GB/Z 23751.3-2013 Micro fuel cell power systems—Part 3:Fuel cartridge interchangeability

Scope

This guidance technical document specifies the interchangeability of micro fuel cell fuel containers, with the aim of ensuring the safety and performance requirements of micro fuel cell power generation systems while making the fuel containers compatible with various micro fuel cell power units. This guidance technical document stipulates the design of fuel containers and their connection interfaces, as well as requirements for fuel types, fuel concentrations, and fuel quality. It also outlines methods to avoid misconnecting incompatible fuel containers and testing methods to verify that fuels and fuel containers meet interchangeability requirements. IEC 622826100:2007 and GB/T 23751.2—2009 do not address fuel containers and the fuel output from fuel containers. This guidance technical document describes the performance test methods for fuel containers, the fuel output from fuel containers, and the markings used to achieve fuel container interchangeability. It includes the impact of fuel container performance, such as how fuel quality can affect the performance of micro fuel cell power units and the available fuel volume output by fuel containers. A block diagram of a micro fuel cell power generation system is shown in Figure 1. Micro fuel cell power generation systems and micro fuel cell power units refer to portable or easily handheld devices that output a DC voltage of no more than 60 V and a power output of no more than 240 W. This guidance technical document pertains to the fuel containers of micro fuel cell power units and the connection interfaces between fuel containers and micro fuel cell power units. The main body of this guidance technical document includes liquid fuel containers for methanol (including methanol water solutions). Appendix A provides a background on determining the forces expected to be applied during normal operation and foreseeable error conditions. Appendix B provides examples of the design of test fixtures used for fuel connection in
