CURRENT
J2615_201110
This recommended practice is intended to provide a framework for performance testing of fuel cell systems (FCS’s) designed for automotive applications with direct current (DC) output. The procedures described allow for measurement of performance relative to claims by manufacturers of such systems with regard to the following performance criteria. — Power — Efficiency — Transient Response — Start and Stop Performance — Physical Description — Environmental Limits — Operational Requirements — Integration Since this recommended practice is based on the principal of performance measurement relative to a claim, the testing parties should take care to include any qualifying or unique circumstances leading to the test results reported in order to achieve full disclosure. For example, efficiency as defined in section 3.1.9 allows for the inclusion of thermal output benefit.

In this document, definitions, specifications, and methods for the functional performance characterization of the fuel cell stack sub-system are provided. The functional performance characterization includes evaluating electrical outputs and controlling fluid inputs and outputs based on the test boundary defined in this document. In this document, a fuel cell stack sub-system is defined to include the following: Fuel cell stack(s) – An assembly of membrane electrode assemblies (MEA), current collectors, separator plates, cooling plates, manifolds, and a supporting structure. Connections for conducting fuels, oxidants, cooling media, inert gases and exhausts. Electrical connections for the power delivered by the stack sub-system.

Testing Performance of the Fuel Processor Subsystem of an Automotive Fuel Cell System

2011-08-12
CURRENT
J2616_201108
This recommended practice is intended to serve as a design verification procedure and not a product qualification procedure. It may be used to verify design specifications or vendor claims. Test procedures, methods and definitions for the performance of the fuel processor subsystem (FPS) of a fuel cell system (FCS) are provided. Fuel processor subsystems (FPS) include all components required in the conversion of input fuel and oxidizer into a hydrogen-rich product gas stream suitable for use in fuel cells. Performance of the fuel processor subsystem includes evaluating system energy inputs and useful outputs to determine fuel conversion efficiency and where applicable the overall thermal effectiveness. Each of these performance characterizations will be determined to an uncertainty of less than ± 2% of the value. The method allows for the evaluation of fuel processor subsystems for two general cases.

Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles*

2010-03-16
HISTORICAL
J2601_201003
SAE TIR J2601 establishes safety limits and performance requirements for gaseous hydrogen fuel dispensers. The criteria include maximum fuel temperature at the dispenser nozzle, the maximum fuel flow rate, the maximum rate of pressure increase and other performance criteria based on the cooling capability of the station’s dispenser. This document establishes fueling guidelines for “non-communication fueling” in the absence of vehicle communication and guidelines for “communication fueling” when specified information is transmitted from the vehicle and verified at the dispenser. The process by which fueling is optimized using vehicle-transmitted information is specified. This document provides details of the communication data transmission protocol. The mechanical connector geometry is not covered in this document. SAE J2600 defines the connector requirements for fueling vehicles operating with a nominal working pressure of 35 MPa.

J2572_200810
This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing.
