Introduction

"Fixed Proton Exchange Membrane Fuel Cell Power Generation System (Independent Type) Performance Test Method" is the National "Tenth Five-Year" Important Science and Technology Project Technical standards research project "new energy and renewable energy key technical standards --- proton exchange membrane fuel cell, solar hot water system, Grid-connected photovoltaic power generation and wind turbine "to study the development, combined with China's" 863 "plan fuel cell electric vehicle major project proton to pay for membrane fuel cell technology, one of the series of national standards. This section provides a fixed proton exchange membrane fuel cell power generation system (independent) (Hereinafter referred to as power generation system) operational performance and its impact on the environment test methods.

Fuel cells are not only suitable for the construction of stationary power plants to provide community and household electricity sources, but more importantly, to provide power for electric vehicles and micro-fuel cells for use in a variety of communications equipment, laptops and handheld computers. And fuel Battery technology is from these aspects of research and development to industrial change, fuel cells in fixed power stations, transport and portable power supply, etc.

Aspects of commercialization are coming. Some technologies related to fuel cells will also be commercialized in the next 5 to 10 years. Some new technologies, New materials and new components will also be rapidly developed on the basis of internationalization of the market. It is foreseeable that fuel cell technology will be sustained and rapid development of.

During the "Ninth Five-Year Plan" and "Tenth Five-Year Plan" period, all the PEMFCs and their related technologies were listed as major projects in the country Scientific and technological breakthroughs include "863" fuel cell vehicles major projects, and has achieved initial results. At present, China's PEMFC technology to colleges and universities and research institutes for technical support to several major high-tech enterprises as a leader, has formed in Dalian, Shanghai, Beijing and Wuhan, etc.

The main research and development base. Some of them have obtained patented technology with independent intellectual property rights and are actively promoting China's fuel cell technology Industrialization and commercialization.

Early development of standards for the promotion of this new technology with unlimited potential for development - the commercialization and commercialization of fuel cells is very heavy need. International Electrotechnical Commission (IEC ) established IEC/T C105 to be responsible for fuel cell professional standards work in recent years, very frequent activities Many, has released a number of international standards. China fuel cell technology in tackling the issue of tackling and tracking international standards at the same time, according to our country the actual arrangements for the development of relevant key technical standards, designed to reflect the standard early intervention in the industrialization of scientific and technological achievements, with the international practice Read Currently completed standard projects are.

1 Scope

1.1 This Guidance Document specifies the operational performance of a fixed proton exchange membrane fuel cell power generation system (hereinafter referred to as power generation system) Aspects and its impact on the environment test methods.

1.2 The test of the contents of the guidance of technical documents include.

Output power under specified operating conditions;

Power generation efficiency and heat utilization efficiency under specified operating conditions;

Environmental characteristics under specified operating conditions. eg, emissions, noise, etc .;

This technical document does not cover Electromagnetic Compatibility (EMC) requirements and issues to be considered in the future.

1.3 This guidance document is applicable to all types of stand-alone fixed proton exchange membrane fuel cell power generation systems.

1.4 Due to the different fuel types (such as pure hydrogen, hydrogen-rich gas, methanol solution, etc.) used by the power generation system, the purpose of use is different, and the input Unlike the output fluid species and energy forms, they may have different subsystems. However, in order to evaluate the power generation system, it is needed Define a conventional system and its boundaries (Figure 1).

1.5 To determine the test boundary of the power generation system, the following conditions should be considered.

All energy recovery systems should be included within the system boundary;

Calculate their calorific values (eg, pure hydrogen, methanol solution, etc.) based on the state of the fuel at the power system boundary.

1.6 This guideline does not consider the mechanical work or mechanical energy input or output. Mechanical subsystem required for fuel cell operation (eg Fans, microturbines, air compressors) should be included in the test boundaries. There is no need for these mechanical subsystems within the test boundaries Direct measurements, however, their effect on the operation of the power generation system should be included. If the mechanical work and mechanical energy beyond the test boundary, then
