This part of IEC 62282 covers the requirements for the performance test methods of a micro fuel cell/battery power system, consisting of a fuel cell system with secondary battery for laptop computers. For this purpose, this document covers electrical performance test for the fuel cell/battery hybrid system. This document also covers performance test methods which focus on the power and data interchangeability with the micro fuel cell power system and laptop computer and other characteristics for BOP (balance of plant) installed for laptop computer applications with fuel cell/battery hybrid system. This document applies to gaseous hydrogen-fuelled fuel cell power, liquid hydrogen-fuelled fuel cell power, direct methanol fuel cell power, and battery hybrid power pack systems. The following fuels are considered within the scope of this document: gaseous hydrogen; liquid hydrogen compounds methanol. This document does not apply to reformer-equipped fuel cell power systems. A block diagram of micro fuel cell power system is shown in Figure 1. This document covers configuration, the mode of hybridization and operation modes for fuel cell/battery power systems.
