PEM fuel cell applications for stationary appliances and related technologies.Further research and development efforts should f
30、ocus on, but not be limited to: PEM fuel cell catalyst and fuel cell tolerance to hydrogen fuel impurities; Effects/mechanisms of impurities on fuel cell power systems and components; Impurity detection and measurement techniques for laboratory, production, and in-field operations; and, Stationary f
