Recommended Practice for Testing Performance of PEM Fuel Cell Stack Sub-system for Automotive Applications

2011-08-12
CURRENT
J2617_201108
This recommended practice is intended to serve as a procedure to verify the functional performance, design specifications or vendor claims of any PEM (Proton Exchange Membrane) type fuel cell stack sub-system for automotive applications. 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.

Gaseous Hydrogen and Fuel Cell Vehicle First and Second Responder Recommended Practice

2016-06-03
CURRENT
J2990/1_201606
Electric and alternative fueled vehicles present different hazards for first and second responders than conventional gasoline internal combustion engines. Hydrogen vehicles (H2V) including Fuel Cell Vehicles (FCVs) involved in incidents may present unique hazards associated with the fuel storage and high voltage systems. The electrical hazards associated with the high voltage systems of hybrid-electric vehicles and FCVs are already addressed in the parent document, SAE J2990. This Recommended Practice therefore addresses electric issues by reference to SAE J2990 and supplements SAE J2990 to address the potential consequences associated with hydrogen vehicle incidents and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred. Industry design standards and tools were studied and where appropriate, suggested for responsible organizations to implement.

Information Report on the Development of a Hydrogen Quality Guideline for Fuel Cell Vehicles

This Information Report provides interim background information and an interim specification of hydrogen fuel quality for commercial proton exchange membrane (PEM) fuel cell vehicles. This Report also provides background information on how this interim specification was developed by the Hydrogen Quality Task Force (HQTF) of the Interface Working Group (IWG) of the SAE Fuel Cell Standards Committee. The constituents and thresholds listed in Table 1 are based on a survey of the industry, the published literature and reflects current and draft analytical test methods. Some of the allowable constituent levels are higher than desired because a published detection method is not available for the desired threshold. Some of the allowable constituent levels may be lower than desired due to incomplete evaluations and/or an attempt to minimize testing costs (such as including methane in total hydrocarbons).

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.
