This part of IEC 62282 provides test methods which are required for the performance evaluation of micro fuel cell power systems for laptop computers, mobile phones, personal digital assistants (PDAs), cordless home appliances, TV broadcast cameras, autonomous robots, etc. This standard describes the performance test methods for power characteristics, fuel consumption and mechanical durability for micro fuel cell power systems with output up to 60 V d.c. and 240 VA. The functional arrangement of a typical example of a micro fuel cell power system, evaluated according to this part of IEC 62282, is shown in Figure 1. This standard does not address the safety of micro fuel cell power systems. This standard does not address the interchangeability of micro fuel cell power systems.
