Technical FAQs 4

Do portable batteries need a voltage conversion?

Policies and ethics In portable systems, a number of low-voltage, low-power DC voltage supplies are needed. To provide these from a single battery source, some form of voltage conversion is necessary. To facilitate portability and conserve battery capacity, this conversion should be...

How many watts can a portable FC power?

To power this range of products, portable FCs are being developed in a wide range of outputs, ranging from less than 5 W up to 500 kW. This range has necessitated further sub-classification; ‘FC Today’, for example, classify units with power up to 5 W as ‘micro FC’, and units up to few hundred watts as ‘mini FC’.

Can a monolithic CMOS DC power supply save battery capacity?

To facilitate portability and conserve battery capacity, this conversion should be accomplished in minimal space and mass, with the high efficiency more easily realized in larger converters. A monolithic CMOS DC power supply could meet the severe size and efficiency requirements of a hand-held device.

Who makes portable power units?

Japanese and Korean companies are the most involved in portable power units for electronic devices, and have recently launched a series of products that are mainly based on direct methanol-fuelled PEFC; large-scale commercialization of these devices is planned in the coming years.
