The 5kW integrated system has been fully assembled and successful checks were made of most microprocessor-controlled operational features. Long-term testing will be deferred until the stack is rebuilt. A PURPA-derived definition of qualified cogenerator has been supplied by A.D. Little, Inc. Preliminary considerations are presented for the designs of the 25 kW stack and the 50 kW methanol fuel processor. Initial results are given for overall system analysis of a 50kW system under pressurized operation and also under part-load operation at normal pressure. A general discussion of waste heat utilization is also provided. Progress in several areas of stack componentry is reported, including bipolar plate production, acid management, Pt catalyst recrystallization and bipolar plate resistance measurement technique. Methanol steam reforming catalyst test results are reviewed in preparation for making a choice of design catalyst for the 50 kW system.

This document has been declared "Stabilized" and willno longer be subjected to periodic reviews for currency. Users areresponsible for verifying references and continued suitability ortechnical requirements. New technology may exist.This recommended practice is intended to serve as a designverification 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 thefuel processor subsystem (FPS) of a fuel cell system (FCS) areprovided. Fuel processor subsystems (FPS) include all componentsrequired in the conversion of input fuel and oxidizer into ahydrogen-rich product gas stream suitable for use in fuel cells.Performance of the fuel processor subsystem includes evaluatingsystem energy inputs and useful outputs to determine fuelconversion efficiency and where applicable the overall thermaleffectiveness. Each of these performance characterizations will bedetermined to an uncertainty of less than ±?2% of the value. Themethod allows for the evaluation of fuel processor subsystems fortwo general cases. ???Compare fuel processors with differentdesigns (e.g., catalytic partial oxidation reforming, autothermalreforming or steam reforming) on a common basis where no specificfuel cell system design has been identified. 2.)?Assess theperformance of a specific fuel processor in the context of aspecific fuel cell system design. This document applies to all fuelprocessor subsystems for transportation applications regardless offuel processor type, fuel cell type, electrical power output,thermal output, or system application (propulsion or auxiliarypower unit (APU)). For example, the fuel processor subsystemsassociated with proton exchange, molten carbonate and solid oxidefuel cells can differ due to the requirements of the fuel cellsthemselves.Performance of the fuel processor subsystem, and preprocessor ifapplicable, is evaluated. A stand alone fuel processor"system" or even the primary reactor (e.g., autothermal,partial oxidation or steam reforming reactor) of a fuel processorsubsystem that would normally be integrated into a fuel cell systemcan be evaluated. The fuel processor together with the preprocessor(if required) converts the fuel (gasoline or other liquidhydrocarbon) to a reformate gas consisting largely of H2, CO, CO2,H2O and N2 (if air is used). After the fuel processor subsystem,reformate gas typically contains only trace levels of carbonbearing components higher than C1. The FPS would be evaluated in atest facility that is designed to evaluate a stand-alone componentrather than a portion of the reformer such as a specific catalystor a particular vessel design.Any fuel(s) mutually agreed to by the test parties can be usedsuch as 1) straight run gasoline (EPA Fuel- CARB reformulatedgasoline Tier II, 30 ppm sulfur), or 2) methanol or 3) hydrocarbonfuel such as isooctane, naptha, diesel, liquefied natural gas (LNG)or LPG (propane), etc.The procedures provide a point-in-time evaluation of theperformance of the fuel processor subsystem. Steady state andtransient (start-up and load-following) performance are included.Methods and procedures for conducting and reporting fuel processortesting, including instrumentation to be used, testing techniques,and methods for calculating and reporting results are provided. Theboundary limits for fuel and oxidant input, secondary energy inputand net energy output are defined. Procedures for measuringtemperature, pressure, input fuel flow and composition, electricalpower and thermal output at the boundaries are provided.Procedures for determination of the FPS performance measuressuch as fuel processor efficiency and cold gas efficiency at arated load or any other steady state condition are provided.Methods to correct results from the test conditions to referenceconditions are provided.

Fuel Cells: Technologies for Fuel Processing provides an overview of the most important aspects of fuel reforming to the generally interested reader, researcher, technologist, teacher, student, or engineer. The topics covered include all aspects of fuel reforming: fundamental chemistry, different modes of reforming, catalysts, catalyst deactivation, fuel desulfurization, reaction engineering, novel reforming concepts, thermodynamics, heat and mass transfer issues, system design, and recent research and development. While no attempt is made to describe the fuel cell itself, there is sufficient description of the fuel cell to show how it affects the fuel reformer. By focusing on the fundamentals, this book aims to be a source of information now and in the future. By avoiding time-sensitive information/analysis (e.g., economics) it serves as a single source of information for scientists and engineers in fuel processing technology. The material is presented in such a way that this book will serve as a reference for graduate level courses, fuel cell developers, and fuel cell researchers. Chapters written by experts in each area Extensive bibliography supporting each chapter Detailed index Up-to-date diagrams and full colour illustrations

The fields covered by the hydrogen energy topic have grown rapidly, and now it has become clearly multidisciplinary. In addition to production, hydrogen purification and especially storage are key challenges that could limit the use of hydrogen fuel. In this book, the purification of hydrogen with membrane technology and its storage in "solid" form using new hydrides and carbon materials are addressed. Other novelties of this volume include the power conditioning of water electrolyzers, the integration in the electric grid of renewable hydrogen systems and the future role of microreactors and micro-process engineering in hydrogen technology as well as the potential of computational fluid dynamics to hydrogen equipment design and the assessment of safety issues. Finally, and being aware that transportation will likely constitute the first commercial application of hydrogen fuel, two chapters are devoted to the recent advances in hydrogen fuel cells and hydrogen-fueled internal combustion engines for transport vehicles. Hydrogen from water and biomass considered Holistic approach to the topic of renewable hydrogen production Power conditioning of water electrolyzers and integration of renewable hydrogen energy systems considered Subjects not included in previous books on hydrogen energy Micro process technology considered Subject not included in previous books on hydrogen energy Applications of CFD considered Subject not included in previous books on hydrogen energy Fundamental aspects will not be discussed in detail consciously as they are suitably addressed in previous books Emphasis on technological advancements Chapters written by recognized experts Up-to date approach to the subjects and relevant bibliographic references
