It’s a gas!

Microtechnology is at the heart of a hydrogen powered fuel cell for mobile phones. By Graham Pitcher.

The last few years have seen a growing concentration on the importance of power. The drivers for this interest are multiple. On the one hand, consumer electronics devices are getting smaller, which is bringing the need for batteries with a higher power density, and consumers want longer battery operating life, which is forcing semiconductor manufacturers to make more efficient devices. On the other hand, growing ‘green’ awareness is forcing power efficiency higher up the agenda. This burgeoning market has been attracting interest from a range of companies over the recent past. But one of the leading semiconductor manufacturers is also taking a serious look at the sector – and it plans to use MEMS technology.
