SCAQMD Method 301-91 Identification of Particles by Microscopy 3. DEFINITIONS Hydrogen fuel as defined in this S
26、tandard consists of hydrogen gas and trace impurities. The impurities consist of both inert and reactive contaminants. Inert contaminants, generally, do not permanently affect the performance of a fuel cell. Inert contaminants may affect the performance of the fuel cell system including hydrogen sto
27、rage tanks, regulators etc. Reactive contaminant effects can be reversible, partially reversible or irreversible in their impact on the performance and/or life of the fuel cell. Additional related definitions are noted in Appendix A. 3.1 CONSTITUENT A component compound or element found within a hyd
28、rogen fuel mixture 3.2 CONTAMINANT An impurity that adversely affects the components within the fuel cell system or the hydrogen storage system by reacting with its components or that reduces the energy content of the fuel through dilution. An adverse effect can be reversible or irreversible. 3.3 DI
29、LUENT An impurity that reduces the concentration of hydrogen, and may be a contaminant or non-reactive in nature. 3.4 FUEL CELL SYSTEM A power system producing electrical energy which typically includes the fuel cell stack, equipment for air processing, fuel processing, thermal management, water man
30、agement, and the balance of plant. 3.5 HYDROGEN FUEL INDEX The hydrogen fuel index is the value obtained when the amount of aggregate impurities, as, expressed as percent (Pmole/Pmole), is subtracted from 100%. 3.6 INERT GAS Non-reactive gases such as argon, helium, krypton, neon, radon, and xenon.
31、3.7 IMPURITY A non-hydrogen constituent in hydrogen fuel. SAE INTERNATIONAL J2719 NOV2015 Page 6 of 14 3.8 IMPURITY LIMIT The concentration limit of each specific impurity analyzed in a hydrogen fuel. Impurity limits are designated in micromoles per mole of fuel (mol/mol) with the exception of parti
32、culates, which are designated by mass concentrations (milligrams per kilogram of hydrogen fuel). 3.9 PARTICULATE A solid or aerosol particle that may be entrained or introduced in the production, storage, delivery, or use of hydrogen fuel. Particulates are specified by mass concentration (milligrams
33、 per kilogram of fuel). 3.10 SUBLIMATE An impurity that may undergo a phase-change from solid to gaseous state in the production, delivery, storage or use, of hydrogen fuel. 3.11 TRACER An easily detected inert substance introduced into a fuel stream. 3.12 THRESHOLD LIMITS The concentration threshol
34、d level of each specific impurity analyzed in a hydrogen fuel. Thresholds are designated in micromoles per mole of fuel (mol/mol) with the exception of particulates, which are designated by size (in micrometers) and mass concentrations (milligrams per kilogram of hydrogen fuel. 4. HYDROGEN QUALITY S
35、PECIFICATION Development of this standard is based upon consideration of technical presentations given to and discussions with the IWG by industry, universities and other organizations, such as NEDO/JARI, DOE national laboratories, CaFCP, U.S. Fuel Cell Council (USFCC) and ASTM International. The hy
36、drogen quality specification resulting from consensus agreement between the various stakeholders is shown in Table 1, Hydrogen Quality Specification. Particulate concentration should be minimized to avoid contamination, clogging, and erosion of fuel system components. The fuel should be processed wi
37、th a filter rated at 10 micron nominal (i.e., 98% efficiency) particle size. 4.1 Threshold Limits The limits in Table 1 were derived by consensus by national and academic laboratories whose work was sponsored by the Japanese government through NEDO and the US government through DoE EERE. Appendix B
38、gives guidance on the rationale for selecting the compounds listed in the table. Appendix C lists the papers that supplied the test data supporting the various limits. The analytical methods listed in Table 1 are not intended for use as process control or field verification methods. They are intende
39、d for uses a resource in for the generation of process equipment calibration gases, field sampling methodology validation and as a method for resolving third party disputes. It is expected that process control and field verification methodology will evolve under the leadership of the fuel providers
40、and applicable federal and state agencies. Some constituents are listed in terms of family of compounds associated with the total accepted threshold limit per family, as well as example constituents in the particular family. The list is not intended to be totally inclusive. Although there may be mor
41、e (or less) speciation per each family, the data presented here reflect the current knowledge of constituents of concern. SAE INTERNATIONAL J2719 NOV2015 Page 7 of 14 The analytical methods and limits of detection contained in Table 1 are based on available ASTM Standards or upon ASTM Standards docu
42、mented as under development. Although for many constituents the public analytic techniques satisfy the requirements for testing hydrogen fuel used in demonstration projects, hydrogen sold commercially is likely to require lower contaminant detection than has been validated for these methods. The lim
43、its for constituents in Table 1 are the same as the detection limits in some cases. As a result these constituents will require methods with detection limits validated one or more orders of magnitude below the listed limits. Subsequent revisions of this standard may include additional constituents a
44、s supported by data. In addition, the constituent list addresses a wide range of constituents not all of which are expected to be present in every source of hydrogen. Requirements for filtering of particulate matter from the fuel stream are contained in fueling dispenser construction documents (e.g.
45、, CSA HGV 4.1. ISO 20100). Total hydrocarbons on a C1 basis is a methodology where total carbon is calculated and all of the hydrocarbons are assumed to have only a single carbon atom. Therefore, if the total carbon on a C1 basis calculates out to 1 mole hydrocarbon/mole of hydrogen and the hydrocar
46、bon was methane (CH4), there would be 1 mole of methane/mole of hydrogen. However, if the hydrocarbon were benzene (C6H6), 1 mole hydrocarbon/mole of hydrogen calculates out to 0.17 mole benzene/mole of hydrogen. Alternative commercially accepted analytical methods may be used if they are suitable t
47、o detect the impurity at or below the limit and the seller and the buyer (or the Authority Having Jurisdiction) concur. These requirements are a reflection of the current level of published knowledge on this topic. Limits will be revised as additional information on long-term impacts and mechanisms
48、of fuel cell impact are explored and understood. Test methodology will be updated as it becomes available from ASTM. 4.2 Sampling It is recommended that samples taken to determine the gaseous components in Table 1 conform to ASTM D7606-11. It is also recommended that samples taken to determine the p
49、articulates in Table 1 conform to ASTM D7650-10. Alternative commercially accepted sampling methods may be used if they are suitable for the task and the seller and buyer (or the Authority Having Jurisdiction) concur.
